Hva betyr feilkoden?
The signal from the rear knock sensor is too low. The control module checks the signal against limits that depend on engine speed, and the code is set when the signal falls outside them.
Mulige årsaker
- Contact resistance in the connector
- Defective knock sensor
Hva du kan gjøre
- 1Clear the code and road test the car to see whether it returns
- 2Check the rear knock sensor connector: fully seated, clean and free from oxidation
- 3Use a multimeter to check that the wire to the rear knock sensor is intact
- 4If you have a diagnostic tool: see whether the knock signal in live data changes as engine speed rises
- 5If the connector is clean but the fault remains, have a workshop fit a new knock sensor
Symptomer du kan merke1
- The engine performs worse
Hva feilen kan påvirke2
- Knock control is disabled
- Ignition timing is retarded for safety reasons
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
