Hva betyr feilkoden?
The engine control module checks that the intake camshaft is at the correct position relative to the crankshaft. If the position deviates, the adaptation is adjusted, and the fault code is stored when the adaptation becomes too large. The code applies when the camshaft position is too low in relation to the crankshaft.
