How to drive a fuel-injected car correctly
Trip computer VAZ 2110
You can give some important tips for operating a car with an injector:
- Maintenance must be carried out on time.
- The vehicle should only be fueled with the recommended fuel from the manufacturer.
- Sound insulation is necessary, as the injector is quite loud.
- The body should be treated with anticorrosive.
Note: processing is necessary to prevent the body from corroding.
Fault codes for VAZ 2110 2111 2112.
Here we provide only brief information on diagnosing the injection system using the CHECK ENGINE warning lamp. Diagnostics using special instruments and diagnostic cards are described in detail in separate repair manuals for distributed fuel injection systems.
The controller continuously performs self-diagnosis on certain control functions. The controller's language for indicating the source of a malfunction is diagnostic codes. Codes are two-digit numbers ranging from 12 to 61. For different controllers, fault codes may differ slightly from each other. The table “Fault codes for the controller of the “January-4” type” presents a breakdown of the fault codes for the controller of the “January-4” type for the distributed fuel injection system without feedback and with domestic components.
When a malfunction is detected by the controller, the code is stored in memory and the “CHECK ENGINE” indicator light turns on. This does not mean that the engine should be stopped immediately, but the reason for the warning light to come on should be discovered as soon as possible.

Diagnostics
There are two ways to set error codes for VAZ 2114 injector 8 valves. However, each method has unique advantages and disadvantages.
Self-diagnosis of VAZ 2114: error codes and their interpretation
The self-diagnosis method does not require the driver to have complex instruments or additional units. To complete the procedure, the car itself is enough.
The standard sequence of actions looks like this.
- Press the odometer reset button.
- Turn the ignition key to position No. 1 (turn on the on-board electrics).
- Release the mileage reset button. After this, the instrument arrows will make a full revolution and return to their place.
- Press the reset button a second time and release. The command displays the firmware version indicator.
- Repeat step No. 4 - this will display error codes on the on-board computer.
If the sequence of actions is performed correctly, all indicators will light up and the display will show a two-digit fault code.
Note!
A failure signal may be a lack of response from the indicator. In this case, it is necessary to check the circuit coming from the device.
The most common error codes for the VAZ 2114 panel, occurring in 90% of cases:
- 1 – microprocessor failure, flashing required;
- 2 – error code 2 VAZ 2114 indicates that there is an interruption or disruption in the wiring of the float sensor inside the gas tank;
- 4 – electrical wiring short circuit, voltage limit exceeded;
- 8 – error code 8 on the VAZ 2114 indicates a drop in voltage in the network, the battery may have run out;
- 12 – in the VAZ 2114, error code 12 indicates that the warning lamp is not functioning properly;
- 13 – open circuit of the oxygen sensor;
- 14 – error code 14 on the VAZ 2114 warns the driver that the engine has overheated or the antifreeze temperature sensor has shorted;
- 15 – short circuit or DTOZh has failed;
- 16 – exceeding the permissible voltage limit of the on-board network;
- 17 – BS voltage has dropped critically, battery discharge is allowed;
- 19 – DPKV does not respond or there is a short circuit on the line;
- 21-22 – incorrect response of the TPS, possible short circuit or wiring break;
- 23/25 – short circuit of the throttle position sensor;
- 24 – speedometer failure, power cords may be broken;
- 27/28 – CO sensor worn out or broken;
- 33/34 – problems with the mass air flow sensor, possible power loss or short circuit;
- 35 – IAC sensor has failed, can only be treated by complete replacement;
- 41 – incorrect phase distribution covered or shorted;
- 42 – the circuit has failed or the wires of the electronic ignition unit have been broken;
- 43 – mixture detonation sensor is faulty;
- 44/45 – there is a violation of the fuel supply to the engine, the system may trip, jerks appear during acceleration, and it picks up speed poorly;
- 51 – ROM is acting up;
- 52 – similar for RAM;
- 53 – potentiometer failure;
- 54 – break in wiring for octane corrector;
- 55 – excessive leanness of the mixture during acceleration;
- 61 – interruptions in the operation of the lambda probe.
In some cases, errors may be superimposed on each other if the failure is similar. For example, if errors 1 and 4 intersect, the panel will indicate "5".
It is important to know that after viewing, VAZ 2114/2115 error codes do not disappear on their own after repairs are performed. They need to be forced reset. To complete the work you will need a simple sequence of actions:
- turn on the car ignition;
- remove the terminals from the battery;
- wait 20-30 seconds;
- return the clamps to their place.
This also needs to be done if you are planning a trip to a service station. Having discovered the instructions from the on-board computer, the technicians will correct these problems, which will definitely be more expensive.
The disadvantages of an independent procedure include the low accuracy of the data. On-board diagnostics only show the general direction vector where the fault should be looked for.
Check using diagnostic equipment
You can identify error codes for VAZ 2115 and 2114 using a laptop with a special program. The tool is connected to the vehicle's test socket through a set of adapters. The wizard configures the software, and after diagnostics, one or more faults will be displayed on the computer screen in the form of a five-digit code.
The first part is the letter:
- B – damage to body panels;
- C – chassis or suspension malfunction;
- P – electrical, engine or transmission disorder;
- U – damage to the terminal for information exchange.
The second part is a single digit:
- 0 – typical indicator according to the SAE standard;
- 1/2 – conveyor failure code;
- 3 – reserve.
