How to configure the throttle sensor by a multimeter. Throttle position sensor: How to check, replace, adjust. Has the throttle position sensor gives the correct signal

Sensor throttle valve It is an important detail in any car - this mechanism is a link between the controller and the throttle. He starts his work immediately after the gas pedal is pressed. The violation of the throttle sensor is caused by the engine malfunction, since the controller that binds to it adjusts the fuel supply from the tank. Each driver knows that such problems can provoke an increase or decrease in the amount of fuel supplied. In the worst case, the car may fail, but if you identify problems and eliminate them in time, you can avoid engine problems.

Where to look for a damper sensor?

To troubleshoot problems, you need to know exactly where the desired throttle sensor is located. Sensor is B. motor compartment Machines, opening the hood, you can easily find this place. The axis of the throttle connects the nozzle with the direct mechanism. The reasons for anxiety may be such:

• increase idling in the heart of the engine;
• engine plug on neutral transmission work;
• swimming of idle speed;
• failures in dynamics;
• purchase button " Check Engine".

Such signs may arise if one of the moving cores has failed, which provoked a violation in the engine. When examined, also pay attention to the state of spraying in the slider. If the spraying disappeared or became white, then this may indicate a violation of the engine operation. There are other reasons for problems with fuel control, you can diagnose them only with special equipmentWhen you can cope with this work, you can cope with this work.

Many motorists are wondering how to check the throttle position sensor? To do this, you need to allocate some time and make such operations:

• turning on the ignition, you must connect the voltmeter to the mechanism to check the voltage between the slider and the minus indicator. The norm is an indication corresponding to 0.7 V;
• next, you must fully open the damper. To do this, you need to turn the plastic sector, in this area the indicator should be 4 V;
• check the resistance between the contact slider and any output, before this it is necessary to turn on the ignition and pull out the connector;
• slowly and smoothly turn the sector, watching the voltmeter indicator, the arrow should move evenly and smoothly, the failures during the arrow indicate the throttle damage.

In order to avoid breakdowns, you need to select suitable throttle sensors. Film-resistive throttle valves are most often used. It is such sensors that are installed on the factories, but they are not always suitable. A universal option is a contactless throttle sensor, this mechanism copes perfectly with its work and almost never fails. The advantage of this device is that it works on magnetoresistive technology, it helps to reduce the probability of breakdowns. Magnetic fields affect the valve axis, changing the resistance, due to this changes occur in the sensor indicators. This type The throttle valve has a high price, but using them, you will realize that the price fully justifies quality. The service life of such a mechanism is much longer than other species. Using the contactless throttle recorder, you can get rid of many problems. Modern technologies Allow to simplify car care, which is why auto mechanics advise the use of magnetoretive systems to regulate the fuel supply to the engine.

Principle of operation and structure

The sensor in its structure has three outputs:

• the first to supply voltage to other levels;
• the second performs the function of the compound with the bulk;
• the third reads the signal from the motor control unit.

The closed throttle indicates the minimum voltage on the sensor indicators. The mechanism works as a potentiometer.

An important indicator of the throttle is the size of the air duct, it is this value that solves a major role in choosing a sensor. The large diameter of the throttle channel will help reduce resistance in the mechanism, the air will go to the engine to a lesser extent, and therefore the operation of the motor will be significantly better. For prophylaxis, it is necessary to periodically clean the channels and the damper itself to avoid trouble.

In the picture, you can see a schematic connection of the throttle position sensor with the engine control center. As you can see, the mechanism has three outputs, each of which is intended for a specific purpose.

Any violations in these compounds may damage, which can be displayed on the engine. It is for this scheme that all the elements of the system must be connected.

Conducting adjustment procedures

Remember that the adjustment procedure is performed solely on the average level of the ignition connector:

Common sensor malfunctions

Very often over time, the throttle sensor fails due to the substrate malfunction, which is covered with a resistive layer. When this layer is erased or loses its properties, the sensor starts to flure. In this case, it is necessary to replace the substrate so that the sensor can easily read linear movements inside the mechanism.

