Was bedeutet der Fehlercode?

The ECM reads oil pressure through the combined oil pressure and oil temperature sensor. The fault is stored when the signal from the oil pressure sensor is too high while the engine is running. The module then uses a fixed oil pressure value instead of the measured one.

Mögliche Ursachen

The signal wire is shorted to supply voltage
The combined oil pressure and oil temperature sensor is damaged

Was Sie tun können

1Check that the fuses are intact
2Look for chafed wiring from the sensor that may have touched a live supply part
3Use a multimeter to check that the signal wire from the sensor has no voltage when the ignition is off
4If you have diagnostic equipment: read the oil pressure in live data with the engine running and see whether the value sits at an unrealistically high level
5If the wiring and connector are sound, have a workshop check the combined sensor

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
