Was bedeutet der Fehlercode?

The control module monitors the function of the EGR valve. A fault in the valve or its wiring that leads to incorrect EGR control produces this code. It is only set, however, when a related EGR fault has already been recorded and the control module's built-in routine for freeing a stuck valve has failed.

Mögliche Ursachen

Bad contact, resistance or oxidation in the EGR valve connectors
Dirt or soot making the EGR valve stick
Open circuit in the cable to the EGR valve
Cable to the EGR valve shorted to ground or voltage
Damaged EGR valve

Was Sie tun können

1Switch off the ignition and check the EGR valve connectors for looseness, contact resistance and oxidation
2The valve can stick because of soot and dirt. Look for this and have a workshop decide whether it should be cleaned or replaced
3Use a multimeter to check that the wires to the EGR valve motor have no open circuit and are not shorted to ground or voltage
4If the fault remains, have a workshop with diagnostic equipment check the valve and its wiring
