Was bedeutet der Fehlercode?
An offset fault code means the EGR valve signal is shifted away from the value the engine control module expects. The fault can be in the valve or its wiring, and it makes EGR control go wrong.
Mögliche Ursachen
- Poor contact or oxidation at the EGR valve connections
- Wiring to the EGR valve shorted to supply voltage
- Wiring to the EGR valve shorted to ground
- Break in the EGR valve wiring
- EGR valve stuck or sticking
- Damaged EGR valve
Was Sie tun können
- 1Read off the fault code and erase it, then test-drive and see whether it returns
- 2Look at the EGR valve connections for loose contacts and oxidation
- 3Check that the EGR valve is not blocked by dirt or soot
- 4With a multimeter you can check that the wiring to the EGR valve has no break
- 5Have a workshop check whether the engine control module software needs updating, since that is done with diagnostic equipment