Another important detail is the slider. The cause of problems can be a violation in contacts between the slider and the resistive layer. As a result of this, loops are formed on the surface of the layer, which interfere with the operation of the mechanism.

The best option is an full replacement Old throttle sensor for new. It makes no sense to change individual details, since after a certain period of time, the problems may return and eliminate them will be more difficult. On such models of cars, like VAZ 2110, VAZ 2114, 2112, you can easily reinstall DPDZ.

Often there is a problem with the oxidation of contacts. In this case, can help special fluidwhich you need to process all available contacts.

It also happens that the damper is closed not to the end, as a result of which the fuel supply can be distributed unevenly and incorrectly. With this difficulty, you can easily cope if you cut the extreme parts of the mechanism so that the flap is tightly closed on both sides.

Many motorists, finding gaps in contacts or cracks in the area, resort to the use of conductive glue. Of course, for a while, the operation of the mechanism is restored, but the sensor itself will never be the same, therefore it is advisable to simply purchase a new device to avoid problems in the future.

Most auto mechanics use film-resistor throttle, as they have relatively low cost and sold in all stores. Sensor Replacement - simple procedureBut requires attention and prudence.

Procedure for replacing the mechanism

The throttle sensor replacement operation must be approached carefully and consciously. Prepare all the necessary materials and equipment. Consider the stages of the throttle sensor replacement:

Never forget that the car needs concern. Repeat the engine periodically, check the contact resistance and the level of vibration at the required areas. Always have all the necessary measuring equipment in your garage. Having studied some features of the structure of your car, you can always come to his aid in time if something goes wrong. It is better to carry out prevention in time than to spend many money to repair the car.

The throttle sensor is a very thin and vulnerable mechanism, so it needs great attention, but if you systematically check its condition and help contact, your car will serve you a long faithful service.

Lost valuable fuel does not want anyone, so you need to always control the work of the damper sensor. For a hundred checking can do to you in a penny, while you yourself can spend all the necessary procedures in your garage.

Buy throttle sensor for you will not be difficult. In any specialized store there big choice Similar mechanisms. According to specialists, problems with DPDZ are found quite often, it is the breakdown of this mechanism that the car's cap is caused among the road. So that this does not happen, treat carefully to your car and spend prophylactic work on time.

To detect the throttle sensor fault, start from the device itself. It is no secret that this element works in close interaction with the car engine, therefore it is in close proximity to it. First, find the throttle nozzle, and leave it to the DPDZ itself. The sensor, one side, is fixed to the nozzle, and the other is connected to the axis of the throttle of the throttle.

How to recognize breakdown: basic symptoms

The car owner should know how to identify the malfunction of DPDZ. It is easy to do this, but for accurate definition of a malfunction, it is worth knowing its symptoms and respond to them in a timely manner. The main features of the sensor malfunction should be attributed:

• There are problems on the XX when the motor operation (swinging turns).
• The engine stalls at the time of translation of the PPC selector (when the speed is turned off during the movement).
• Increases fuel consumption.
• There is instability in the turns of XX, regardless of the mode of operation of the motor.
• The engine power is noticeably reduced.
• Rod felt, during overclocking and when moving at low speed.
• The motor stalls when the accelerator pedal is released (at idle).

In some cases, malfunctions associated with the failure of the throttle sensor manifest themselves with a reference to the check engine control lamp, located on the instrument panel and signaling about the presence of problems with the engine. At the same time, the light can light up periodically (with this moment we will figure it out below). Whatever the symptom of malfunction, it may indicate the problem and the need to take appropriate measures to eliminate it. In such a situation, it is important to immediately fulfill some work (about it below).

The photo shows where the DPDZ is located

How to check the performance of the sensor?

