What does this fault code mean?
The fault concerns how the knock control works in the engine control module. The control module sets the fault code when it finds a malfunction inside the knock control circuit, so the fault lies in the control module and not in a sensor. The ignition timing may be pulled back as protection.
Possible causes
- Damaged engine control module (ECM)
What you can do
- 1Read the fault code, clear it and drive the car to see whether it returns
- 2Check the fuses and the voltage supplied to the engine control module
- 3Have a workshop with diagnostic equipment check the engine control module and, if needed, replace and program it
Symptoms you may notice2
- Reduced performance
- The emissions warning light is on
What the fault can affect1
- Ignition timing is retarded as a safety measure
General guidance for car owners. Diagnosis on the car can point to a different cause.
