I caught fire on Peugeot 408. CHECK ENGINE - What to do? Performance of spark plugs and coils

05.11.2015, 13:21

Last night, having left the courtyard, he clicked on the "gas" and received Jackie Chan. There was a squeak and an inscription appeared on the scoreboard - "The engine is faulty, repair the engine." Battery terminal reset did not help. Signed on checking OD. This morning I went to them when the car was asked for refueling and I decided to refill in front of the arrival .. After refueling, I start the car and I understand that the check was missing. But still decided to get to Peugeot.
The master acceptor said that most likely it was due to poor-quality fuel or the sensor of the exhausted gases buggy, they did not check in general.
But still the trip was not in vain for the guarantees changed the protective plastic on the door racks. :-D.

05.11.2015, 13:31

VIN7421, Oh-oh how, we have our ears drivers that in Ufa Salaar give God, presses with a terrible force: -d. Accordingly, the fuel economy immediately went, the Dvigun immediately like that softly works. The campaign you need to skip: -d.

05.11.2015, 13:47

So it did not complain about the quality of fuel .. everything was fine. Refueling strictly Lukoil and sometimes Bashkirnefteprodukt.

05.11.2015, 19:53

Everything was fine. Refill strictly Lukoil
Two years fired on LUKOIL, and then it turned out to be returned at night from another area, the light was caught fire, LUKOIL needed to look for and here at the entrance to Moscow on Sh. Jitziastov worth the BP, poured full tank And she swept to sleep ... the engine took the paluit and even a bit of his field, yesterday repeated the refueling of BP, suddenly it did not seem :)

05.11.2015, 20:07

It is not very sin on fuel, and the tank was almost dry was already ...

It was necessary to still consider mistakes. With such symptoms, the cooling fan resistor burned down. Periodically, the "check" appeared and sometimes almost immediately, and sometimes some time after some time, having time to switch the engine to the "safe" mode, disappeared. Two months later, 8 thousand runs were replaced by warranty.

07.11.2015, 15:51

Once again, I will go to make mistakes, be sure.

10.04.2016, 09:04

Hello everyone!!! I do not know what topic to write, so I decided here! (if you correct). The problem is as follows how the engine fault inscription was highlighted and the check corresponded, drove around the city, the losses in the traction did not notice only the sound of the motor as it was swimming. Mucky, threw off the stimple, went for a few minutes threw, the check is burning, but the engine works smoothly, after the third plant, during 10 minutes, the check disappeared. I thought that the fuel did not like him, drove after that 350 kilometers a check does not burn. Yesterday made diagnostics and these results in the archive were the error R0088 excessive pressure in the ramp (instead of the 400 with something with something there was 1000 with something). The mistake has not yet been repeated and I hope it will not happen again, before caught the check a check, and pressed the gas pedal to the floor (there was a necessity) and immediately drowned, then after a couple of hours I got started and drove. Error from the archive retired! More errors that could not be removed. R 2133, R 2134 short circuit on + accelerator pedal. The question can anyone will enlighten the TNVD or the nozzle pump, whether it is preparing for the replacement of the pump and what price, well, the tips will be useful who came across or what he thinks about this

10.04.2016, 23:10

we have TNVD, but I think it's not what.
My version: The problem in the pedal, most likely they work in parallel two channels for each parameter that the computer compares the computer.
Excessive pressing was damaged by one of the chains, the signal came to the computer for which it did not correctly issue a command to the pressure control valve.
When you turn on when self-diagnostics, the computer determined the faulty chain and disconnected it.
Now it works on the remaining good chain and reports an error.
In principle, you can ride anything terrible.
Well, to find out the reason you need to start throwing the obviously good pedal and see if the error leaves.

Thank you! Already thought about trying to change the pedals, but where to get it not to buy, the cheapest price is 8200! Does I have a cruise control knob with a limit can it conflict and issue these two errors P2133 and P2134?

11.04.2016, 21:52

12.04.2016, 10:56

yes indeed, p2133 and p2134 from the cruise, looked at himself - the same
Thank you so much!!! I think if you put the joystick without a limit of errors should the abyss ...

