I decided to tell everyone about a little-known method of testing the dashboard and identifying errors without an on-board computer. The method is primitive because They developed it at Auto VAZ, but still.
Instructions: Hold down the odometer button, turn the ignition key to the first position, release the button. The arrows start moving, press again, release, see the firmware version. And the third time they pressed, released, saw the error code (if there is one) on the video code: 8. To reset the error code, press and hold the button until the number 0 appears.
1 Microprocessor error 2 Fuel gauge sensor circuit error 4 High voltage 8 Low voltage 12 Indicator lamp diagnostic circuit faulty 13 No oxygen sensor/LAMDA probe signal 14 Coolant temperature sensor signal high 15 Coolant temperature sensor signal low 16 On-board voltage too high network 17 Low voltage on-board network 19 Incorrect crankshaft position sensor signal 21 High signal level of the throttle position sensor 22 Low level of the throttle position sensor signal 23 High level of the intake air temperature sensor signal 24 No signal from the vehicle speed sensor 25 Low level of the intake temperature sensor signal air flow 27 CO potentiometer signal high 28 CO potentiometer signal low 33 MAF sensor signal high 34 MAF sensor signal low 35 Idle speed deviation 41 Phase sensor signal incorrect 42 Electronic ignition control circuit malfunction 43 Signal incorrect knock sensor 44 Lean mixture 45 Rich mixture 49 Vacuum loss diagnostics 51 PROM error 52 RAM error 53 No CO potentiometer sensor signal 54 No octane corrector sensor signal 55 Leaning at high engine load 61 Oxygen sensor/LAMDA probe degradation
Errors persist until they are reset manually! Also mistakes add up! Those. If you have errors 8 and 14, the display will show error 22
Owning a domestically produced car of yesteryear necessarily implies carrying out independent repairs of the car’s components and assemblies. In the case of the VAZ 2114, it is quite easy to carry out repairs yourself, because The design of the machine and all its main “sores” have long been known. For young and inexperienced car enthusiasts, there are a lot of sources with detailed explanations and instructions for repairing all components of the 2114 model. Also, the injection versions of the model provide self-diagnosis of the VAZ 2114, which displays error codes present in the car. In this article we will analyze all types of errors that a car detects, and also describe the process of self-diagnosis.
Self-diagnosis of the VAZ 2114 model does not require serious knowledge in the field of electronics and mechanics, because To start it, you just need to take a couple of steps:
- Hold down the odometer button (on the dashboard under the speedometer scale);
- Without releasing the pressed button, turn the key in the ignition switch to the first position;
- Next, you will see that the self-diagnosis of the arrows on the dashboard has started. At this time, press the odometer button two more times (after the first press, the firmware version will be displayed).
- After displaying the firmware and pressing the key again, an error code will be displayed. To instantly reset it, just hold down the button for a while.
Important! It is worth clarifying that this method of automatic diagnostics is only possible on VDO dashboards. In other cases, errors are detected using special programs and scanners.
Error codes are displayed on the display, where the vehicle's daily mileage is usually located. To decipher the codes, you should familiarize yourself with the entire list of problems that are detected through checking using this method.
Despite all the primitiveness of this method of identifying problems in the operation of a machine, self-diagnosis allows you to determine the main reasons for the lightning of the “check”, and also displays errors in the on-board network. An extensive list of self-diagnosis errors for the VAZ 2114 includes the ability to display error codes in the operation of electrical systems, crankshaft sensor, air flow, during the formation of the air-fuel mixture, etc.
| Error code | Decoding |
| 1 | problems with the central processor |
| 2 | problems in the gasoline level sensor circuit |
| 4 | high voltage |
| 8 | low voltage |
| 12 | warning light circuit |
| 13 | no connection with the oxygen sensor (lambda probe) |
| 14 | high signal from the antifreeze temperature sensor |
| 15 | low signal from the antifreeze temperature sensor |
| 16 | overvoltage in the on-board network |
| 17 | low voltage in BS |
| 19 | incorrect crankshaft sensor readings |
| 21/22 | high/low TPS signal |
| 23 | incoming air sensor signal is too high (code 25 – low value) |
| 24 | there is no signal from the vehicle speed sensor; |
| 27/28 | high/low potentiometer signal |
| 33/34 | high/low signal from mass air flow sensor |
| 35 | incorrect idle speed |
| 41 | incorrect signal from the phase sensor |
| 42 | problem in the ignition system circuit |
| 43 | malfunction of the knock sensor |
| 44 | poor air-fuel mixture |
| 45 | enriched air-fuel mixture |
| 49 | – defects in the vacuum system |
| 51 | programmable read only memory error |
| 52 | RAM error |
| 53 | no signal from potentiometer |
| 54 | no signal from octane corrector |
| 55 | lean mixture under engine load |
| 61 | problems with the lambda probe (degradation) |
Note that self-diagnosis errors on the VAZ 2114 can be cumulative when displayed. For example, high voltage in the BS (4) and a problem with the control lamp (12) will be displayed on the panel as 16. After all the faults have been eliminated, notes about the problems are stored in the computer memory, so upon completion of the repair procedures you need to reset everything to 0. This is done long holding the odometer button. Summing up error codes is the main reason why it will not be possible to identify a problem with 100% confidence on a VAZ 2114. As for eliminating all the reasons that cause the listed combinations of errors, you can always contact service specialists. There are many nuances in this self-diagnosis method, so you should not base your guesses about breakdowns on the basis of the troubleshooting performed. If self-diagnosis on the VAZ 2114 is not possible due to the dashboard of another company (not VDO), then you can purchase a special OBD scanner to connect it to a laptop or mobile phone.
