Hva betyr feilkoden?
The engine control module (ECM) adjusts the intake camshaft position with a changeover valve on bank 2, the rear cylinder row close to the passenger compartment. The fault code is set when the control signal to the valve is too low. The causes can be poor contact or a signal or supply wire shorted to ground.
Mulige årsaker
- Contact resistance in the connectors
- Signal wire shorted to ground
- Supply wire to the valve shorted to ground
- Damaged intake camshaft changeover valve
Hva du kan gjøre
- 1Check that the fuse for the valve circuit is intact. If it has blown, use a multimeter to check whether the wire is shorted to ground
- 2Check the valve connector for contact resistance and oxidation, and make sure it is seated firmly
- 3Have a workshop measure the valve resistance
- 4With the connectors disconnected, use a multimeter to check that the signal wire is not shorted to ground
- 5If the fault remains after these checks, have a workshop with diagnostic equipment check the control module