Last night, having left the courtyard, he clicked on the "gas" and received Jackie Chan. There was a squeak and an inscription appeared on the scoreboard - "The engine is faulty, repair the engine." :-D.
One in one, last night repeated. But the tank was full, only refuel .. But this time the battery terminal reset helped. I do not even know, go not to go to one.

15.04.2016, 08:49

One in one, last night repeated. But the tank was full, only refuel .. But this time the battery terminal reset helped. I do not even know, go not to go to one.

Do diagnosis, you need to understand what errors pop up, possibly the quality of the fuel is not very good

31.10.2016, 16:02

Please tell me what you can do or what to be ready for. The car is not under warranty. Quietly drove to the village of 135 tons. Km, turned off the engine. After 5 minutes, I turn on the ignition. Error is displayed: "Engine malfunction: repaired car." The engine works calmly, the thrust did not disappear, in general, nothing is usual.
The only frozen frozen has frozen and I periodically started the washer, in the hope that the system has defused. After a while I noticed that the pump does not make up a characteristic noise. A little later I earned the pump. Even before the trip, I referred to the country bang "Gazprom", although I always refuel on Gazprom, but on the same in the city. Therefore, sin on fuel, but again the engine works smoothly. And the latter noticed, it is greatly heated by the regular radio tape recorder. During the trip back to the city, the radio was spoiled, the disk was very hot, even when the magnetic was turned off, the disc was heated, the plastic near the radio is very warm, and a little further cold. Hence Domka, maybe somewhere korotitis?

31.10.2016, 16:26

Grifq, I would start with diagnostics, see what an error, and then by results. Radio works or not? Heavily warm the radio may be due to the closure of the wires on the speakers among themselves or for the mass. Dynamics and wiring to them regular? If they changed to others - check for closure, at least visually. There are no rare cases when the speakers are installed with greater planting depth and the wires are cling to the glass when it is lowered. Could tear off the wire from the speaker and closer to the mass ...

31.10.2016, 16:47

All the regular, nothing was done by IPA changed

31.10.2016, 16:50

Calmly drove to the village of 135 tons km,
However, you don't have a village * crazy *
In general, of course, you need to start with reading errors and already repel from it.

31.10.2016, 16:58

I hope it will be not expensive ....

31.10.2016, 22:46

In general, the evening "Check" disappeared. However, the radio is buggy, then reads discs and a flash drive, does not read. Radio works. Perhaps because of the weather, wires or something else, I do not know. The entry in the engine malfunction log is not preserved, in any case, the display is no longer displayed.

31.10.2016, 23:52

01.11.2016, 11:41

135 km)) I spoke about Magnitol because it began to bite in front of the "Check" icon. The disc is very hot, more precisely to say not normal hot. It is clear that it heats, but also hesitated (now there is no longer) and when the radio tape recorder is turned off. Also, I specifically included the cold stream without a stove, and the tape recorded turned off (the radio also off) remained hot. In general, I will not scan nothing, until the next "check". Magnitol like earned.

Unstable work gasoline engines Franco-German development EP6, which are installed on Peugeot 308, quite frequent phenomenon. The engine begins to trim on the cold, the fan is turned on, the check is lit, a word, pleasant enough. The reasons for such a motor behavior are absent, we have to consider them and try to find a decision to restore performance.

Why the fan turns on when the engine troit on Peugeot 308

Check all possible reasons.

The constant switching on the fan, regardless of the coolant temperature in the system, is a sign of almost any malfunction in the engine.

Even with one non-working spark plug, the fan will blow maximum turnover and it is quite normal in this case. If a few more problems are joined to the fan, then there is an opportunity to localize or at least assume the cause of the malfunction.

Here are the main reasons for the vibration of the motor (Troit and works with interruptions):

• one of the spark plugs does not work;
• one of the ignition coils does not work;
• ignition passing in one particular or in several cylinders;
• air seats into the combustion chamber;
• failure of the catalyst, incorrectly removing the catalyst without updating the firmware of the computer;
• incorrect operation of the gas distribution mechanism;
• fuel poor quality.

