designation of errors on the on-board computer of the VAZ 2115

Designation of icons on the dashboard of the VAZ 2115

The following describes the warning lights and panel indications, which are indicated and numbered in the photo above.

Why does the lambda probe die?

We have already clarified above that the service life of the oxygen sensor is 80-160 thousand km. You probably have a question: why is there such a spread in the resource, as much as 80 thousand km? In fact, it depends on the conditions in which the car was operated:

1. Bad gasoline, the exhaust of which contains a lot of lead and iron, clogs the sensor electrodes after several fill-ups.
2. Poor condition of oil scraper rings and caps. Because of them, oil can get into the mixture, and with it into the exhaust system.
3. Due to clamped valves, pops are released into the exhaust system, which destroy the working surface of the sensor.
4. Due to an incorrect mixture, ignition timing, as a result of which the sensor overheats, crackling from the high temperature of the converter or catalyst.

Tidy 2115: description and purpose of buttons and knobs

If everything is simple with the levers on the steering rack, there is a headlight position switch and a turn signal switch on the left. Buttons are more difficult.

Lada 2115: the oil light on the center panel is on

If an icon in the shape of a watering can appears on the console, this indicates that there are problems in the engine lubrication system. This is caused by a drop in the oil level in the crankcase or a pump malfunction. If the engine is old, the problem may be caused by clogged oil lines.

What does the exclamation mark on the Lada 2115 tidy mean?

On the "tag" the symbol is used in only one form - a red indicator in a circle. The icon indicates a malfunction in the vehicle's brake system. If this symbol lights up while driving, stop and find the cause of the breakdown. Usually it is enough to add fluid to the expansion tank or replace worn pads.

The battery light on the dash is on 2115

A red battery icon indicates that the battery is not charging properly. A complete diagnosis of on-board systems associated with the generator set and its wiring is required.

How to fix the problem?

If the battery is low, it needs to be charged. This is done like this:

After charging, you need to check the battery voltage using the above method. If it is within the normal range, install it on the car. Observe for several days to see if the battery is draining. If rapid discharge occurs for no apparent reason, the device is likely faulty. Therefore, you will have to buy a new battery.

If the generator is faulty, it is usually enough to replace its brushes to restore functionality. To do this you need:

If this does not help or visible defects are found on the device, other parts will also need to be replaced. VAZ 2114 generators are repairable. You can repair them yourself. But in some cases, it is better to replace the electric generator or contact specialists to restore it.

If the low voltage is associated with other faults that you could not identify yourself, you need to visit an auto electrician.

Description of faults

Tidy 2115 stopped working

Occurs after power surges or moisture getting under the panel (condensation). If the device has completely failed, but other elements of the car are working, check the fuse and wiring of the element.

When only part of the panel does not show or the board lighting has failed, perform diagnostics of the illuminators and their contact groups.

Tidy does not light up

If the backlight does not function, as well as the dimensions on the left side of the car, check the corresponding fuse. When the insert is working properly, you will need to diagnose the mounting block for voltage.

Panel 2115 blinks

It happens when the device does not work correctly. The backlight blinks and the elements constantly jump. There are problems with contacts here. The pads may become loose or oxidized.

The solution to the problem is to clean the contacts from oxidation and tighten/replace the pads.

The temperature sensor on the device 2115 does not work

The solution lies in diagnosing the system and correcting breakdowns.

The arrows on the dashboard 2115 do not work

The fault lies with the blown fuse F3. Before replacing it, be sure to diagnose the wiring and eliminate problems and possible short circuits.

Operating principle of DC (lambda probe)

The working surface of the sensor is a ceramic material coated with platinum.

The operating temperature of the surface is 350 degrees Celsius and above. Therefore, before heating the lambda probe, during the first 5 minutes after starting the engine, the working mixture is adjusted according to the readings of other sensors in the engine power system. To speed up the heating of the part to operating temperature, an electric heater is installed in it.

