Was bedeutet der Fehlercode?
The fault is intermittent, meaning it comes and goes, and it concerns the signal wire to the EGR valve, which controls the return of exhaust gases. The engine control module sets the code when it finds a fault in the wire, such as a short to ground, an open circuit or a short to voltage. The EGR control is then switched off.
Mögliche Ursachen
- Signal wire short-circuited to voltage
- Defective EGR valve
- Signal wire short-circuited to ground
- Open circuit in the signal wire
Was Sie tun können
- 1Inspect the wire to the EGR valve for breaks, chafing and shorts to ground or voltage
- 2Check the EGR valve connector for contact resistance and oxidation
- 3Use a multimeter to check that the signal wire to the EGR valve is not broken and not shorted
- 4Have a diagnostic tool? Activate the EGR valve and check that it moves
- 5If the wire and connector are sound but the fault remains, have a workshop replace the EGR valve