Further, if you have the software and the appropriate version of the ECU, you will have access to all possible indications and malfunctions of the machine being diagnosed. It is clear that this method is more expensive, but it allows you to see a broader picture. The location of the plug for the OBD scanner is shown in the photo below.
Car self-diagnosis
The self-diagnosis procedure is performed as follows:
- When the ignition is turned off, the odometer daily mileage reset button is pressed.
- Then the key is installed in the switch and turned. It is rotated to the first position to activate the ignition system.
- After turning the key, the mileage reset button is released. The arrows on the speedometer, tachometer, fuel and engine temperature gauge will begin to move from the minimum value to the maximum.
- The daily mileage reset button is pressed again. An inscription with the board firmware version will be displayed on the instrument cluster.
- The button is pressed again. After this, VAZ 2114 error codes will begin to be displayed on the dashboard screen.
Deciphering the VAZ 2114 self-diagnosis error codes will help you identify vehicle malfunctions and understand what actions need to be taken.
The channel “Your Own Mechanic” talked about carrying out a self-diagnosis procedure on a VAZ 2114 car.
Resetting the "Check Engine" error
- The ignition is activated, but the car engine does not start.
- The engine compartment of the car opens. Use a wrench to loosen the bolt that secures the terminal clamp to the negative terminal of the battery.
- Then you need to wait about a minute, then the battery terminal must be connected back.
- The engine compartment of the car is closed and the ignition is turned off.
- Then the power unit of the machine is started.
If the Check indicator continues to light, then you need to wait a while, it should disappear on its own. If the Check Engine light does not disappear from the dashboard, we can conclude that troubleshooting has not been performed.
User Ravil Shayakhmetov showed the procedure for independently removing the Check error from the dashboard of a VAZ car.
How can I reset errors myself?
To delete the data remaining in the memory of the control unit, a repeated self-diagnosis of all systems is performed. Once error codes are displayed, the information is recorded. Pressing the daily mileage reset button again will delete the fault data from the ECU memory.
The Glaz Szalg channel spoke in detail about resetting errors in VAZ cars.

Important!
Only the most popular error codes for the dashboard of the VAZ 2114 and similar models are listed here. There are other indices, but due to their low prevalence they are not mentioned.
What are the errors that indicate a faulty phase sensor?
There are two error codes that indicate a faulty phase sensor:
- 0340;
- 0343.
Symptoms of problems will be as follows:
- the car moves jerkily, and the driving speed noticeably decreases;
- the power of the power unit decreases, in some cases the car cannot pick up speed above 60 km/h;
- the engine stalls when the gear is in neutral, for example, at traffic lights;
- the dynamics of the power unit decreases, shocks during acceleration, pops in the exhaust system;
- The ignition spark may completely disappear, as a result of which the car engine will not start.
Error code 0340
Error code 0340 indicates a faulty phase controller. The camshaft sensor needs to be checked for functionality. Sometimes error 0340 is associated with problems with the crankshaft position controller. The malfunction may be caused by the fact that the timing belt (gas distribution mechanism) has slipped by one tooth.
Error code 0343
The channel “In Sandro’s Garage” talked about troubleshooting a problem related to the operation of the camshaft sensor.
Diagnostics using special equipment
If you resort to a verification method using special equipment, you will need a computer on which diagnostic software is pre-installed.
The necessary software (programs) is downloaded from the Internet:
To connect to the diagnostic output, you will need a wire with an adapter. One end of the cable is connected to the header, and the other to the USB input on the computer or laptop.
For diagnostics, perform the following steps:
- A detailed inspection of the car is carried out. The car owner checks the availability of consumables. This can be brake fluid, engine and transmission oil, and antifreeze.
- The diagnostic output is searched for and a computer is connected to it. The ignition system in the car is first activated by turning the key in the lock to the appropriate position. The engine should not start. If there is a special scanner, then instead of a computer, this equipment is connected to the diagnostic connector.