Perhaps these are the main causes of such a behavior of the motor, and they will have to be considered individually.

Troit Engine: Checking Candles and Coils

Naturally, when this bouquet of faults appears, the most correct to get to the diagnostic center. There, the diagnostic equipment will be accurately verified and errors () will be installed. However, at the initial stage, you can conduct diagnostics with your own hands, pushing out testimony on-board computerand sometimes without them.

The most common cause of the unstable working cylinder is the failed coil, candle or nozzle.

What cylinder Troit (Cold Check)

We find out which cylinder does not work on cold at idle:

1. Open the hood, remove the plastic cover of the block head.
2. Run the engine.
3. Alternately remove the pulse wires from the ignition coil of each of the cylinders.
4. If the engine operation mode changes dramatically when the cylinder is turned off (coil and), it means that everything is in order.
5. Disabling the non-working cylinder does not affect the operation of the motor at idle.

Suppose we found out the number of the non-working cylinder.

Performance of spark plugs and coils

Old candles are one of the possible causes.

Now it remains to check the efficiency of the coil and candles.

We change in places Presumably non-working coil with a working and launch a motor at idle. Removing the signal wires alternately from these coils, we find out whether the assumptions were confirmed about the non-working coil - if a healthy cylinder stopped working, the coil is to blame. If non-working cylinder continues to be silent - the candle is to blame. Conclusion - replace the ignition coil and whenever possible candles in cylinders.

ATTENTION: When replacing candles, in no case you can not throw a new candle in the well, otherwise there is a danger of bringing down the gap between the electrodes, then new candle may not work. It gently descends into the well and twists strictly along the thread with a special key.

If at this stage failed to find a malfunction, go to more radical measures.

Pass ignitions on Peugeot 308 - What is it?

I can also determine the skip in spar form diagnostic equipment. Here are the main symptoms:

• troit engine;
• the check is burning;
• the fan is constantly working;
• power drops sharply and;
• an error message appears.

On Peugeot 308, the ignition error error codes begin with p1336 (skip, the cylinder is not defined), in order to P1340 (skipping sparking in the 4th cylinder).

Actual errors.

The causes of the skip can be mass - from poor quality fuel, to insufficient compression in a certain cylinder. If we have already replaced the candles, everything is fine with the coils, then you measure compression. Nominal - 12.6-13 atm In each of the cylinders. If compression does not match the norm or one of the cylinders has a low compression - it will say that floored compression rings, Air seats, malfunction in the gas distribution mechanism are possible.

Problem with nozzles

Scored nozzle.

Errors P1336-P1340. Also may arise due to faulty or scored nozzle.

In order not to remove the ramp, you can check the resistance at the outlet outputs. This requires a multimeter in resistance measurement mode.

Nominal nozzle resistance - 12.6-12.8 Ohm.

You need to check it only at the time of failure. If everything is fine with resistance, it remains - it is better to do with a special fluid on a flushing stand.

Problem with TRM

Problems with the gas distribution mechanism with their own hands to determine and eliminate not easy.

To do this, you need to remove the head of the block and to diagnose visually, as well as measure the height of the lifting of the valves. For example, on EP6 engine, the height of the lifting valves on idling - 0.4 mm , and on high speed - about 4 mm . For the change in the phase, the BMW VVTI system is responsible, in which it is rather difficult to understand.

Frequent breakdown at the 308th - dissue or Valve Saddle Loss , Nagar on the valve, which will also call the above errors and symptoms.

Separe air

Air seats can appear in several places:

• laying block head;
• laying intake manifold;
• soothing through nozzles connected to the intake manifold;
• failure or clogging of the EGR valve.

conclusions

Most of these faults are eliminated and diagnosed to a service station, the most common and simple problems can be completely eliminated independently. Let your engine work without interruptions, and the roads will be smooth!

"Chot Check Engine - what to do?