The next element is the breakdown group indicator:
- 1/2 – defect in the fuel/air line;
- 3 – ignition and related elements;
- 4 – catalyst;
- 5 – XO of the power plant;
- 6 – ECM and related wiring;
- 7/8 – transmission blocks.
The final two numbers point directly to the problem itself.
Error codes for the VDO combination on the instrument panel of the VAZ 2110
To be honest, these fault codes are not particularly useful. If we compare it with the readings of special on-board computers, such as STAT, then there is, of course, tens of times more useful information and various data. But we’ll talk about this sometime in future articles.
Car: VAZ-2112. Asked by: Maxim Perepelkin. The essence of the question: How to decipher error codes on the instrument panel of a VAZ-2112?
Good day, please help me understand my situation, or more precisely, the error codes on the instrument panel. No matter how much I try, nothing comes of it, everything is somehow too complicated for me, I don’t understand the Internet well enough to find it, but then a friend recommended your site, they say you will find everything there and if you need anything, they will personally help you.
So I decided to ask this question, I hope for a complete schedule of each code and what it is responsible for, so that I could look at it, so to speak, and understand what’s what, and not sit like I did and think, what the hell is this and why. Traveling constantly for diagnostics turns out to be very expensive, thanks in advance.
What does error 8 mean and how to fix it
Error 8, reflected on the on-board computer of the VAZ-2114, means low voltage on the on-board network. Reasons that can cause a decrease in voltage in the VAZ-2114:
- the battery is almost completely discharged;
- erasing or “freezing”, lack of adequate operation of the brushes on the generator.
That is, you can remove error 8 and correct problems in the operation of the VAZ-2114 by charging the car battery or replacing the brushes on the generator, and all this can be done without turning to specialists, in your own garage with your own hands.
What does the error consist of?
The first character means:
The second character in the code means:
The third character identifies the system in which the problem is detected:
The last two characters are a number that corresponds to the error number in the OBD system.
When malfunctions occur in the operation of the engine or other systems, the “Check Engine” indicator is always on on the VAZ dashboard. Its presence may be due not only to a malfunction of the power unit, but also to problems with the wiring or poor contact of one of the sensors.

Table with errors
Sensor malfunctions
To check the flow meter, perform the following steps:
Engine malfunctions
Possible causes of the problem:
If replacing the fuel does not help, it is necessary to diagnose the air intake system. You should tighten the fastening clamps, change the air filter element and check the pressure in the rail (the normalized value is no more than 2.8 atm).
It is also necessary to perform diagnostics:
Diagnostics of high-voltage wires is carried out using a tester; it is necessary to check the resistance. If the obtained value is more than 10 kOhm, then the cables must be replaced. You also need to check the integrity of the spark plugs and make sure there is no carbon deposits on their tips.
If the described actions do not help determine the cause, the cylinders are diagnosed. The user needs to check the compression level, which should be approximately the same in each device. If the obtained values differ by more than 0.5 atm, then the power unit needs to be tested in more detail.
Possible causes of the problem:
To fix the problem, you can try to relearn the throttle valve, to do this, perform the following steps:
Possible solutions to the problem:
Electrical faults
When this combination appears, the following problems are possible:
Possible signs of problems:
Detailed diagnostics of the microprocessor module and its flashing if necessary are required.
If you do not have the appropriate equipment and skills, you can follow these steps to resolve:
Self-diagnosis errors
Three-digit combinations
The appearance of this code may be due to the following conditions:
Composite Combinations
Possible faults
The contact-type sensor is quite reliable, and according to the designers’ plans, it should last at least 50,000 km.
This is ideal under average operating conditions. In practice, it often fails before reaching half of its intended lifespan. Like any mechanics, the controller is very demanding regarding various clearances, frequency and speed of movement of the slider. The situation is complicated by the difficulty of diagnosis. The main symptoms of a malfunction of the VAZ-2110 throttle sensor are very similar to damage to many other components of the car. However, symptoms of damage to the TPS may be as follows: deterioration in the dynamic characteristics of the engine; jerking during intense acceleration; engine stopping when changing gears; “dips” when sharply pressing the gas pedal.
As already noted, the weak point of the TPS is the mechanical moving contact. The resistor slider, moving across the resistive layer, damages it. The thin coating simply rubs off, the contact deteriorates, making further operation of the car problematic. In addition, the moving contact itself may break. In this case, the engine almost does not respond to the gas pedal.
In any case, the TPS cannot be repaired, and there is no point in restoring it. The price of the sensor does not exceed 300 rubles. True, first of all, you need to make sure that it is he who is faulty.
Car self-diagnosis
It should be noted right away that diagnostics on your own and at a service station are slightly different things. A specialized service has the necessary equipment that will allow you to fully identify all existing errors in the operation of your vehicle’s on-board computer.
VAZ 2114 car
Self-diagnosis is also a useful thing, but it is unlikely that you will be able to fully detect all errors if you check it yourself. It is also worth noting that the fault codes in both cases will be different, so we will consider both options separately. So, how is the dashboard diagnosed to identify faults without the participation of the on-board computer? This method is not known to all VAZ 2114 owners, but we will tell you about it.
- Sit in the driver's seat and hold down the odometer button.
- After this, turn the ignition key to the first position.
- Then release the odometer button: you will see the arrows begin to move.
- Press the button again and release it, so you will see the firmware version.
- Finally, press and release the button a third time and if there is a fault, you will see an error code on the screen.
