Volkswagen fault code P157000 engine control module

Hello, according to the import car market.

Learned: Fault code: P1570

Chinese meaning: engine control module (ECM) -immobilizer active

Category: Powertrain systems (manufacturer's own meaning).

Detailed meaning: The engine control module, also known as the engine control unit (some car engine control modules and transmission control modules are integrated together to become powertrain control modules), controls the operation of the entire engine. Its main function is to control the optimal amount of fuel injected into the engine and the timing of ignition.

Another important role is the component responsible for monitoring and controlling exhaust emissions. The role of the anti-theft control module is to ensure that the car is only allowed to start when a special key is present and it matches the various components.

Now the car is electronically controlled engine, there are a lot of sensors to detect the working condition of the engine, and then the signal is fed back to the computer, after the computer analysis and comparison, and then to control the fuel injection ignition and air intake, if the engine sensor detection is problematic, the computer will report the fault code, to remind the owner, the engine needs to be tested and repaired, so we have to find out the cause of this failure, there are often the following reasons, for reference only: 1. The sensor is damaged, the contact is poor or the signal is interrupted; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. a spark plug.

Fault, ignition coil.

Fault; 6. The fuel pump is faulty and the oil circuit is blocked; 7. The air conditioner filter is blocked.

The specific situation is analyzed as follows; 1. Sensor problems; The sensors mentioned here include water temperature and crankshaft.

Position, air flow, intake air temperature, J-round oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain engine data, which will cause the engine fault light to turn on. 2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

Poor combustion of mixed cleaning and changing line gas; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, and these will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally turn on the fault light to warn of the intake air intake problem; When the engine burns, it needs to take in the air, and in the process the air cleaner is required.

If the air filter of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be very clogged in the long run, and in serious cases, it will cause the engine failure light to turn on. pressurization issues; Intake booster lines, turbochargers.

It will also cause the engine failure light to illuminate. The most common of these is turbocharger damage, while the vehicle can also experience symptoms such as oil leakage, high oil consumption, loss of power, metal noise, and blue or black smoke from the exhaust pipe. 7. Exhaust problems; Rear oxygen sensor, three-way catalytic converter.

Exhaust camshafts.

and bearings. The most common of these is a failure of the three-way catalytic converter that causes the engine failure light to illuminate. The use of leaded gasoline, the use of leaded or silicone lubricant additives, the bump of the three-way catalytic converter, and the failure of the engine oil supply system are some of the factors that can easily cause the failure of the three-way catalytic converter.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions!

According to your fault is the electromechanical unit of the gearbox, a problem caused by this failure, if you need to repair, you have to replace the electromechanical unit first, and then do **matching to **matching** matching, and then do a drive matching can solve your problem, and the approximate cost of replacing the electromechanical unit on the market is also about 5000.

There will be differences in different regions**, and you can also consult your local car repair shop for details.

Hope mine can help you!

P137 Fault Code for Audi.

Volkswagen, which means long term fuel trim, additive fuel - system too rich (bank 1).

Background: Fuel trim is when an electronic control unit (ECU) controls fuel delivery by increasing or decreasing the injector's open time, resulting in an optimal air-fuel ratio (air-to-gasoline mass ratio: 1).

Too strong an air-to-air ratio means that the fuel delivery volume is too large, and an air-to-air ratio is too thin to mean that the fuel delivery volume is too small. Causes of failure include failure of the intake flow sensor or manifold absolute pressure (MAP) sensor, fuel pressure too high, fuel pressure regulator failure, fuel injector failure, oxygen sensor.

Fault, camshaft.

Timing errors, overfilling of oil, errors in evaporative discharge systems, failure of electronic control modules (PCM or ECM), etc.

After your car is troubleshooting, it generally needs to be cleared**. When clearing **, it is necessary to follow the fault removal method specified in the designated model, and do not simply remove the battery negative pole with the iron wire to clear the fault**. Otherwise, it can cause trouble in two ways:

First, the control computer of some models loses the "experience memory", I believe we all know, many models of the car computer is with the function of automatic memory, easily remove the battery negative pole of the belt argument iron wire, will automatically clear the storage in the random memory.

RAM) so that the car does not perform well for a long time after maintenance, or after a period of driving, it has been cleared out of the fault**; Second, sometimes it will lead to some useful functions not working, such as audio locking is one of the more common examples, in this case, you need to follow a more cumbersome procedure to decrypt the sound system in order to restore the normal operation of the sound system.

Fault code: P0118.

Chinese meaning: Engine coolant temperature (ECT) sensor 1 circuit is high.

Category: Fuel or air.

The reason why the voltage of the engine coolant temperature sensor circuit is too high: use a digital multimeter to measure the voltage between the engine coolant temperature sensor signal circuit and the reliable grounding to see if it is within a reasonable range of volts

1. If the voltage is lower than volts, test whether the engine coolant temperature sensor signal circuit is too high or open-circuit.

2. If the voltage is higher than volts, test whether the signal circuit of the engine coolant temperature sensor is short-circuited to the voltage.

3. If the test result of the engine coolant temperature sensor signal circuit is normal, and the voltage is still not within a reasonable range, the engine control module has a problem and needs to be replaced.

The meaning of Volkswagen P1592 fault code 0238 is that the turbocharger supercharger booster sensor A circuit is high, that is, the engine air filter is blocked, resulting in insufficient air intake, and the sensor senses that the turbocharging effect reaches the maximum value, or the air intake is insufficient, and the signal voltage of the booster sensor is higher than volt, the fault code will appear, and the replacement of the vehicle air intake filter can be solved, and the specific operation steps are as follows:

1. Locate the engine compartment air filter.

2. Open the filter clip.

3. Lift the filter lid upwards with your hand.

4. Extract the internal filter.

5. Replace the new filter cover and you're good to go.

6. Complete the drawing.