The principle of operation is as follows: exhaust gases cover the working surface of the lambda probe, which in turn reacts to the difference in oxygen levels in the exhaust gases and the environment. It then sends a signal to the ECU, which adjusts the fuel mixture.

How much does a shield cost?

In 2022, you can find a tidy device from 1000 rubles. If you need to purchase a complete module with all the plastic and instruments, the purchase will cost approximately 8-10 thousand.

The standard dashboard of the Lada 2115 is informative and has a discreet design. The module is easy to read and intuitive even for novice drivers.

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).

Error codes VAZ 2115

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.

On which cars is this problem most common?

The problem with code P0132 can occur on different machines, but there are always statistics on which brands this error occurs more often. Here is a list of some of them:

• Audi
• Chery
• Chevrolet (Chevrolet Aveo, Camaro, Cruz, Lanos, Lacetti, Spark, Epica)

With fault code P0132, you can sometimes encounter other errors. The most common ones are: P0130, P0131, P0134, P0135, P0138, P0152, P0172, P0328, P0451, P0496.

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.

Error code 2

The fuel level sensor in the tank is damaged or stuck. Disassemble the system and inspect the sensor for damage.

Fault 3

It is a combination of errors No. 2 and 1. Troubleshooting is indicated above.

Breakdown 4

Excessively high voltage in the network. The reason lies in a short circuit in the line.

Error 8: Lada 2115 8 valves

The problem arises when the car has an injector. The causes and elimination of the malfunction are completely opposite to point number 4. Here we are talking about a critical voltage drop in the on-board network, which is caused by battery failure or damage to the generator set.

Error 10

This means that when the engine is under high load, a lean fuel mixture enters the engine. The behavior causes a malfunction of the injector or throttle valve.

Breakdown 11

Indicates the presence of two or more problems at the same time. The number is obtained by adding the codes 8 and 3.

Fault 12

The check engine light is damaged or there is a problem with its wiring. It can be eliminated by studying the entire highway followed by repairs.

Error 14

The coolant temperature sensor is faulty or not working correctly. The situation can only be corrected by completely replacing the part - the sensor cannot be repaired.

Reasons for error 8

Knowing what error number 8 on the instrument panel means, it is easy to determine the reasons for its occurrence. There are only two main reasons. This is a discharged or faulty battery or a failed generator.

For the latter, this most often indicates the need to replace the brushes, since the old ones are already worn out. In addition, the code may occur in such cases as:

Sometimes an error indicates other problems. But this happens very rarely.

You can determine the exact reason for this behavior of the car on your own. First, you should visually inspect the battery and generator and their contacts. You may notice oxides and other defects on the terminals and connectors. There is often visible damage to the wiring. The battery terminals may not be properly tightened. In rare cases, you may notice that the battery is swollen.

It is useful to check what the voltage is in the on-board network on the dashboard. You need to pay attention at what point it decreases or constantly remains low. You should also diagnose the battery and generator with a multimeter in voltmeter mode.

Battery diagnostics is performed as follows:

If the value is lower, then the battery needs to be charged. If after this, it does not charge completely or discharges quickly, it should be tested with a load fork. This can be done independently or at a car service center.

You should also check the operation of the generator. To do this you need:

How to reset errors on a 2115 injector yourself, without a computer

To reset dashboard codes, drivers use 2 methods.

In the first option, faults can be eliminated by disconnecting the power terminals from the battery. The circuit is opened for 15 minutes and put back together. After this, the bookmaker will restart and information about problems will be updated.

You can also perform a reset using third-party equipment, but this is relevant for service stations and service stations.

It’s easy to count Lada 2115 errors yourself. The disadvantage of the procedure is the impossibility of accurately determining the exact location of the breakdown. For detailed diagnostics, it is recommended to use special equipment.

What does P0132 mean?

An internal combustion engine ignites hydrocarbon fuel (HC) mixed with oxygen (O2), using the resulting energy to rotate the engine.

The exhaust gas stream ideally consists of water (H2O), carbon dioxide (CO2) and unreacted nitrogen (N2). Unfortunately, due to inconsistencies in engine operation, air and fuel temperatures, fuel composition, and a number of other factors, exhaust gas chemistry may be less than ideal.

For example, excessive cylinder temperatures can lead to the formation of nitrogen oxides (NO and NO2). An excessively high air-fuel ratio (FA) can result in high unburned hydrocarbon levels. Other conditions may produce carbon monoxide (CO), ozone (O3), and particulate matter less than 10 microns or 2.5 microns in size (PM2.5 and PM10).

To reduce these combustion emissions, the engine control module (ECM, PCM) monitors air and fuel temperatures, intake air mass and flow, engine speed and load, and more to fine-tune fuel ratio, valve timing, ignition timing, and more.

However, even these controls are not enough to prevent some harmful emissions from being generated. So the last step is a three way catalytic converter. A chemical filter that converts harmful emissions into safer compounds.

Unburned HC and PM2.5 and PM10 emissions combine with CO, O3, O2 to produce H2O and CO2. The controller compares the oxygen sensor readings before and after the catalyst to monitor its operation.

The front oxygen sensor in front of the catalyst is used primarily as feedback to fine-tune the fuel quantity, but is also used by the ECU to check the converter.

During normal operation, the controller increases and decreases the amount of fuel, always trying to achieve a fuel ratio of 14.7:1, using the oxygen sensors to check.

Normal oxygen sensor readings usually fluctuate several times per second - high/low signal. If the catalytic converter is working properly, the heated oxygen sensors (HO2S) will fluctuate very little.

Every few seconds the controller will supply fuel higher or lower than normal, to which the oxygen sensors will react by indicating a higher or lower voltage than normal.

If the catalytic converter is working properly, the readings of the downstream/second oxygen sensor will remain virtually unchanged. If the voltage of the second O2 sensor changes at the same time as the voltage of the front one, the ECU determines that the catalyst is not working properly and activates an error related to the function of the catalyst.

However, before the ECU can control the catalyst, it must receive confirmation that the front and rear oxygen sensors are working correctly. To do this, the controller checks the heater and signal circuits for the correct voltage and resistance. If the control unit detects that the signal voltage is higher or lower than acceptable, it illuminates the Check Engine Light and stores a trouble code.

Bank 1 and Bank 2 tell you which cylinder block it is, left or right if it is a V-twin engine. Bank 1 always contains cylinder #1.

Sensor 1 or Sensor 2 refers to the position of the sensor before or after the catalyst. Sensor 1 is located in front and sensor 2 is located after the converter.

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.

Where is the oxygen sensor (lambda probe) located?

For 1.5 l engine

The lambda probe (number 11) is installed in the exhaust system on the exhaust pipe. Screwed in from above, in front of the resonator or spacer (if there is no resonator). In other words: put the car in a pit and look throughout the exhaust system for a sensor sticking up. DC is the only sensor that is installed in the exhaust system, so you won’t miss it.

Exhaust system for 1.5l engine

For 1.6L engine

The exhaust system of this engine is slightly different from the 1.5 liter. Pay attention to the figure: In this exhaust system, 2 DCs are planned (at number 2) - both are located on the catalytic collector. These engines are equipped with both 1 and 2 oxygen concentration sensors: Euro-2 toxicity standard - 1 DC, Euro-3 - 2 DC.

How does a mechanic diagnose a P0351 code?

When diagnosing this error code, a mechanic will do the following:

• Reads all stored data and error codes using OBD-II scanner
• Clear error codes from the computer's memory and test drive the vehicle to see if P0351 appears again
• If the error code appears again, check the ignition coils as well as the associated wires for wear and damage.
• Find out whether the fault concerns only one of the cylinders or all cylinders of the engine using a scanner
• If the fault concerns only one engine cylinder, check the corresponding spark plug and its wire for wear and damage.
• If a malfunction is detected in all engine cylinders, check the primary winding of the ignition coil
• If no problem is found, check the ECM
