Hva betyr feilkoden?
The engine control module (ECM) adjusts the ignition when combustion knock occurs, so that the knock does not continue. The code is set when knock events from cylinder 1 exceed what the module allows. The knock sensor is mounted on the engine block.
Mulige årsaker
- Engine running on a lean fuel/air mixture
- Poor fuel quality, for example summer fuel in winter
- Engine running too hot
- Intake air temperature too high
- Knock sensor fitted loosely
- Damaged knock sensor
Hva du kan gjøre
- 1Read and clear the code, then road test with the engine warm and under load
- 2Check that the petrol is the grade suited to the season, since the wrong fuel can cause knock
- 3Check that the connector to the knock sensor is secure and clean
- 4If you have a diagnostic tool: see whether the ignition timing is pulled back when the engine knocks during driving
- 5If the fault remains after these checks, have a workshop decide whether the knock sensor should be replaced
