Was bedeutet der Fehlercode?

The engine control module (ECM) monitors the EGR valve. A fault in the valve or its wiring that causes incorrect EGR control sets the code, but it is only set when a related EGR code is already stored and the control module's built-in routine for freeing a jammed valve has failed. Dirt and soot can make the valve stick.

Mögliche Ursachen

Poor contact, contact resistance or oxidation at the EGR valve connector
The EGR valve sticks because of dirt or soot
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 connector for looseness, contact resistance and oxidation
2Look for soot and dirt at the valve, and have a workshop decide whether it needs cleaning or replacing
3Use a multimeter to check that the signal wire to the EGR valve has no open circuit and is not shorted to ground or voltage
4Also check that the earth wire has contact and that the supply wire is not shorted to ground
5If the fault remains, have a workshop with diagnostic equipment check the wiring to the EGR motor and the valve, as this needs measurement

Symptome, die Sie bemerken können2

Yellow warning symbol and text message in the display
The check engine lamp lights or behaves abnormally

Was der Fehler beeinflussen kann1
