Light a check on the Matiz. Daewoo Matiz caught fire: reasons and their elimination. Replacing the spark plugs and high-voltage wires

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 dashboard Engine check lights up.

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 an "engine check" appears, will think about serious problems in the car engine, but do not even think to check the tightness of the fuel system, which can be broken due to a defect or not enough tightened neck lid fuel tank. 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 filteras required by the regulations maintenance The car 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!

Modern car Food with electronics. Multiple sensors and signal lights on the instrument panel show different malfunctions. This progress has not bypassed and Daewoo Matiz. The most famous signal is lighting the "Check" function. This is a calling to the fact that there are problems in the engine or control unit.

Video

Video Material will tell you what to do when the engine has caught fire, and also indicates the causes and solutions.

Causes of Silvering the "Check" function

The check signal is usually located in the very center of the instrument combination, where the driver can quickly pay attention to it. This feature is responsible for the operation of the engine and if it signals, it is possible that there were problems in the operation of this particular node. Of course, for any motorist - it's scary, because repair power aggregate Complex and expensive. But, you should not immediately scare and panicing, maybe the reason is petty.

So, consider which the reasons for the fact that the function "Check" on the Matze caught fire:

• If the indicator has worked when the engine starts, it is not necessary to worry, everything works.
• If the "check" caught fire and signal for a long time, then, first of all, it is necessary to make a diagnosis, but only then worries.
• If the "check" during movement is that it may mean that an insufficient oil level in the engine.
• The "Check" function is burning - it is worth checking the motor on signs of depressurization or oil leakage.

If the above reasons did not work, but the "check" is burning, then this may be a signal to the fact that the ignition candle has emerged or is covered with poor-quality fuel.

Safety of the "Check" functions signals that something does not work in engines to diagnose, before taking other actions.

Elimination methods

If you translate literally, then "Check Angie" is an engine error that, according to developers, should indicate the driver to check this system. So, there are several faults associated with the inclusion of such alarm. Consider the main problems in which the "check" occurs.

Poor fuel

Low-quality gasoline, or how in the people they call - "Bodhaya" can cause the engine signaling device to fire on the dashboard. So, troubleshooting can take a lot of time and labor. In order to get rid of the effect, you will have to clean the fuel. To do this, make the following actions:

• Dismantle and rinse fuel tank.
• Remove the fuel ramp and rinse the nozzles using a special stand.

Replace the fuel filter, because as practice shows, then after a poor-quality fuel, it clogs and loses its entire resource.

Spark plug

In case of damage to one of the candles on the dashboard appears Check Engine. To eliminate the problem, you will have to dismantle all the items and check them on resistance, and also visually inspect the condition. Thus, if necessary, it is necessary to replace the candle. As practice shows, it is best to install a fully new kit, which is pre-adjusted, check the gaps, as well as resistance.

Low fuel

With a reduced fuel level on the instrument panel, Check Engine sign pops up, which may also indicate that the fuel tank cover is closed, not completely and the tightness is impaired.

Ignition coil

The absence of sparks in the cylinders immediately signals the electronic unit, which gives the inscription "Check". This is first of all, may be associated with the fact that the ignition coil has emerged. As a rule, it is not repaired and subject to replacement.

Oxygen sensor

Lambda-probe clogging is immediately visible on the inscription on the dashboard. Here, the output can be only one - replacement. Of course, some motorists are trying to clean the oxygen sensor and quite successfully, but in practice - not long and it quickly comes out. Therefore, it is recommended to replace it immediately.

Catalyst

Catalyst can be another reason why Check Engine appeared on the dashboard. Usually, this is due to big mileage car, so when the car begins to take the oil, then it is worth preparing for what this item comes out. But, this is not the only reason. Thus, poor fuel or mechanical damage will result in replacing this node.

Wiring

Cases were repeatedly seen that when problems with the BB-wire pops up Check Engine. Of course, the reason should be looking for in this system and, if necessary, it is necessary to replace.

ECU

The electronic motor control unit may cause the "Check" appearance. So, accumulated errors that have not been dropped for a long time, can serve as a reason for the dashboard will show Check Engine. It is quite simple to be treated for all accumulated errors. But, as experience shows, the case can reach the fact that you have to change software And flashing ECU.