- Then the diagnostic software is launched. Depending on the developer, the utility interface may differ. In many programs, when launched, graphs or technical parameters of the car with numbers appear.
- The car begins checking for errors; to do this, press the corresponding button in the program. At the end of testing, the utility displays error codes.
How to fix the problem
After diagnosis, the problem should be repaired. When reading a signal, it is necessary to check the circuit and devices following it. The most accurate method is to replace the damaged part with a known good one (new). This will eliminate the possibility of incorrect repairs. If the device is in working condition, the lines are checked; usually a primitive test is sufficient. However, if the control unit or relay fails, you will need a special tester and the ability to use it.
Separately, it is necessary to take into account that factory terminals and blocks become loose and oxidize over time. If the contact on the hitch deteriorates, the on-board computer or laptop program will say that the part is damaged, even if it is not.
You can prevent this from happening in the following way.
- Check the condition of the connectors once every 5000 km. The pads should sit in place tightly, without play. If necessary, elements must be replaced with new ones.
- Check plug connectors two to three times a year for oxidation. Oxides reduce the flow of electricity through on-board wiring, which leads to incorrect display of information.
- Experts recommend purchasing and using oil for electrical terminals. The liquid is similar in composition to transformer lubricants. The formula prevents water and oxygen from reaching metals, which prevents them from rusting.
Important!
You can diagnose VAZ 2114 error codes on the instrument panel and ECU yourself, only if you understand the essence of the process. If you don’t have confidence in your own abilities, it is recommended to contact a qualified technician.
If you have the appropriate knowledge and the necessary equipment, you can find and correctly decipher the error codes of the VAZ 2115 injector and other elements yourself. Due to the simplicity of the car's electrical circuit, the user does not require deep knowledge of mechanics or electronics.
Car self-diagnosis
The self-diagnosis procedure is performed as follows:
- When the ignition is turned off, the odometer daily mileage reset button is pressed.
- Then the key is installed in the switch and turned. It is rotated to the first position to activate the ignition system.
- After turning the key, the mileage reset button is released. The arrows on the speedometer, tachometer, fuel and engine temperature gauge will begin to move from the minimum value to the maximum.
- The daily mileage reset button is pressed again. An inscription with the board firmware version will be displayed on the instrument cluster.
- The button is pressed again. After this, VAZ 2114 error codes will begin to be displayed on the dashboard screen.

The Glaz Szalg channel spoke in detail about resetting errors in VAZ cars.
Recovery
Is it possible to restore a broken sensor? This can be done only in one case - if the cause of the malfunction is poor contact and the sensor itself is working normally. You can also try removing the carbon deposits inside. But to do this, you need to take the sensor out and lower it into an aggressive environment (white spirit or gasoline). Please note: do not use sandpaper, needle files or other rough objects for cleaning. To avoid damaging the tip, use a soft cloth soaked in solvent. By treating the sensitive element with white spirit, you can restore the functionality of the sensor. But it is not a fact that after cleaning it will take accurate measurements. Ideally, this element should be changed entirely. Fortunately, the operation is simple, you can do it yourself. We’ll tell you exactly how below.
What are the errors that indicate a faulty phase sensor?
There are two error codes that indicate a faulty phase sensor:
- 0340;

Let's sum it up
If you own a VAZ car, then you are familiar with the incorrect operation of on-board computers. Often errors are issued for no reason at all, but they interfere with the normal operation of the power unit. Therefore, the best way to protect against most unforeseen situations with on-board computers is to change the software.
In this process, it is important to install the official version of the program without risking the viability of your car. There are known cases when unofficial software killed the entire electrical system of a car, sending incomprehensible commands and signals to all sensors of the on-board system. Also, the setup should be done by a professional. Have you had any problems with VAZ on-board computers?
Video
The Garage channel, using the VAZ 2115 as an example, showed the procedure for checking a car using a computer; in the case of the 2114 model, this operation is performed identically.
After self-diagnosis of errors and elimination of their causes on a carburetor or injection engine, a malfunction message may remain on the standard panel. If the problem has been deleted, this means that the code combination remains in memory. We'll look at the description of the faults below, and now we'll tell you how to remove the code from memory. To remove it after testing the device, when VAZ 2114 errors appear, the codes themselves must be written down. After this, the daily mileage reset button is pressed again, this will clear the fault from the control unit’s memory.
Resetting the "Check Engine" error
The "Check Engine" indicator indicates a problem with the engine.
How to reset the fault code:
- First, turn on the ignition; you do not need to start the car engine.
- Then open the hood. Use a wrench to loosen the bolt on the negative terminal of the battery.
- Wait about one minute, after which the battery terminal must be replaced.
- Close the hood and turn off the ignition.
