Hva betyr feilkoden?
The engine control module compares the camshaft position with the crankshaft position and adjusts the adaptation when they do not agree. It is a general fault with no more specific description, and it concerns bank 2, sensor B, which is the exhaust camshaft. It is set when the adaptation rises or falls beyond a certain value.
Mulige årsaker