CHECK Engine caught fire - we understand the causes of car malfunction

Many owners passenger transport For the time being, they do not pay attention to devices and light bulbs that do not serve "disaster signals." The owners of steep foreign cars, stuffed electronics, which means Check Engine.

For us drivers

When the light lights up, at best the drivers ask themselves the question: why is she caught fire and what to do?

Indeed, what measures do you need to take when?

1. First, the reasons for sunbathing light signal Maybe several.
2. Secondly, the problem often has to look for for a long time and without computer diagnostics not enough.

Some Likbeza

Most cars that came out of the factory gate to date, equipped with a signal lamp installed on dashboard - Check Engine.

The active light bulb indicates that it is necessary to check force aggregate. The control unit discovered a certain problem and tells you about it.

In the early 80s, cars were equipped with mini-computers carburetor control. Gradually, the scope expanded. Currently, on cars, "silent controller", which has passed serious evolution, is watching:

• for the composition of the feed combustion mixture,
• fuel consumption,
• turnover of the power unit,
• the moment of ignition.
• controls shifting gear into automatic transmission.

Which of this is not a complete list of control functions, can I make a logical conclusion? That's right, the reasons for the lighting of the Check light bulb is more than enough.

Consequently: without certain knowledge and practical skills, it is extremely difficult to identify the reason for sunbathing the control light.

So what needs to be done, what actions to do? Let's deal with together!

Caught Check Engine , how to proceed?

Did you know,

what is the lighting of the check engine indicator - is it a non-configuration engine fault verdict?

1. If a check. Indicator Engine When starting the power unit, signals problems, and immediately goes out - you should not worry. Your engine is not subject to "technical diseases", is in good condition and is not subject to "treatment".
2. When you turn on the engine after the appearance of the light warning, Check Engine is not turned off for a long time - it is worth thinking. Surely problems arose. They can wear a large or insignificant nature. It is better not to risk and refer to specialists.

What makes "blush" Check Engine?

• If driving a car, you have noticed, there may be a lack of oil level in the power unit in the power unit. In this case, it is recommended to make a stop and without turning off the engine, opening the hood to listen to the operation of the aggregate. If the motor works exactly: no scrolling and extraneous noise or knocking, pay attention to the tightness. You may find items on the engine housing. It is recommended to seek advice and resort to the help of Masters a hundred.
• Perhaps the Check Engine warning signal is associated with ignition candles. Most likely, one of them fell out of the order (ignition pass).
• Caprizes CHECK with poorly fuel, which often happens when refilling. This problem is manifested as soon as you drove off the gas station.

Consider the options for sunbathing light bulbs Check Engine and solving problems

This is an incomplete list of reasons affecting the lighting of the check engine light bulbs.

Eliminate errors without using a diagnostic scanner can be independently. Drivers with experience eliminate the error in this way. Unscrew the battery terminals. Put them in the direction, not allowing short circuit.

Waiting time for no more than 20 minutes. If connecting the battery and starts the power unit, you see the reversed clock and extinguished the control check Engine Light Bulb You coped with the task. However, you need to remember that accumulated errors are taken. The real problems of the power unit will appear on the second day of the vehicle.

How to check high-voltage wires

CHECK ENGINE LIGHT CAGN

Perhaps the case in high-voltage wires? Sometimes it happens.

Tip: follow and accurately follow the instructions.

Fill with liquid with a saucepan. You can use an ordinary saucepan. Mandatory from stainless steel. Add a little salt. There will be enough 1 tablespoon. Take a megommeter, lowering the wires into the water. Ends must be on the surface.

We carry out the connection of the device to 1 tip. With the help of the clamp fix. 2 clamp put on the container, where the wires are left on the water surface. If the resistance shows more than 1 megoma - isolation in good condition. In some cases, the value is not lower than 500 com. If the indicators will be lower than the critical mark, the wires are required.

Recommendation: if the methods of self-conducted diagnostics did not give a positive result (still burns check Light Bulb Engine) Requires specialists. And urgent! Otherwise, the problem may be large-scale.

