Co oznacza ten kod błędu?

Knock sensor 2, which registers knock on cylinders 1 to 4, must give a signal within limits that depend on engine speed. If the signal is above or below those limits, the fault code is set. The code indicates a general fault without a more specific type.

Możliwe przyczyny

Loosely fitted knock sensor
Damaged knock sensor
Contact resistance or oxidation at the knock sensor plug

Co możesz zrobić

1Read the fault code, clear it and test drive the car
2Check that knock sensor 2 is firmly seated and correctly fitted
3Check the plug on knock sensor 2 for contact resistance and oxidation
4If you have a diagnostic tool: read the knock signal from sensor 2 in live data and see whether it follows engine speed
5Have a workshop with diagnostic equipment replace knock sensor 2 if it is damaged

Objawy, które możesz zauważyć3

Reduced performance
The engine lacks power
The engine hesitates, surges or runs roughly during acceleration, slowing down and constant speed
