Was bedeutet der Fehlercode?

The ECM reads oil pressure through the combined oil pressure and oil temperature sensor. The fault is stored when the module detects an internal fault in the sensor, which means the fault lies in the sensor itself. The module then uses a fixed oil pressure value instead of the measured one.

Mögliche Ursachen

The combined oil pressure and oil temperature sensor is damaged

Was Sie tun können

1Check that the fuses are intact
2Check that the connector to the sensor is firmly seated and not corroded
3If you have diagnostic equipment: read the oil pressure in live data with the engine idling and when the revs are raised, and check whether the value changes
4Clear the code and road test the car. If the code comes back, the sensor is probably damaged
5Have a workshop check the combined oil pressure and temperature sensor and replace it if it is damaged

Symptome, die Sie bemerken können1

No noticeable symptoms for the driver

Was der Fehler beeinflussen kann1

The control module uses a fixed oil pressure instead of the measured value