If during operation, one or more of the signs mentioned above, it can be assumed to malfunction of the DPDC. The first thing to be done is to check the DPDZ in good condition. The performance of these works does not require any special preparation from the car owner. The main thing is to clearly represent the sequence of actions and have a multifunctional device at hand (multimeter).

It is worth recalling that the Check Engine light is designed to remind the driver about the presence of engine problems. When it is sunbathing, it is worth contacting a hundred or to identify a malfunction yourself. In the absence of errors, the lamp lights up at the time of starting the motor, and after the completion of the diagnosis, immediately goes out. If this does not happen (the bulb continues to glow), it means that there is a problem in the system, and without an experienced master, it will not work out.

By the way, the above information is more for general development. As for the malfunction of the DPDZ sensor (throttle), it is required to operate here by such an algorithm:

• First of all, turn off the ignition. Exercise dashboard And make sure that Check Engine light bulbs are absent. As noted, this lamp is a direct reminder to the driver about the presence of problems. If it was extinct, open the hood, to access DPDZ, and check the device.
• Prepare a multimeter, with which further verification will be performed.
• Check the presence of "minus".
• If there is no desire to cast each wire, make it easier - pierce the necessary wires and measure. Similar steps to search for "Mass". Ignition, during the verification process, it is not required.

After the preliminary work, your task is to check the fact of the supply of nutrition on DPDZ. It costs that the voltage directly depends on the model vehicle. For some machines, this is 5 volts, and for others - 12. To determine the malfunction of DPDZ, act according to the following algorithm:

1. Turn on the ignition and pierce the wire of the desired chain alternately. The multimeter display should turn around the parameter 0.7 V.
2. Open the throttle of the throttle manually and look at the device. Now the voltage should be higher than 4 volts.
3. Turn off the ignition and discard one connector. Immediately after that, connect the dipstream multimeter - between the remaining wire and output from the slider.
4. Scroll the sector manually and follow the instrument readings. If they grow without sharp jumps, the throttle sensor is functioning correctly, and there are no malfunctions. Otherwise, we can talk about the formation of scrap (damage) on the track of the resistor.

The indicators mentioned above are important, because they directly affect the correct operation of the ECU block. The task of this electronic device It is the control of the main processes of the motor, including the supply of fuel to the injectors. If the control unit receives incorrect numbers, then the solutions them are also erroneous. For example, the throttle of the throttle is fully open, and the ECU still sees it in a closed position. If there are similar symptoms, the malfunction of the DPDZ is obvious and the device must be changed.

Throttle position sensor

The procedures described, to identify breakage, is not always enough. In some cases, additional inspections may be required to eliminate faults in the future. When identifying one of the following problems, it is better to change the sensor. Moreover, the cost of the device is low, and after replacement, such long-stayed stability will appear in the operation of the motor.

Pay attention to the following points:

• Condition of a variable film type resistor. If there are breakdowns or scuffs on the tracks of the DPDZ device, the electronic unit Control receives erroneous parameters.
• Does the normal opening of the contacts of the XX occurs.

There were ate based on the results of the check, after all, it was possible to identify the fact of the fault, and you replaced the throttle sensor, then in the additional adjustment of the device (after the installation is complete) there is no need. Zero mark for the part is idle when the throttle is blocked. Consequently, it is not necessary to attract a specialist to work - you can cope on your own.

WHY DPDZ sensor can break?

It is important to understand that it can cause damage to the sensor under consideration. Of course, it is impossible to completely eliminate the malfunction, but it is quite realistic to reduce the problems of minimum.

Causes of malfunction of DPDZ:

• The slider loses contact with the resistive layer. The reason is a breakdown of the tip, which is why there are styles on the substrate, and then fail and the remaining items. At the same time, the sensor can continue to continue to work (albeit with failures) - until the moment until the resistive layer is erected at all. As a result, the core breaks finally. It is not always possible to notice such a malfunction to DPDZ, so the problem may continue to disguise for other troubles. For example, a car owner may have suspicion of low quality fuel or other problems.
• The linear increase in the outlet voltage does not occur. This is possible when the device is erased to base, at the point of the start of the movement of the slider.

