Was bedeutet der Fehlercode?
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.
Mögliche Ursachen
- Damaged engine control module (ECM)
Was Sie tun können
- 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
Symptome, die Sie bemerken können2
- Reduced performance
- The emissions warning light lights up
Was der Fehler beeinflussen kann1
- Ignition timing is retarded as a safety measure