Tips for those who are on the road

No matter how well you have disassembled in cars, but specialists are in service with special technique, they are more understood in the emergence of one or another cause of the "alarm". Moreover, the Masters one hundred permanent practice, and this is the experience of which does not take away!

Specialists do not recommend to take some kind of fault correction measures. If you are not sure about your abilities, it is best to call the tow truck and send a car to the nearest station maintenance.

As a rule, many car manufacturers, Check Engine lights light up when the engine disorders are associated with injection disruption and worsening exhaust, which will be strongly influenced by the ecology.

Diagnostic work is the first step towards clarifying possible problems. A brief diagnostics will show that he influenced the lighting of the bulbs, and the wizard will set out the essence of what is happening.

Going to a service station and driving a car must comply with precautions.

• Do not load the power unit
• Try to ride with a constant speed not exceeding 60 km / h.
• Control the level of revolutions. Do not allow a transition for a 2500 rpm mark.
• Reduce load. Somehow turn off the air conditioning system and other additional equipment. Refuse from the work of the favorite multimedia system. Turn off not affecting normal and safe traffic Car electrical appliances.
• Ride smoothly, not allowing sharp accelerations and emergency braking.
• Driving to Maintenance Station Plan to make in a bright day of day. At night, the headlights create additional loads on the power unit. You can move at night under the condition of increased attention in compliance with the above conditions.

The usual driving style is possible after checking the car and recommendations of specialists of a hundred.

And further

It should be understood that the check engine can light up at any moment. This is not a reason for panic, but only a warning about possible faults. Ignore warning signal Check Engine is not recommended. Since the consequences of a dismissive attitude towards warning devices are fraught with serious consequences.

Diesel does not start, malfunctions and causes
Designations of icons on the instrument panel - what do you mean Airbag light bulb Peugeot errors 308, 408, 3008 Why the diode bridge of the generator burned down Lamps in Peugeot - Replacing light bulbs in Peugeot

Many of us have come across such a problem as the inclusion of the engine icon indication (Check Engine ...), the appearance of which scares car drivers. We offer you the 5 most common reasons for which the engine check lights up on the dashboard.

The appearance of the engine indication icon occurs, as a rule, without warning. The reason for the appearance of Check Engine cannot be immediately understood. Even if there is a car diagnostic in the car (for example, in such cars, as,), which scans all the car systems on errors and when they are presented, displays the decryption to the information panel, the causes of the engine check will not be decrypted.

For most drivers, the appearance of this warning icon on the instrument panel means the need to urgently go to the auto repair shop to diagnose and eliminate the reasons for which the warning sign "engine check" appeared. But in most cases, in most cases, when the "Check" appears, it is possible and in some cases, it is possible to eliminate the cause independently without a trip to the car service, which will save your money.

1. Replace oxygen sensor (lambda probe)

Oxygen sensor in your car is part of the system of working out exhaust gaseswhich controls how much oxygen has not burned in the engine combustion chamber. This sensor helps to control the fuel consumption of the car. Fault oxygen sensor (lambda probe) means that automotive computer Gets not the right data, which can significantly increase fuel consumption and reduce engine power. Most cars have from 2 to 4 oxygen sensors. If you have a home automotive error scanner, then you, by connecting it to the car, can easily find out what sensor must be replaced.

For whatever reason, the oxygen sensor in the car comes into disrepair: Over time, the sensor is covered by a layer of spent and motor oil (oil soot), which reduces the accuracy of the removal of the sensor indicators to regulate the gasoline mixture and the distribution of optimal. The oxygen sensor malfunction in the car leads not only to, but also to elevated content harmful substances CO2 in the exhaust.

What needs to be done: If you do not change the faulty automotive oxygen sensor, then this may lead to the failure of the catalyst of your car (can burst), which will turn into expensive repairs. The cost of new catalysts is very high due to the content of precious alloys in them. On some cars, catalysts several pieces whose cost can reach up to 90,000 rubles. So do not pull with the sensor replacement. Although the sensor replacement and its cost is not very small, but it is incommensurable with the cost of the exhaust gas neutralizer system. You can also save on a replacement by making it yourself. In many manuals for car operation detailed instructionsHow to independently replace the oxygen sensor. If you know where the oxygen sensor is located, then you will not be much difficult to disconnect the defective "lambda probe" and replace it with a new one. Remember that it is impossible to pull with the replacement of this important item!

