Co oznacza ten kod błędu?

The engine control module (ECM) monitors the function of the EGR valve. The fault is set when the signal from the EGR valve position sensor (potentiometer) is faulty. It can be caused by poor contact, a break or a short in the wiring, or a damaged EGR valve.

Możliwe przyczyny

Play, contact resistance or oxidation in the connections to the EGR valve
Open circuit or short in the supply to the EGR valve position sensor
Open circuit or short in the signal wire
Open circuit or short in the ground wire
Damaged EGR valve

Co możesz zrobić

1Read the fault code, clear it and test drive to see whether it returns
2Check the EGR valve connectors for play, contact resistance and oxidation
3Check that the EGR valve is not stuck by dirt and soot; this alone can set the fault
4Check the wiring to the EGR valve for breaks, chafing and shorts to ground or voltage
5If you have a diagnostic tool: read the EGR valve position in live data with the engine running and check that it changes when the valve is activated
6If the wiring is fine: have a workshop check the EGR valve
