The VAZ company develops on-board computers so that fault codes for Lada 2115 and other models can be read in two ways at once. The self-diagnosis procedure involves collecting and decoding errors through the on-board display. This method is suitable for quick repairs and troubleshooting.
From 2005 to 2022, more accurate diagnostics became possible. A specially designed OBD2 port allows you to connect equipment to the car. An external computer shows problems down to every detail.
Decoding fault codes VAZ 2115 8 valves
Depending on the type of device, certain symbols and numbers are displayed on the dashboard, indicating the presence of an error. In self-diagnosis mode, the data is reflected on the instrument panel in the square of the on-board display. A one or two-digit number indicating the problem is indicated here.
If diagnostics are performed by a third-party device, error codes are displayed on the computer display and are represented by an alphanumeric code consisting of 5 characters, where the first indicates the area of failure. The second sign indicates the factory code, the third specifies the problem circuit. The last 2 digits indicate the problem itself.
The complete table of faults for the VAZ 2115 contains more than a thousand names and encodings. The following are only the most common problems.
Error 01
The microprocessor has failed. There is a firmware glitch. Repair consists of replacing or reconfiguring the module.

Symptoms of P0132?
It is worth noting that the second/rear oxygen sensor has nothing to do with fuel regulation and is only used to check the operation of the catalyst.
Problems with the fuel mixture, such as those caused by fuel pressure or cylinder misfires, can interfere with the oxygen sensor readings. It is even possible that errors may occur in the catalyst and the second O2 sensor, but this will not lead to errors associated with the measurement circuits.
In most cases, since the catalytic converter is not critical to engine performance and is simply an emissions control device, you won't notice anything other than a Check Engine Light (MIL).
On which cars is this problem most common?
The problem with code P0351 can occur on different machines, but there are always statistics on which brands this error is more common. Here is a list of some of them:

Causes of P0132
Depending on the year, make, and model, the P0132 code can have several causes. Here are some of the most common ones.
- Oxygen sensor malfunction. The most common cause is a malfunction of the sensor itself. Constantly exposed to exhaust fumes and temperature, the O2 sensor has a typical service life of less than 5 years.
- Electrical circuit malfunction. As wires are exposed to the environment, harnesses, connectors, and the sensor itself can be physically damaged by external influences. Water and corrosion are also common causes.
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.
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:
In some cases, errors may overlap each other if the breakdown 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:
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:
The second part is a single digit:
The next element is the breakdown group indicator:
The final two numbers point directly to the problem itself.
