Hva betyr feilkoden?
The engine control module monitors the intake camshaft position and has found that it does not match the commanded position. The code is a mechanical fault where the commanded position cannot be reached, and camshaft control is switched off. The fault can only be set when the engine is running and camshaft control is active.