Note that with such a malfunction, additional signals indicating the presence of problems of the throttle sensor is not provided. Consequently, the only thing that the auto owner should navigate - the stability of the motor in various modes.

One of the components of the schemes of various electronic and electrical appliances is choke. Chokes call inductor inductor, which when working in electrical circuits Limits the conductivity for alternating current and freely skips the current constant. This throttle property is used to smooth the variable component of currents. The throttle check is carried out by a multimeter or a special tester.

Purpose and device

In some devices, chokes are set to skip the pulse currents of a specific frequency range. This range depends on the design of the choke, that is, from the wire used in the coil, its cross section, the number of turns, the presence of the core and the material from which it is manufactured.

Structurally, a throttle is wound on a core insulated wire. The core can be metallic scored from insulated plates or ferrite. Sometimes the throttle can be performed without a core. In this case, a ceramic or plastic frame for wire is used.

The throttle is present in the carburetor. It regulates the supply of a combustible mixture, representing a potentiometer. To check the throttle valve sensor in the car, determine the correspondence of the input voltage of the device by the flaps.

In the multimeter, the transverse mode is set. The sensor connector contacts are connected to the multimeter shoes and create the visibility of the movement of the flap (fingers). At the same time check how the sensor responds in the extreme positions of the flap. There must be a clean signal without wheezing.

In lamps

In the lamps provided for the use of daylight lamps, in addition to the lamps themselves, components such as the starter and choke are used.

The starter, as follows from the name, starts the glow process in the lamp, and then does not participate in the process. The throttle performs the functions of the current and voltage stabilizer during the entire lamp glow period.

If the choke is faulty, the lamp does not burn, or it is not stable, the luminescence of it is inhomogeneously along the entire length, inside areas can appear with a brighter lumulation moving from one electrode of the lamp to another. Sometimes you can notice the effect of flickering light.

The lamp with a faulty throttle may not light up the first time, and the starter will be repeatedly turned on until finally the glow process will not start. As a result, in places in the installation of spirals, darkening will appear on the flask. This is due to the fact that the spirals work for a longer time than installed for normal launch.

Check in lamps

The verification of the throttle must be made if one of the above phenomena is observed during the operation of the daylight lamp, as well as if the appearance of the characteristic smell of tight insulation, the appearance of sounds uncharacteristic for the operation of the device, as well as in the event that the lamp does not turn on.

Before checking the choke lamps, the lamp itself is checked and the starter.

The throttle malfunction can be in the cliff or burnout of the coil wire or interstitious closure caused by a breakdown or burning isolation.

Both faults may occur either due to a long time to use the device, or as a result of any mechanical impact. It is possible to burn the wires of the coil as a result of the supply of a larger current on it than the maximum, which is calculated by the throttle.

In the event of a break or burnout of the wire, you can identify a malfunction with a conventional tester or multimeter. Due to the fact that the throttle passes d.C.By closing the chain of the tester through the coil, on the luminescence of the control lamp or its absence, you can understand whether there is a break or not.

If when measuring a multimeter, the resistance is infinite, the coil wire breaks.

Checking inter-touch closure

In the case of an inter-touch closure, check the result tester will not give. In this case, you need to know how to check the throttle using a multimeter.

Mixless closure takes place with the direct galvanic contact of two turns or at contact turns with a metal core. Obviously, in this case, the coil resistance decreases.

A rare case is possible when the measurement of the resistance of the coil will not give a reliable picture of its state. This can happen when the closed and interstitious closure simultaneously.

In this case, the intersless closure may be parallel to the cliff, and several turns simply will not participate in the dimension. Competitive, it would seem, the choke will work incorrectly.

To check the coil for the presence of an inter-touch closure, an analog multimeter in Milliammeter mode must be used as part of the device assembled on two transistors.

The instrument diagram is shown in the figure.

