Hva betyr feilkoden?
The engine control module has found a fault in the signal wire to the camshaft reset valve, and the signal is missing. The fault is intermittent, meaning it comes and goes and may not be present right now. The cause may be a temporary open circuit, a short circuit or a connection with varying contact resistance.
Mulige årsaker
- Open circuit in the signal wire
- Contact resistance in the connectors
- Open circuit in the voltage supply wire
- Signal wire shorted to ground
- Defective reset valve
Hva du kan gjøre
- 1Check the connector at the reset valve. A connection that makes contact only now and then may be the cause
- 2Gently move the wiring and connector with the ignition on and see whether the fault follows
- 3Check that the wiring has no open circuit, chafing or damage, especially where the cable moves
- 4Repair loose connectors and damaged wiring. Replace the reset valve if the fault remains
Symptomer du kan merke2
- The malfunction indicator lamp comes on now and then
- Uneven idle when the fault is present
Hva feilen kan påvirke2
- The variable camshaft is switched off
- The camshaft stays in the position for maximum performance
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
