3929 AGR c control the amount of oxygen sensor in the exhaust gas (lambda probe). MIL (malfunction indication lamp) Error. Request MIL with blocking or non-blocking AGR. For the diagnosis of NOx system checks the value of the amount of oxygen sensor (oxygen sensor). Depending on the values and by AGR state is determined by the need to turn on the lamp and reduce power. If you exceed the limit values from the sensor is sent to request the inclusion of MIL.
Control 3930 AGR c oxygen sensor in the exhaust gases (a lambda probe). Error PR (power reduction). Request PR with blocking or non-blocking AGR. Depending on the values and by AGR state is determined by the need to turn on the lamp and reduce power. If the control values from the sensor detected a low coefficient of work AGR and a correspondingly high level of NOx, sent a request for power reduction.
3931 output stage (Lowside) intake air damper. Checking the output stage for an open or short.
3932 output stage (Lowside) pressure control Checking charge air .. output stage for an open or short.
3936 Too high boost pressure. The pressure of the charge air are exceeded, depending on the engine speed and the position of the valve.
3938 No adaptation of the amount of oxygen in the exhaust gas sensor (oxygen sensor). Verification of the correction factor. The adaptation of the sensor is used to improve the accuracy of the amount of oxygen in the exhaust gases. sensor calibration is performed in a mode of compulsory idling and reduces the risk of failure messages during a working system, exhaust gas recirculation.
3942 pressure charge air intercooler after a low pressure. Checking charge air pressure, checking the reliability of the connection contacts.
Pressure sensor 3943 after the charge air intercooler low pressure. Check the supply voltage, the voltage sensor signal and accurate readings.
3944 temperature charge air intercooler after a low pressure. Checking charge air temperature, checking the reliability of the connection contacts.
3945 discharge air temperature sensor after the low-pressure intercooler. Check the supply voltage, the voltage sensor signal and accurate readings.
3946 Cooler injected high pressure air. Faulty thermostat in a cooler or a failure in the pressure reducer cooler.
3947 Cooler discharge of low pressure air. Faulty thermostat in a cooler or a failure in the pressure reducer cooler.
3963 Error LIN (Local Area Network). Checking the presence of a signal.
3964 transmission of messages by the LIN break. Checking the presence of a signal.
3965 Error LIN (Local Area Network). Checking the presence of a signal.
3966 Self-test oil level sensor. Checking the accuracy of readings.
3972 Monitoring of low znacheniyaNOx. The low amount of oxygen sensor in the exhaust gas value (lambda probe).
3973 charge air pressure in the high pressure circuit. The air pressure is too high (FMI1) or too low (FMI2).
3974 pressure charge air in the low pressure circuit. The air pressure is too high (FMI1) or too low (FMI2).
3975 The gap sensor wires. Broken line IP (FMI3), an open line of Nernst (FMI8) or a virtual mass (FMI7).
3976 Monitoring fault status the amount of oxygen in the exhaust gas sensor (oxygen sensor). Checking the concentration of oxygen. Perhaps because of a defective sensor of expiry.
3978 Electrical fault the amount of oxygen in the exhaust gas sensor (oxygen sensor). Electrical fault output stage of the control unit to the sensor.
3979 the amount of oxygen in the exhaust gas sensor (oxygen sensor). Discovered inactive amount of oxygen in the exhaust gas sensor (oxygen sensor).
3980 oil pressure. Deviation of the oil pressure sensor output at zero pressure.
3981 High exhaust backpressure. Improper operation of the car.
3983 regulator AGR. Internal fault AGR regulator. Via the data message is received on the controller fault.