The device itself is a low frequency generator. When assembling the scheme, any transistors from the MP39-MP42 line (amplification coefficient 40-50) are used.

Diodes can be used type D1 or D2 with any index. Resistors are used by any type, calculated on the power of at least 0.12 W. The device is powered by a DC source, voltage of 7-9 V.

Sequence of action

The verification procedure is as follows:

1. the VK toggle switch is included. In this case, the arrow of the multimeter must deviate up to the middle of the scale;
2. depending on the inductance of the coil, the position of the variable resistor R5 engine is set. The left position corresponds to the smaller, and the right - greater inductance. When checking coils with an inductance of less than 15 mp, it is necessary to additionally press the KN2 button;
3. the LX terminals connect the throttle conclusions and the contact KN1 button is closed. At the same time, if there are no turns in the winding, short-circuited, the arrow of the multimeter must deviate in the direction of large values \u200b\u200bor slightly deviate towards the smaller. If there is at least one closure in the winding between the turns, the arrow returns to zero.

Sometimes the cause of the coil malfunction can be a collapsed or damaged core. The material from which the core is performed, its size and position relative to the coil, affect inductance.

Check inductance

The presence in the arsenal of the multimeter of such a useful function as the measurement of the inductance of coils will be useful for checking the correspondence of the throttle characteristics declared in the reference literature. The function is present only in some models of digital multimeters.

To use this feature, you must configure the multimeter on. Contacts of probe are attached to the conclusions of the coil. When the first measurement, the multimeter is set to the largest range of measurements, and then the range decreases to obtain sufficient accuracy.

When carrying out all the measurements, it is important to avoid touching the contacts with the hands on which certain parameters are measured, otherwise the conductivity of the human body can change the instrument readings.

Checking the throttle sensor The potentiometric type consists in checking the compliance of the output voltage of DPDZ actual position of the throttle in the entire range of possible.

And so what to start diagnostics and how to check the throttle sensor? The answer to this question is just a visual video. In this case, the potentiometric type DPDZ test with the built-in sensor of the end position is considered, on which it has not 3 outputs, but the 4th. But first of all, you need to figure out what is this DDZ. In essence, this is a potentiometer, the axis of which is rigidly connected with the axis of the throttle. The supply conclusions of the DZ sensor, as a rule, is fed 5V and "Mass", and the movable contact is alarm. ECU is used to calculate the number of the desired fuel volume into the current mode of operation and calculating the ignition advance angle.

Throttle position sensor check It begins with connecting the contacts of the DPDZ connector to the multimeter (pre-exhibiting the "transverse" mode). After that, imitating the movement of the throttle, check the sensor reaction in the extreme positions of the flap. Not depending on how many contacts 3 or 4 the procedure is the same. Warms talk about a malfunction!

But to make sure of your assumptions you can make a control check for the resistance of the sensor (the exact data you need to look at the manual of your car, but in general, it is up to 10 com).

It is worth noting that such a check can also be carried out and without removing the sensor with the throttle. To do this, from the sensor, disconnect the block and turn on the ignition, then the "+" multimeter connect to the supply of the pads of the wiring harness, and "-" on the motor weight. On the dial, 4.8-5.2 V should be lit. After turning off the ignition, check the resistance as the same method, as with the removed DPDZ. When the flap is closed should show less resistance, and when it is completely open, it is significantly more (the exact data depend on those. Sensor characteristics). For example, the throttle sensor of the VAZ throttle must be within 0.9-1.2 kΩ (the flap is closed) and 2.3-2.7 kΩ (the flap is open). Not to enter the values \u200b\u200bin the gap speaks about the malfunction of the throttle sensor.

In order to check the throttle position sensor with electronic pedal First you need to press the gas pedal until it stops, and then remove the readings by a multimeter mode in the Voltmeter mode. The readings of the first and second sensor in the amount should correspond to 5 volts - this is a reference indicator, it means that the throttle valve is normal.