- After that, turn it on again and start the car engine. If the check remains, it should go out on its own after some time. If the instructions given did not work and the solution did not help, then you need to look for the cause of the problem and fix it.
Meaning and interpretation of error codes
To read the faults, first consider the list with a table of UEr errors that self-diagnosis produces (the author of the video is Ivan Vasilyevich).
| Number | Description |
| 1 | Problems with the functioning of the microprocessor. |
| 2 | Self-diagnosis of the VAZ 2114 detected problems with the electrical wiring of the fuel level indicator controller. The signal level coming from the sensor may be too high or low. It is necessary to test the controller and check the wiring. |

These codes can add up; if you see the number 6, this may indicate errors 2 and 4, or if the number 9 is displayed, errors 1 and 8.
In order to immediately read and decipher problems when diagnosing, it is advisable to download and always carry with you a printout with a description. When diagnosing using a computer, codes on engine 21124 may differ depending on the car model. To read the codes, you need to know how they are supposed to be deciphered. Errors must be reset after they have been deleted (the video was filmed and published by the KV Avtoservis channel).
| Number | Decoding |
| p0102, p0103 | An incorrect pulse is supplied from the mass air flow sensor controller. This means you need to check the wiring. |
| p0112, p0113 | 112 or 113 - the incoming air temperature sensor needs to be replaced. |
| p0115-p0118 | Errors from 0115 to 0118 - the antifreeze controller sends an incorrect impulse. There may be problems with the wiring or the sensor itself. |
| p0122, p0123 | TPDZ. The controller is sending an incorrect signal. If the wiring is damaged, interference may occur. |
| p0130, p0131 | The lambda probe requires diagnostics and replacement. |
| p0135-p0138 | Error 0135 and higher - the lambda probe heating regulator needs to be replaced. |
| p0030 | The ECU reports problems in the electrical circuit in the area from the lambda probe heater to the converter. If error p0030 occurs, you need to test the electrical circuit and the sensors themselves. |
| p0036 | P0036 - a break in the wiring of the heating device DK-2 was detected. |
| p0300, p0302 | When codes 300 and 302 appear, the ECU reports a misfire. |
| p0301 | Gaps were detected in the cylinders of the power unit. Compression needs to be checked. |
| p0325 | The knock sensor is not working correctly. In particular, we are talking about a break in the connection wiring. |
| p0335, p0336 | P0036 error VAZ 2114 or 10335 - the DPKV has failed or its connection circuit is damaged. If the wiring is intact, then the sensor is replaced. |
| p0340 | Phase sensor malfunction. |
| p0341 | Error VAZ 2114 0341 means a problem with the camshaft controller. |
| p0342, p0343 | Problems with the phase controller. With such an error, detonation of the car engine is possible. Most likely, only replacement will solve the problem. |
| p0346 | P0346 VAZ error - also a problem with the phase regulator. |
| p0363 | P0363 - misfire of the combustible mixture was detected. In cylinders that refuse to work, the fuel supply is cut off. |

| p1513 | There is a short circuit in the wiring of the idle speed sensor. It is necessary to test the electrical circuit and check the contacts. |
| p1602 | Failures in the voltage supply to the vehicle's electrical network are detected. |
| p0560 | Incorrect voltage level in the on-board network. This parameter can be overestimated or underestimated. The car battery, as well as the generator unit, are subject to testing. |
| p1514, p0511 | The appearance of these errors indicates a problem with a break or short circuit in the IAC (idle speed regulator) wiring. First of all, diagnose the sensor contacts, and then test the circuit, if possible. The sensor itself may also be damaged. |
| p1303 | P1303 - A detected misfire of the air-fuel mixture in the third cylinder is reported. The malfunction must be corrected as quickly as possible, since it can be critical for the neutralizer. |
| p1578 | Throttle valve malfunction. Literally, the problem stands for “zero adaptation parameter is outside the permissible value.” There are several options to solve the problem. The first thing you need to do is clean the throttle valve. If this does not help, then the throttle is adapted. To do this, you need to activate the ignition, and then start the engine after 40 seconds. Alternatively, you can test and tighten the contact terminals on the throttle. |

| p2187 | Lean mixture in internal combustion engine cylinders. You need to do a detailed diagnosis of the problem. |
Diagnostics using special equipment
1. Diagnostic connector
2. Connecting a wire with an adapter to the diagnostic socket
3. Connecting the wire to the computer
4. Launching software for testing
The diagnostic process using special equipment consists of checking the car using a laptop. To connect to the diagnostic connector you will need a cable with an adapter. Using this cable, we connect the computer to the connector via USB output. For testing you will also need software; the power of the computer used is not important. There are many versions of different testing programs on the Internet.
Diagnostics is performed as follows:
