Car error codes. Diagnostic Code Fault Codes ATS Codes

OBD (from the English. "On Board Diagnostic") translates into Russian as "on-board diagnostics". In essence, OBD-2 is the technology of detecting a car malfunction or its separate unit using a diagnostic device. This device connects the on-board computer of the car with a laptop, a personal computer or other similar device in order to identify existing faults.

OBD-2 appeared at the end of the XX century in the United States of America. The US government has discovered that the automotive supported by them adversely affects the environment and humanity. In order to mitigate this influence, the law was adopted, which obligated to establish a system controlling the engine operation in electronic control units, directly or indirectly affecting the exhaust gas.

The same law provides for the presence of a protocol to read information on inconsistencies in environmental parameters in the engine and other information on the car diagnostics.

So what is OBD-2 now? OBD-2 is a system that reads and accumulates the necessary information about the work of all automotive systems. The initial ecological specificity of OBD-2 limited its application to diagnose all vehicles faults. Over time, the possibilities of this system have expanded, and it has gained large-scale distribution not only in the United States, but also in cars produced in other countries of the world. In the US, diagnostic equipment that works under the OBD-2 protocol has become mandatory since 1996. This rule concerns not only cars that were produced in this country, but also imported cars implemented in America. After some time, the use of OBD-2 has acquired the status of an international standard, and this system has become popular in all countries of the world.

OBD-2 received such wide popularity due to the fact that it facilitated the work of car services for diagnosing and troubleshooting cars. Of course, because OBD-2 makes it possible to monitor all auto management systems and even with some systems that do not belong to management, for example, body, chassis, etc. Also, OBD-2 allows you to read existing problems and monitor the statistics of the car (Average vehicle speed, the number of revolutions per minute, etc.).

Before the appearance of the OBD-2, the data exchange protocol, the diagnostic connector and its location of each producer of cars vary greatly. As a result, the car repairing master had to first look for the location of the connector, and then pick up the appropriate equipment. Have in stock all kinds of diagnostic devices do not afford even a large car service.

After the appearance of OBD-2, the type of diagnostic connectivity in each car began to do the same and positioning in a certain and easily accessible place, most often in the ignition key or in the car's glove compartment. Video: ELM327 OBD 2

"Pickup"

Despite the fact that the OBD-2 system is standardized, car manufacturers still have some freedom to develop protocols, so the "pinout" of some brands of the car may differ. In the work of OBD-2, several standards are used immediately: ISO9141-2 (all European cars, most Japanese and Chrysler), J1850 VPW (American GM models), J1850 PWM (Ford), J2234 (CAN). Each of the listed standards works with a group of cars, the composition of which is strictly defined. Car service workers are obliged to know the composition of each such group. At the site of the diagnostic connectivity there are contacts for each of the standards. In professional autoskasers, there are many connections and adapters that are suitable for each specific car.

In essence, the "pinout" OBD-2 is standardized requirements and rules that are obliged to comply with car manufacturers in order for the vehicle management system to comply with the requirements of the norms and laws that concern the uninterrupted operation of the car and the number of exhaust gases from it.

The "pinout" of sixteen contact connections OBD-2 provide the following components:

Error codes

The error code consists of five characters, each of which has its own value:

First sign:

1. P is the operation of the engine and automatic transmission;
2. B - the functioning of "body systems" (power windows, central locking, airbags);
3. C is the functioning of the chassis;
4. U is a system of interaction between electronic blocks (for example, to the CAN bus).

Second sign:

1. 0 - common code for OBD-2;
2. 1 and 2 - manufacturer code;
3. 3 - reserve.

The third mark denoting the type of breakage:

1. air supplies or fuel system;
2. ignition system;
3. auxiliary control;
4. idling;
5. ECU or his chains;
6. transmission;
7. transmission.

The fourth and fifth sign is the error number in order.

Also in the description of errors sometimes there are words bank1, bank2. This is the designation of the exhaust pipe. If the car has a regular engine, then bank1 is used, and if there are two exhaust pipes by car, then one is denoted by Bank1, and the second bank2.

Programs

In order to diagnose a car malfunction, have an OBD-2 device and a computer or laptop is not enough. It is necessary to establish a special program that will be the link to diagnose your car's problems. Many OBD-2 devices manufacturers supply such programs complete with the device, but they are most often very uncomfortable in operation, too complicated and have no Russian-speaking menu. Therefore, most users are trying to find a more convenient option of such a program in the Internet. Indeed, the World Wide Web gives you the opportunity to download this kind of utilities for every taste for any platform starting from Windows and ending Android and MacOS.

Programs for OBD-2 on iOS

iPhoneApplication is the leader among the programs for the iPhone and iPad.

Every year the amount of electronics in cars is becoming more and more. On the one hand and safer. But, unfortunately, due to the huge number of electronic technologies, in the event of a fault of a modern car without special electronic equipment, it is not necessary. After all, only thanks to special scanners, we can find out the error code with which you can find out the true cause of the fault. For example, using error codes, we will be able to find out the reason for the appearance of the icon on the dashboard " Check engine"We offer you the main diagnostic codes of the car malfunction, which will give you an idea of \u200b\u200bhow to interpret the most common error codes associated with the appearance of the" engine check "on the dashboard.

Usually if the dashboard appears " Check engine"(More information about this you can read in our article) Many car owners go to the technical autocentre, in order to learn from specialists and computer diagnostics to find out the cause of the electronic error. But also quite a few drivers who, after the" engine check "on dashboard try to set the cause of the error yourself using the scanner connected to the diagnostic port OBD 2 / OBD II The car, which, fortunately, is not very expensive in our time.

Recall that everyone has a special electronic engine control unit (ECM), which not only controls electronic injection, but also performs a number of other important work for normal and efficient operation of the power unit. Also, the electronic computer (ECM) stores all error codes in its memory arising in the order of the engine. Thanks to these codes, we can learn the reason for the malfunction in our car. The fact is that diagnostic malfunction codes in the automotive industry. That is, in essence, the global standard is adopted. That is why the error code of one car brand, as a rule, means the same as the error code of another car brand.

And so we have collected for you the most frequently encountered fault codes of modern cars, with which you can find out, because of what the icon was displayed on the dashboard. That is, you can set the cause of the fault, and naturally it will help you not to guess on the coffee grounds, changing the "tyk" method new parts, sensors and components, and immediately install which component has failed. It will save you not only time during car diagnostics, but also save your money and even nerves.

P0100 - Air Flow Error Error

The air consumption sensor is located in the intake air duct located between the air filter and the intake manifold of the engine. The mass flow sensor measures the amount of the air flow is measured. The mass flow sensor converts air flow measurements into the voltage of the electric current and transmits them into the engine control unit. There are also sensors that transmit information to the engine control unit not using electricity, but using certain frequencies.

Changing the voltage or frequency is always proportional to the number of incoming air. Air flow sensor signal, as we have already said, is controlled by a computer of a car (ECM).

The engine control unit (ECM) uses the data received from the air flow sensor (DMRV) to know the load on the engine and calculate the required amount of fuel injected into the engine.

If the Signal from the DMRV entering the car's computer will be outside the expected value (range), the engine control unit detects a malfunction and gives the P0100 error code, recording it to its constant memory.

For example, the signal from the air flow sensor was higher than expected when the engine does not work or lower than expected when the engine running.

Please note that the P0100 error code can have some problems: no power during acceleration, engine vibration, jump when operating the power unit, etc.

In some cars, the P0100 code in the system may result in the inclusion of an emergency mode of operation of the engine, in which the speed of rotation of the motor will be limited to 2500-3000 rpm.

If, in addition to the P0100 code, there are other errors in the system, then they must also be interpreted primarily.

Cause of the error P0100:

Faulty or contaminated air flow sensor

Open or short circuit in a mass flow sensor in an electrical circuit

Cramp or short circuit in the sensor or ground chain

Other electrical problems with MAF / DMRV sensor wiring, (rust wires, curved terminals, poor grounding, fuse burned, etc.)

Vacuum leakage

Limited air flow after or in front of the air filter

Air flow sensor is incorrectly installed

Problem with Engine Control Unit (ECM)

Examples: In some Nissan cars (for example, Nissan Maxima, Frontier, Sentra, Pathfinder, as well as Infiniti Q30, QX4), the error code of the P0100 appears, as a rule, due to the failure of the mass flow sensor or due to a broken soldering on the sensor contacts .

Including in these cars, DMRV may be damaged by mud / dust, which will also cause an error P0100.

As a solution to the problem with the sensor pollution, Nissan recommends that the air filter body is more common, which also needs to be changed more often, to install only the original Nissan air filter.

What should be verified when the P0100 error appears:

• 1. The engine must be checked for vacuum leaks.
• 2. The connector and wiring between the mass flow sensor and the engine control unit (ECM) must be checked for a break or damage.
• 3. The air duct between the air flow sensor and the engine air intake must be checked for cracks, breaks, the presence of disconnected clamps or on an incorrect connection.
• 4. You need to check the connector and wiring of the DMRV sensor on the reliability of the terminal connection, for corrosion and damage.
• five. . If it is contaminated, it must be replaced.
• 6. Check the voltage and grounding of the sensor on the connector.
• 7. The mass of the sensor must be checked using a voltmeter or using a scanner on different engine speeds. Then you need to compare the data obtained with the reference data, which were previously obtained from a fully suitable sensor.

In most cases, when the P0100 error occurs and in the absence of other problems, it is necessary to simply replace the sensor to the new one. After replacing the sensor in some cars, you need to reset the adapted values \u200b\u200bof the sensor readings in the engine control unit.

The air consumption sensor may cost 1500 to 30,000 rubles depending on the brand and model of the car.

Replacing the air flow sensor does not constitute any complexity. The simplicity of replacement naturally affects the cost of replacing the sensor in the technical center. So the replacement of the sensor in the car service will be not expensive.

Remember that in case of replacement of DMRV, the original sensor is preferable to acquire the original sensor, since the installation of a non-original sensor can cause problems with the engine operation.

Replacing the sensor to a new one, in most cars, the P0100 error will automatically disappear from the system after a short time.

P0106 \u200b\u200b- Absolute Pressure Sensor / Barometric Pressure Sensor Error

Depending on the brand and car model, each modern vehicle is equipped with an absolute pressure sensor (MAP) or a barometric pressure sensor (BARO).

The absolute pressure sensor (MAP) measures the absolute pressure inside the engine intake manifold, which is directly related to the engine load. In the event of a malfunction of the sensor (MAP), the power and thrust of the engine is most often disappeared. There may also be problems when operating the engine at idle. For example, idling speed can be too high than installed by the manufacturer or too low.

The barometric pressure sensor (BARO) measures the atmospheric pressure that is constantly changing depending on the velocity of the vehicle and the engine load.

The computer of the car uses data coming from sensors (MAP) and (BARO) to adjust the amount of fuel injected in.

In some cars, the computer can also use an absolute pressure sensor (IDA) to test the operation of the exhaust gas recirculation system.

Cause of Error P0106:

Voro as a result of damage to the vacuum line, which is suitable for the sensor

Electrical wiring problems. Problems with a mind or power unit of the engine control unit (ECM computer)

MAP / BARO Sensor Fault

Dirty throttle housing

Problems with the recycling system of exhaust gases

Bad air consumption sensor (MAF)

Mechanical problems with the engine

P0130 - oxygen sensor error

The P0130 fault code appears in the engine control system when the oxygen sensor voltage exits outside the set range. This error code can be caused by a breakdown or short circuit of the oxygen sensor chain, the sensor wear, as well as due to too poor or rich mixture of oxygen and fuel, fuel leakage, depressurize the exhaust system, etc.

The vibration of the detonation sensor is converted to an electric current, which enters the engine control unit. The P0325 error code appears when the computer detects that the detonation sensor voltage does not match the equivalent value set.

Typically, problems are associated with the malfunction of the sensor itself or the wiring problems transmitting information from the sensor to the computer.

P0340 - camshaft position sensor error

The camshaft position sensor (CMP) sends information about the position of the camshaft to the computer. This is necessary to control the ignition, for fuel injection and to control the changing phases of gas distribution.

The diagnostic malfunction code P0340 appears in the computer when it cannot detect a signal coming from the camshaft position sensor.

This code usually appears when the camshaft sensor fails, when the wires are configured, which transmit information to the computer, when problems with connectors. Also, a similar error may appear when mechanical problems occur with the engine, with problems with the engine control unit, etc.

P0341 - Non-compliance with the camshaft position sensor data with the crankshaft sensor

The rotation of the engine camshaft is synchronized with the rotation of the crankshaft. The motor control unit constantly receives a signal from the crankshaft position sensor, which compares the information from the camshaft sensor.

Error code P0341 means that the camshaft sensor signal is outside the expected range or its rotation does not correspond to the rotation of the crankshaft.

Cause of error P0341:

Camshaft Position Sensor Fault

The camshaft sensor is incorrectly installed.

Damage to the speed sensor

The presence of foreign materials between the camshaft position sensor and speed sensor

Crash, poor camshaft sensor connector

Timing belt or chain moved to one tooth (or link)

Stretched timing belt or chain

Problems with synchronization mechanism

Electrical interference from the secondary components of the ignition system (high resistance in high-voltage wires, malfunction of the spark plugs, etc.)

P0401 - Insufficiency of exhaust gas recirculation (EGR)

The main task of the exhaust gas recycling system is a decrease in the amount of nitrogen oxides (NOX) in the car exhaust gases. Nitrogen oxides are formed at very high temperatures. The exhaust gas recirculation system sends a small part of the exhaust gases back into the intake manifold, where it dilutes oxygen and the fuel mixture, thus reducing the combustion temperature of the fuel.

The flow of exhaust gases, which are sent back to the intake manifold, is controlled using the exhaust gas recycling valve. In the event of a valve fault, the P0401 error appears in the system.

P0402 - Recycling exhaust recycling

The P0402 error number appears in the car's computer when it is found that an excessive flow of exhaust gases is observed in the exhaust gas recirculation system. With a serviceable exhaust recycling system, it sends back from the exhaust manifold in the intake manifold only a small percentage of exhaust gases to reduce the combustion temperature of the fuel.

Also, this system reduces the content of nitrogen oxides in exhaust gases, which are formed due to the high combustion temperature.

The exhaust gas recirculation system connects the exhaust manifold with an intake manifold with pipes and hoses, and is also equipped with a valve that regulates the movement of waste gases. For example, when the engine is cold, it works at idle or with a large load, the exhaust gas recycling valve must be closed.

The engine control unit is constantly monitored by the exhaust gases and, if necessary, adjusts the position of the recycling system valve. If the value of the exhaust exhaust flows exceeds the established reference values, the P0402 error appears in the system. In this case, in the car there may be problems with the operation of the engine at idle. The turnover on the tachometer can also jump, disappear dynamics, etc.

P0403 - exhaust recycling valve control error

The engine control unit controls the recycling flow of the exhaust gases by opening and closing the exhaust gas recycling valve. Some cars have a vacuum EGR valve. Other cars are equipped with an electric controlled exhaust gas recycling valve (in the photo).

In case of detecting problems in the electrical control chain of the exhaust gas recycling valve, then the P0403 error appears in the system.

The appearance of an error can be associated with the lack of valve power or due to the wear of the valve itself.

P0410 - Recycling System Error

The secondary air supply system submits to the exhaust system an additional portion of oxygen during the start of a cold engine in order to more effectively help the operation of the catalytic neutralizer. In case of detection of problems with the stream of secondary air, an error P0410 appears in the motor control unit.

This error occurs may be associated with the fault of the air supply pump or due to damage to the hoses and valves of the system.

P0420 - Exhaust system catalyst error (insufficient efficiency)

The catalytic converter is installed in the exhaust system and is an important part of controlling vehicle emissions. In order to monitor how much the catalyst is well performing the cleaning of the exhaust gases in the exhaust system, there are two oxygen sensors. One, as a rule, is installed before the catalyst. One after.

The computer computer during the engine operation constantly compares the signals from both sensors. If the catalyst does not perform its efficient operation anymore, the computer records the error system P0420 (for oxygen sensor No. 1) and P0430 (for oxygen sensor No. 2).

In fact, the reasons for which the P0420 error appeared may be set. But in most cases, the appearance of this fault code indicates the obvious problem of the catalyst itself. As a rule, in this case it is necessary to replace the catalytic neutralizer.

Unfortunately, the catalyst of any car is an expensive component.

P0505 - idle control error

The P0505 code means that the computer of the car cannot adjust the idling of the engine properly. Usually when this car error appears, it starts working with failures. For example, the engine turnover is started, or the engine stalls at idle. There may also be observed either too small idle speeds, or very large.

The P0505 error may appear for many reasons, ranging from vacuum leakage by the throttle, clogging of air channels and ending with air valve contamination, as well as a dirty throttle body. Also, in the event that this error occurs, there may be problems with the wiring or connectors of the non-idling system.

How does an idle system work in the car?

In modern cars, the engine control unit constantly regulates the number of engine speeds at idle depending on the conditions. This is done by increasing or decreasing air flows that are traversed by the throttle of the engine. You can clearly see how the idling system works while heating a cold engine when the system for quick warm-up of the power unit adds engine speed and then, as the motor warms it gradually reduces its turnover.

In some cars, a control air valve (IAC) or a solenoid (in the photo) is also used, which control the air flow.

In this system, a valve that is controlled by an engine control unit is used to adjust the idle speed of the engine. Depending on the conditions, the computer slightly opens or closes the airflow control valve (IAC).

If the car is not equipped with an IAC valve or a solenoid controlling air flow into the throttle bypass, then, as a rule, the idling is controlled by electronics that opens or closes the throttle depending on the situation and conditions. Thus, the system can automatically, both add and reduce the amount of air flow into the engine.

Scientific progress does not stand still, and electronics occupies almost all spheres of society. Each vehicle consists of many different electronics and devices. This simultaneously complicates the maintenance of the car and simplifies it. With the help of special blocks, the driver can identify a malfunction in the early stages of its development.

Modern vehicles are equipped with self-diagnostic blocks that constantly produce a survey of all important technical modules and machine components. Such sensors will allow you to identify any malfunction in the operation of the engine, transmission or electricians. If you find a malfunction, you get through the electronic control unit code value. But how to understand what it means? To solve this task, a special application for motorists "OBD 2 error codes" has been developed. In this review you will learn how to use this utility.

Short description of the program

The name of the application speaks for itself, it is clear from it that the main task is to enlighten the user about the system failures of the car. OBD 2 error codes are a three-dimensional directory in which all modern car brands are collected. For each brand there is a partition in which all possible code values \u200b\u200bof the vehicle error are listed.

Developers embodied a fairly useful guide for car enthusiasts. A convenient and efficient search system will allow you to find information about your car brand in seconds. But in addition to this useful information, the driver will find something else:

What is the codes of the car error codes, how are they formed and what to do when the indicator signal signables error lights up? These issues often ask car owners, especially those who only recently acquired a car and mastering driving.

All electronic control systems of the modern car have a self-diagnostic function that informs the driver about the faults. In fact, it turns out that the onboard computers track not only the situation on the road, but also almost all the internal processes that occur in the car. Such management and diagnostic systems may differ even in one brand cars. However, the diagnostic principle itself remains unchanged: there is a continuous reading of signals from several dozen sensors, the reconciliation of the results obtained with the specified values \u200b\u200band, most importantly, when an error is detected, saving its code in the computer's memory. In the future, the car error codes can be read using an on-board computer or specialized diagnostic equipment: adapters, scanners, other dealerships.

OBD2 error codes by car brands

The OBD-II abbreviation denotes an onboard self-control standard, which provides comprehensive control of the engine, allows monitoring of various additional systems, controls the auto control network. It was developed in the 90s and in many cases is a mandatory protocol for the implementation of on-board diagnostics. Inside this standard, manufacturers use various communication protocols with onboard electronic equipment, through a special 16-pin trapezoidal connectivity, which is located in the steering wheel area. In this case, each diagnostic equipment is used for a particular brand or groups of cars. To illustrate, you can bring the following examples:

- Honda HDS adapter with software and drivers - Diagnizes ACURA and HONDA cars;

- Professional Bars IV scanner - for Ford diagnostics, and with appropriate adapters - for other car brands, such as Toyota, Hyundai, Mazda, Mitsubihi, Nissan;

- Dealer diagnostic DST-14T scanner recommended by AvtoVAZ - allows you to quickly find and decrypt the VAZ car error code.

The code itself consists of 5 characters: one title Latin letter and a four-digit number.

Letter means:

- P - engine malfunction or automatic gearbox;

- B - windows, central locking, other body systems;

- C - a problem with the running part of the car;

- U - Inter-Block Tire Exchange Information.

First digit code:

- 0 - position provided for ELM327 adapters;

- 1, 2 - positions for the coder of the manufacturer;

- 3 - reserve.

Second digit:

- 1, 2 - blending formation;

- 3 - Ignition system elements;

- 4 - additional systems;

- 5 - control of systems that ensure idle stability;

- 6 - malfunction in the control unit;

- 7, 8, 9 - transmission control;

- 10, 20 - codes installed by the manufacturer depending on the brand of the car.

The third and fourth digits are a specific malfunction number. Error codes for cars supporting this protocol are divided into two categories: common or, as they are also called, basic - uniforms for all cars and extended or additional error codes for car brands, significantly expanding diagnostic capabilities.

Car error codes

In order to quickly determine the location of the car malfunction not enough to have diagnostic equipment and a laptop. You need to install the car error codes. As a rule, it comes complete with diagnostic equipment. Today there are a lot of such programs, so every car owner can choose a utility for any platform, starting with Windows and ending with Android. With their help, you can quickly learn OBD-2 error codes right on the go. For example, using the ELM327 Bluetooth adapter by connecting it to the Diagnostic OBD-II connector and using a special Android application, you can easily get a list of error codes and find out that each of them means.

Having knowledge about the codes of the car errors, knowing how to receive and decipher them, you can always keep the "hand on the pulse" and respond to emerging faults in time.
