Co oznacza ten kod błędu?

Knock in cylinder 2 has grown more frequent than the engine control module (ECM) allows, and it then adjusts the ignition so the knock eases. The knock sensor on the engine block is what registers the combustion knock. The cause may be fuel quality, a lean mixture or an overheating engine.

Możliwe przyczyny

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

Co możesz zrobić

1Read and clear the code, then road test and listen for knocking from the engine
2Fill up with petrol suited to the season, since the wrong fuel quality can cause knock
3Check that the connector to the knock sensor is secure
4If you have a diagnostic tool: look at the ignition timing adjustment in live data and see whether it is pulled back when the engine knocks
5If the fault remains, have a workshop judge whether the knock sensor needs replacing