2. Check the fuel tank neck

Many drivers in most cases, when displaying the "engine check" appears, will think about serious problems in the car engine, but do not even think to check the tightness fuel systemwhich can be broken due to a defect or not sufficiently tightened with a fuel tank neck. This is a very common cause in the appearance of the engine "Check" engine.

Cause of error appearance: The leakage of the fuel system due to air transmission, the fuel tank fuel cap will increase the fuel consumption of the car, to which the car's diagnostic system is issued an engine error by turning on the "Check Engine" indication on the instrument panel of the automotive instruments.

What needs to be done: If, when the "Check" appears, your car has not lost power, and there are no sound signs of engine damage (knock in the engine, hum, creak, etc.), then check the tightness of the gas tank. It is possible that the lid of your fuel tank has cracks or is not tightened enough. If the lid was not tightened enough, then tightening it to the end, continue the car by car for a while to watch the engine error disappear. In order to prevent the occurrence of the engine check for this reason, check the fuel tank neck cover regularly. Remember that periodically the cover must be changed for a new one!

3. Car exhaust gas catalyst

The car catalyst helps the car make the exhaust of the motor exhaust gases are more environmentally friendly. It converts carbon monoxide and other harmful substances in harmless compounds. If your exhaust exhaust catalyst has become unusable, you will notice it not only when the engine icon appears (check), but also long before that when the car's power falls 2 times. For example, when you press the gas pedal, the car, as before will not have good overclocking dynamics.

Due to which the automotive catalyst may fail: If you regularly serve your car, in accordance with the Regulations, automotive company, the catalyst should not fail. The main reason for the failure of the catalyst is not timely replacement Faulty oxygen sensor, as well as non-regular replacement of spark plugs, at the end of the shelf life. When the oxygen or spark plug sensor is faulty, then the conversion of carbon monoxide in the catalyst in harmless chemical elements is terminated, which leads to overheating of the catalyst, which due to this may fail.

What needs to be done: If your catalyst has become unusable, then you cannot ride a car, since the engine will not work correctly, warning about this indication on the dashboard of the engine icon (check). Also, you will be very much increased fuel consumption, and the engine will be missing. Although the catalyst replacement is very expensive repair, it is not where not to go from repair. Although there is an alternative to replacing the catalyst on the planeencitel, but this is not 100 percentage option. Unfortunately, if you are not an experienced car mechanic, you cannot replace the defective exhaust gases catalyst yourself. In any case, you will have to contact the car repair shop. Remember that the timely replacement of oxygen sensors and spark plugs protect your catalyst from breakdown!

4. Replace air consumption sensor

Sensor mass flow The air regulates how much air must be added to the gasoline mixture for optimal fuel ignition. The sensor constantly reports the car computer data on the amount of oxygen supplied. Faulty air flow sensor increases fuel consumption, increases CO2 level exhaust GasAnd also reduces the engine power and smoothness. Also, when a faulty sensor is observed bad speaker overclocking. In the cold time, the car with a faulty sensor is badly started.

What are the reasons for the failure of the mass flow sensor: Most sensors breakage occur due to improper installation of the air filter when it is planned. Also if you do not regularly change air filterAccording to the car maintenance regulation recommended by the manufacturer, the mass flow sensor can fail.

What needs to be done: Theoretically you can ride a broken air flow sensor for a long time (several weeks or months). But you will notice that the longer you drive, the more fuel consumption consumption increases. Replacing the sensor in the car service is not as expensive, since the work itself does not take much time and is sufficient. Basic costs are related to the cost of the sensor, which on some cars can be 11,000-14,000 rubles, if it is an original sensor or up to 6000 rubles, if an analog substitute. Independent replacement The sensor is very simple. But due to the small cost of work on the replacement of the sensor, you can entrust this work and the master in the car service. Remember that you need to regularly change the air filter, observing the regulation of the car!

