Was bedeutet der Fehlercode?

The engine control module (ECM) compares the actual position of the intake air control valve with a calculated reference value. If they do not match, the fault code is stored and the valve is considered stuck in the open position. The fault gives general fault information without a specific type.

Mögliche Ursachen

The control valve is stuck in the open position
Damaged control valve in the intake air inlet

Was Sie tun können

1Check that the fuses are intact; their locations are shown in the owner's manual or on the fuse box cover
2Check that the flap in the intake pipe moves freely and is not stuck in the open position
3If you have a diagnostic tool: read the valve's reference value and actual position in live data with the engine running and compare them
4If you have a diagnostic tool: read the fault status and check whether the fault code returns after a test drive
5If the fault remains: have a workshop with diagnostic equipment check the control valve and the EGR function

Symptome, die Sie bemerken können1
