Hva betyr feilkoden?
The engine control module checks that the intake camshaft is in the correct position relative to the crankshaft, and adjusts the adaptation when it is not. The code concerns bank 2, sensor A, which is the intake camshaft, and is set when the adaptation changes too much. It is tested when the engine is started or warm.
Mulige årsaker
- Incorrectly set camshafts
- Damaged VVT unit
Hva du kan gjøre
- 1Read the code, clear it and road test the car to see whether it returns
- 2If you have a diagnostic tool: read the intake camshaft adaptation and timing angle for bank 2 in live data with the engine running
- 3Check the engine oil level and that the oil is clean and of the right quality
- 4Have a workshop remove the control valve for cleaning and check the oil passages in the cylinder head
- 5If cleaning does not solve the fault: have a workshop fit a new control valve
- 6If the fault returns: have a workshop check the VVT unit

Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