5. Replacing the spark plugs and high-voltage wires

Spark plugs in the car are the main items for ignition fuel mixes. With defective ignition candles, the spark is incorrect for inflammation of the gasoline mixture. In defective candles, there is often no spark or incorrect spark interval, which affects the improper operation of the engine. With the wrong work of the candles during acceleration, especially from the scene you can feel small shoes.

What are the reasons for the failure of the spark plugs: Most of the spark plugs in cars until 1996 release must be changed every 25,000-30,000 kilometers. In newer, the ignition candles are more than 150,000 km. However, these terms of planned replacement of spark plugs may decline at the expense of various factors associated with fuel quality and driving style.

What needs to be done: If your candles did not change for a long time, or you feel in the work of the engine failures associated with the ignition, then it is necessary to immediately replace them with new ones. Do not attempt to save on undime replacement Ignition candles, since the candle value is not very expensive, as well as work to replace them. By changing the old spark plugs, you will improve the engine operation and reduce the fuel consumption of the car. Independently change the spark plugs quite easily. Mostly they are in easy accessibility under the hood of the car. You need an ordinary candle wrench to unscrew the candles from the engine. It is also desirable to monitor the state high voltage wiresSince over time they can come into disrepair and pass electricity, which is transmitted by ignition candles, which will reduce the strength of the spark. Remember that the regular replacement of the candles, in accordance with the regulatory of the maintenance of your car, retains your exhaust gas testing catalyst from breakdown, and also improves the operation of the engine!

If something is wrong with Peugeot 408, then "Check-engene" does not go out, or lights up again after a while. He may flash, which unequivocally speaks of a serious malfunction. This indicator will not inform the Owner Peugeot to exactly the problem, it draws attention to the fact that the diagnosis of the Peugeot engine 408 is required.

Since all foreign cars, not excluding Peugeot 408, tightly tied to electronics, A huge number of sensors follow the operation of the car. Therefore, the Diagnostics of the Peugeot engine 408 is by and large checking the most important assembly of the machine, with the exception of the suspension, which is verified by mechanical path.

There are a large number of specialized equipment for the diagnosis of the Peugeot engine 408. There are compact and fairly universal scanners, which can afford not only professionals. But there are cases when ordinary portable scanners do not detect malfunctions in the operation of the Peugeot 408 engine, then the diagnostics should be carried out exceptionally licensed on the PEUGEOT scanner.

PEUGEOT diagnostic scanner shows:

• The magnitude of the opening throttle valve in percents;
• Engine turnover in rpm;
• Temperature of the engine Peugeot 408;
• Voltage in the onboard network Peugeot 408;
• Air temperature absorbed into the engine;
• Ignition ahead of the ignition of Peugeot 408;
• The fuel injection is nozzle. It is displayed in Miliseconds;
• PEUGEOT 408 air flow sensor readings;
• Indications of the oxygen sensor Peugeot 408;

1. To diagnose the Peugeot 408 engine, first of all, the subcontrol space is visually inspected. On good engine should not be any inclination technical fluids, Whether it is oil, coolant, brake. In general, it is important to periodically clean the engine Peugeot 408 from dust, sand, dirt, it is necessary not only for aesthetics, but also for normal heat dissipation!

2. Check the level and condition of oil in the engine Peugeot 408, the second test step. To do this, you need to pull the dipstick, and also look at the oil by unscrewing the bay lid. If the oil is black, and even worse, black and thick, it indicates that the oil has changed long ago.

If there is a white emulsion on the filling lid or it can be seen how oil is foaming, it can talk about water from or coolant into oil.

3. Checking the spark plugs Peugeot 408. Remove all the candles from the engine, they can be checked by one. They should be dry. If the candles are covered with a minor layer of yellowish or light brown Nagar, it is not worried about, such a nagar is quite normal and permissible phenomenon, does not affect the work.