DMVR

The air consumption sensor has repeatedly becomes the reason that Check Engine appears on the panel. In order to determine the serviceability should be diagnosed. If necessary, replace this node.

Underwater rocks

If "Check" caught fire on Daewoo Matiz, then you should not panic. Often on cars, the signal is served from a common computer, which, like any computer can malfunction. This may be caused by a short circuit or replacement of electrical installation elements. Therefore, B. electronic block Management arise errors that can serve as a check "Check".

It is quite simple to be treated with this fault. The computer itself needs to be connected to the program laptop and correct errors in the system or change the outdated firmware. Trust this operation is best to specialists who know how to do.

Output

The causes of the emergence of the "Check" function on Daewoo Matiz are quite simple, since this sensor is responsible for the full operation of the engine. To identify reasons, it is necessary to diagnose and determine why it happened, and only then eliminate it.

Oh, this is an alarming feeling when a yellow icon lights up on the Matiz panel " Check Engine"!
And after all, at the most unexpecable moment, it lights up, as if he depletely the moment when our nervous system is most vulnerable and defenseless!
And you are sitting behind the wheel as in needles guessing, what happened to the car, you begin to listen to the noise of the engine trying to compare with what was "before" and that it was "after" the lighting of this alarming alarm of a kind of vital car.
And paranoid starts! And you feel the skin that the engine works somehow not so, the car has become worse, with a hand and "pull" the car is worse, the transmission began to turn on as not so, the sound of the engine as iron on the glass grinds around the nerves and it seems like more - Choose and you caught the moment when the valve will meet with pistons! And if it happens in a traffic jam ...

What to do? Stop and call the tow truck? Go to service with your course? What if it kills the matizka?!

For many familiar situation, isn't it? And the jog-up surcharge - you know less better sleep, just in this case it does not work at all! Rather, the opposite. And what to do in such a situation? There are no explanation of the information on one forum, but almost every one has a local medium, which on the phrase "I caught fire a check" - immediately displays the diagnosis, reason and recommendations for repair. Quickly, convincingly free. If you follow the advice of a medium technique, the probability of defeating the problem is small, and on the claim, as a rule, the medium techniques are responsible for the same thing: "Well, I don't know ... I was so ...".

So let's try to figure out those secret mechanisms, reasons and consequences that strike our nerves and light anxiously yellow icon. Check Engine On dashboard Daewoo Matiz .

Simple mortals call this lamp indication by a short word "check" or "Chekventin" from the English phrase Check Engine (Check engine) in special technical literature, it can be referred to as a reduction Mil. (MalFunction Indicator Lamp.) Literally - a control lamp of a malfunction. And on slang mechanics with someone light hands Frequently referred to as "meat grinder."

Manages this indication System onboard OBD diagnostics (ON-Board Diagnostics). I think many will be surprised to find out that all these mistakes, which from time to time spoil our nerves were invented to control the emission of harmful substances into the atmosphere with the introduction of various euro standards.
And lighting lamp matiz Check Engine It does not always mean that you need to immediately ride a car.
Engine control unit polls various sensors and if the answer is received beyond the values \u200b\u200bof valid values OBD. Lights indicator. And completely does not care about that panic that this signal can cause the appearance of a given signal to a gentle psyche of the driver.
By the way, one of the most common causes of the lighting of the control lamp is the poorly closed fuel porch cover, since the system of on-board diagnostics is very carefully controlled fuel system Machines including watching and leakage of fuel vapor. Perhaps it is for this reason that it is often possible to hear that the reason for the sunbathing of the notorious "meat grinders" was the refueling "bad" gasoline on some benzocolone.

Lamp lighting Check Engine means that the system ODB. Generated a malfunction code. And what kind of code and what actions need to be taken to eliminate it - without special equipment you will not know. To obtain the required information to the diagnostic connector of the car, you need to connect an error reader or a scanner, which allows you to access data from other sensors and vendors of the car.
W. Daewoo Matiz The diagnostic connector is under the glove compartment and, depending on the year of the car, the connector will differ. After 2008 this is the standard Odbii.For Matzov until 2008 it is a connector.
And not all car services have diagnostic equipment Needless for your car.
Using codes reading devices ODB. You will receive an error code or multiple codes. They will look like this: P0500. or P2141 etc.

