Was bedeutet der Fehlercode?

The engine control module (ECM) controls the EGR valve, which feeds part of the exhaust back into the engine to lower emissions. The ECM has received a signal from the valve or its wiring that does not match the expected EGR control, so the EGR function is faulty.

Mögliche Ursachen

Poor contact, contact resistance or oxidation at the EGR valve connector
Wiring to the EGR valve shorted to supply voltage
Wiring to the EGR valve shorted to ground
Break in the wiring to the EGR valve
EGR valve overheated
Damaged EGR valve

Was Sie tun können

1Read off the fault code, erase it and test-drive the car to see whether it returns
2Inspect the EGR valve connector for loose contacts, contact resistance and oxidation
3Look for breaks and chafing in the wiring to the EGR valve
4If you have a diagnostic tool: check in live data that the EGR valve position changes when the engine speed rises
5Have a workshop with diagnostic equipment check the valve and measure the signals if the fault returns