Next, we measure the voltage of the sensors separately. The position of the gas pedal №1 and the gas pedal position sensor No. 2, with a fully pressed gas pedal, must correspond to 4.2 volts and 2.1 volts, respectively. And thus, if the testimony of the first sensor on the voltage on the second should it turn out that the difference between them is exactly twice, that is, 2.1. Such a regularity will indicate that in the position of the ignition position "Inclusive" when the gas pedal is positioned to the floor, our gas pedal will show the correct meaning, which means it is good. In the event of a malfunction of the DPDZ, the electronic throttle node or gas pedal will pop up error P2138. - Invalid ratio of the voltage "D" / "E" of the sensor of the position of the throttle valve or gas pedal. The appearance of "Check" with such a code is the main reason for detailed diagnosis electronic pedals Gas.

The second stage of verification may be the work of the pedal when pressed. To do this, it is necessary to measure the resistance between the two adjacent tracks (on the disassembled pedal visually). When moving the gas pedal, resistance between contacts should change smoothly. Changes with jumps indicates that gas pedal should be replaced.

VAZ-2114 is an advanced version of "nines". Almost the same motors were installed on this "Lada". However, the main difference is the injection injection. In the 14th "Lade" completely moved away from old carburetors. but new system required the presence of new sensors. In order for the motor to work properly, dozens of sensors operate in the design. They read the signals and transmit them to the electronic unit. Among such signals, it is worth noting the temperature of the coolant, oil pressure, concentration of CO exhaust gases, the position of the crankshaft and air flow.

But there is another element without which it is impossible stable work Engine. This is a throttle position sensor VAZ-2114 (abbreviated DPDZ). What is this element, why does he fail and how to check it? Consider in our today's article.

Characteristic

DPDZ is a device that serves to convert the angular position of the air damper into a constant current. Such an element is installed on all vehicles with fuel injection. Information from the transmission valve sensor goes to the collector. DPDZ itself can be of different types - film or magnetic (contactless). It is arranged in the same way as the air valve. When the element is open, the pressure in the system is similar to atmospheric. But as soon as the item closes, the pressure is reduced inside - a vacuum is formed.

In the design of the electronic throttle position sensor, the VAZ-2114 is a variable and permanent resistor. The resistance of both is about eight ohms. But the outlet voltage can change. This indicator depends on the position of the throttle itself. For these processes also monitors a special controller. Depending on the received signals from DPDZ, the system regulates the amount of air and fuel concentration in the mixture. If the slightest malfunction of the throttle position sensor is fault, the VAZ-2114 will work incorrectly. The engine will get too much fuel. In both cases, the motor will suffer significant loads, its elasticity is lost.

Where is installed?

This element is in the throttle node.

If we talk more specifically, the sensor is fixed on the flap housing (connected to its axis), next to the idling regulator.

Resource

How much does the throttle position sensor serve in the VAZ-2114 car? Replacing this element does not require the next 50 thousand kilometers. It is such a service life on average at DPDZ on a vase. But since the mileage of most cars of this model has long exceeded a hundred, the owners often face element faults. How to determine what the item is inoperable? Tell me below.

Signs

There are several symptoms that talk about the malfunction of this item:

• High revs on idling. Also, such a malfunction occurs with the non-working XX regulator. In both cases, the flap opens at a much greater angle. Because of this, a lot of oxygen comes into the chamber. And the more air, the faster the mixture will be burned. Accordingly, due to this, the revolutions are incontrolled.
• Reduced engine power. This may occur due to improper preparation of the working mixture. It contains more oxygen than it is supposed. As a result, the motor lacks energy to develop a torque. Along with this, the accelerating dynamics of the car is noticeably falling.
• Junks when you click on the accelerator pedal. The essence of the problem is simple - at the time of pressing the gas in the cylinders more air flows. And since its concentration and so higher norms, there are failures and a motor cannot enter normal revolutions.
• Spontaneous engine shutdown on the go. This also occurs due to the large concentration of air. In the combustion chamber, there is not enough fuel to produce the workforce of the piston. Because of this, the motor Troit and simply stalls.

