Hva betyr feilkoden?
The engine control module (ECM) filters the signal from the knock sensor. If the control module has an internal fault in the knock control filter, the fault code is stored. The fault therefore lies in the control module, not in the wiring or the sensor, and it affects performance and ignition timing.
Mulige årsaker
- Damaged engine control module (ECM)
Hva du kan gjøre
- 1Read the fault code and clear it; drive the car and see whether the fault returns
- 2Check the fuses and the battery voltage, since a poor supply can give faulty signals
- 3Have a workshop with diagnostic equipment check the engine control module and replace it if needed
Symptomer du kan merke2
- Reduced performance
- The emissions warning light lights up
Hva feilen kan påvirke1
- Ignition timing is retarded as a safety measure
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