Without tables of codes, they mean those or other letters and figures are extremely difficult, and the tables of these are a huge set: generally accepted standard errors ODB., manufacturers errors ( Daewoo, GM, Ford, BMW) And they do not always have their decoding gives a clear understanding where a malfunction, but gives directions to search and saves a lot of time to diagnose.

To describe the system error diagnostics ODB. It is necessary to write not one of the small font with a variety of schemes, tables, notes and footnotes.

And we strongly doubt that it will be interested in ordinary matyus
But we hope that after reading this article, the ordinary driver of the Matiz will understand that the lighting of this indicator does not entail the engine dying after a couple of kilometers or the transmission box. But still it is not worth postponing a trip!

Good day dear, I will write a little as I made a diagnosis on my bug and corrected the fuel level sensor in the gas tank and the error of the error because of which I had a check.

As I wrote, I strangely led myself the level of fuel and the next day the check was caught fire, the engine control error, it did not affect the running properties, but I annoyed me much, I went to a hundred times in the city of Biysk, (110 km. In One end) where I threw up mistakes, they took 500-600 rubles for the diagnostics and after 3-5 days the situation was repeated, I went on the info in Ineta about the ELM 327 diagnostic adapter that can be connected via USB to the laptop and with the help of the program to conduct diagnostics. Progs on the Matiz there are specific there, but in general he sees the computer and erases mistakes, I put two programs. Scanmaster who went with this disk and the MotorDate I was downloaded from the Internet, the very cool one erases, the other cannot, and the next day, on the contrary. Or rather, the viewing and collecting the fuel module, in the hope of correcting the level of the fuel showing (the tracks on the sensor were very subterters) I achieved the results that the arrow rose to zero, although the gasoline was more Polbank, the fuel index is visible on the photo above. So with a non-working sensor error erased the program of the motor (the check caught fire literally in a minute). Today there was a strong desire to dilute again with the fuel module, pulling the fuse of the fuel pump, removing the minus terminal from the battery (it is easier to unscrew on the matze), pulled out the fuel block, removed the fuel level sensor completely, the protector all the raids sliding the contact short one closer, and on a long attacked a soldering iron a little tin, about a millimeter lengthened (the new fuel unit on the Mathiz stands around 6 thousand rubles.) Proterent raids on the sensor and around it (such as coal powder, thin was, black and perhaps the current spent) And also all around, collected everything in reverse order, twisted all the bolts connected the hoses, put the fuse, screwed the mass and started the engine. About the miracle arrow slowly (apparently as pressure in the tank was gained) rose to the level about how it was nalito in a gasoline tank (I know what more Polbanka, and how much I don't know exactly). And so I decided, since everything works erase the burning check, connected the adapter to the computer and the diagnostic connector, turned on the Motor Prog, revealed an error of the non-operating fuel level sensor (old), it is erased, pretext that erases, but the check is burning, turned on the native prog scanmaster , on the third it seems once (or on the second after finding an error) Check went out. On the pictures, the instrument panel before turning on the motor and after the plant, everything works, nothing burns. Came to the conclusion that in my typewriter there was a whole chain of small annoying sores of the check of the check and maybe all this happened due to poor gasoline, on the last refueling when driving a machine to a new place of residence. After replacing the fuel and air filters The oxygen sensor has ceased in the catalyst (Lamd probe seems to be called or there, Sori for technical illiteracy) But helated the check due to the fuel level sensor, after moving the contacts in different directions and wipes, the errors disappeared if you believe the program on the computer and not burning Check on dashboard. Perhaps on this and ended the little things on my pepelats. Otherwise there is nothing even to write, the machine starts with a semi-tier and drives the positive sensations, it is still not necessary to make sure that the fuel index is not lying and everything will be OK, but this will not happen in one day, but as a lump of gasoline in the tank (suddenly just ))) And it will not go down). That's probably what I described everything about my matzik, apparently the habit of after Zhiguli remained to repair, and there's nothing to do with the light bulbs)). But it seems to be corrected, yes, if you believe the Internet on systems with android (tablets, phones) there is a program specifically for matizes (and other machines) in Russian which is easily erased by checks and diagnoses the machines much better than the programs for Windows, on YouTube and just in Ineta Movies are shown and many articles are given to this problem. I hope someone will help this information. We all once again I wish good luck in affairs and life, and safety on the roads.
