Was bedeutet der Fehlercode?

The engine control module (ECM) has registered a faulty reading from the oil level sensor, and the code is stored. The sensor reports oil level, oil temperature and oil quality, which the module uses to calculate the oil level. The fault most likely lies in the sensor itself.

Mögliche Ursachen

Damaged oil level sensor

Was Sie tun können

1If you have a diagnostic tool, read the oil level, oil temperature and oil quality values in live data with the engine running and see whether they look reasonable
2If one value is wrong while the others are reasonable, that points to the oil level sensor
3Check that the connector at the oil level sensor is fully seated and clean
4Clear the code and road test with the engine running to see whether it returns
5If the fault remains, have a workshop try a new oil level sensor