The reasons

Ranee We considered the reasons for incorrect work power aggregate. As you can see, the failures occur due to improper concentration of air in the mixture.

But for what reasons the throttle position sensor itself fails to the VAZ-2114? Among the causes of malfunctions, DPDs should be allocated:

• Burnt contacts. Moving sensor contact When opening the flap begins to move, contacting the resistive field. With long-term operation, the field is destroyed and contact disappears. The signal can no longer be transmitted to the controller, which is why the system cannot work normally.
• Oxidation of contacts. And if in the first case it is not to restore them, then in this situation you can try to return the performance sensor. So, to restore the oxidized contacts splash the VD lubrication to the block and into the space under the lid. This lubricant contains anti-corrosion additives that are corrosive rust. At half past cases, it helps to return the life sensor.
• Wearing a substrate DPDZ. However, it is present in the design only if a special spraying consisting of a resistive layer is provided.
• Incomplete closure. In this case, you can direct the supphyl the seat of the VAZ-2114 throttle position sensor, and the motor will re-operate.

Diagnostics

It can be done with your own hands. However, checking the throttle position sensor VAZ-2114 should be carried out using a special instrument - multimeter. It must be translated into the voltage measurement mode and connect to the ground. Red dipstick should connect to the positive conclusion "A". It is located on the DPDZ connector housing. Please note that measurements are made when the ignition is turned on. Otherwise, the value will always be zero. Turning on the ignition, we look at the results. The output voltage should be five volts. An insignificant error is allowed in the region of 0.3 V. If the voltage is less than 4.7 V, this item is faulty and is replaced.

If the multimeter showed zero with the ignition turned on, it may have occurred in the chain and the voltage simply does not reach the sensor. But if everything is in order with the wires, it means that the controller of the throttle position of the VAZ-2114 is failed. Signs of its malfunction - complete absence of voltage at the conclusions of DPDZ.

Diagnostics: Method number 2

You can also check the operation of the item without turning off the connector from it. To do this, you will need the same multimeter. We will check the presence of a voltage to the sensor. When the ignition is turned on, a smooth voltage increase from 0.8 to 4 V. will be noticeable

At the same time, you need to rotate the plastic air damper sector. The sensor connector must be connected. A voltage is checked by piercing the wire with a dipstick multimeter.

Method number 3.

We switch our measuring instrument to an ohmmeter mode. Next, turn off the connector from the sensor.

After you connect the probe multimeter to any moving and stationary contact. If the sector is rotated, the arrow of the ometer will move smoothly. The presence of sharp jumps arrow indicates a malfunction of DPDZ.

Which to choose?

Please note that VAZ-2114 throttle position sensors are not subject to repair. This element changes entirely by car. There are several manufacturers of DPDS for "Lada-Samara-2":

• "ROBMASH".
• "AutoElectrician".
• "Omega".

The latter is installed on "Lada" from the plant. It serves long enough. When choosing, you need to pay attention to non-contact elements. They cost about 600-900 rubles.

But serve for a very long time - reviews. Do not buy resistive sensors. They are unreliable and quickly fail. As for the sensor of the throttle position of the VAZ-2114 "Kaluga" (the same "auto electrician"), it is non-contact and sold at a price of a thousand rubles. Reviews about it positive. The only drawback is a high price. But it is fully justified by the resource of this sensor model.

Replacement

This element changes simply enough. You need to open the hood and determine the location of the sensor.

Next, with a screwdriver, squeeze a plastic latch and remove the block with wires. After that, unscrew the sensor mounting bolts to the throttle housing. Together with the old DPDZ, the gasket is removed. In her place is installed new, from the foam rubber. Then the new sensor itself is mounted on it. It is attached on the same two bolts. You should twist tightly in order to exclude extra vibration (From them, the item may incorrectly work). After that, connect the block with wires and make the first launch. Motor operation must stabilize.