If the pendaches of Peugeot 408 there are traces of liquid oil, then most likely to replace piston rings or oil-challenged caps. Black Nagar testifies to the re-entered fuel mixture. The reason is the incorrect operation of the Peugeot fuel system, or too clogged air filter. The main symptom will be increased fuel consumption.

Red peegeot 408 candles is formed due to poor-quality gasoline, which contains a large number of metals particles (for example, a manganese that increases octane number Fuel). Such a flare spends the current well, which means with a significant layer of this plaque, the current will go on it without forming a spark.

4. Peugeot 408 ignition coil fails not often, Most often it happens due to old age, insulation is damaged and a closure occurs. Change the coils are better in accordance with the rules mileage. But there is a breakdown cause bad candles or punched high-voltage wires. To check the Peugeot coil, it must be removed.

After removal, you need to make sure in the integrity of the insulation, there should be no black spots or cracks. Further, the multimeter should go into the move, if the coil burned, the device will show the maximum possible value. You should not check the Peugeot coil 408 by the Dedovsky method for the presence of sparks between the candles and the metal part of the car. This method takes place in old cars, while on peugeot 408, because of such manipulations, it can not only burn the coil, but also the entire electric car.

5. Is it possible to diagnose the engine malfunction for smoke from exhaust pipe Peugeot 408? The exhaust can tell a lot about the state of the engine. From a good car in the warm season, there should be no thick or nasal smoke at all.

If the white smoke is visible, it may indicate a burned gasket or not tightness in the refugee cooling system 408. If smoke is black, then at best these are problems due to a rejuvenated fuel mixture. At worst - problems with a piston group.

If smoke has a bluish shade, then this suggests that engine Peugeot. 408 Consumes oil. At best, it will be necessary to replace the oil-changing caps, at worst - repair of the piston group. All this GAR is strongly clogging and reduces the life of the Peugeot 408 catalyst, which does not cope with the purification of such impurities.

6. Diagnostics of the Peugeot engine 408 by sound. The sound is a gap, which is exactly what is said in the theory of mechanics. There are gaps in almost all moving connections. In this small gap, there is an oil film that does not allow the items to touch. But over time, the gap expands, the oil film can no longer be distributed evenly, the parts of the peugeot 408 motor parts are friction, as a result, it begins very intense wear.

Each node in the engine Peugeot 408 is characterized by a certain sound:

• Ringing, frequent sound, audible on all engine speed, indicates the need to adjust the valves;
• A smooth knock, which does not depend on the revolutions caused by the valve distribution mechanism, which indicates the wear of its elements;
• A distinct short knock, increasing on high revs, warns about the imminent end of the connecting rod insert.

7. Diagnostics of the Peugeot Engine Cooling System 408. With the proper operation of the cooling system and sufficient heat sink, after the start of the engine, the liquid circulates only for a small circle through the stove radiator, which contributes to rapid warming as the engine itself and the Peugeot 408 salon in the cold season.

When normal is achieved working temperature The engine is Peugeot 408 (about 60-80 degrees), then the valve is opened on big circle. The liquid partially flows into the radiator, where it is warm through it. In the event of a critical mark of 100 degrees, Peugeot 408 thermostat opens to the whole, and the entire volume of the fluid passes through the radiator.

At the same time, the Peugeot Radiator Fan 408 is included, it contributes to the best blowing of hot air between the coolant cells. Overheating can output the engine and will need expensive repairs.

8. Typical malfunctions Cooling system Peugeot 408. If the fan does not work when the critical temperature is reached, then first it is necessary to check the fuse, the fan of the Peugeot 408 fan itself and the integrity of the wires to it itself. But the problem may be global, the temperature sensor (thermostat) failed.

The performance of the thermostat of Peugeot 408 is checked as follows: the motor is pre-warmed, the hand is applied to the bottom of the thermostat, if it is hot, it means well.

More serious problems may arise: failure, flow or clogged radiator Peugeot 408, break the valve in the lid of the fuzzy neck. If the problems arose after replacing the coolant, then most likely the air traffic jam.
