Was bedeutet der Fehlercode?

The engine control module (ECM) compares the learned limits of the control valve for the closed and open positions. If the limit for the open position is outside the permitted range, the fault code is stored. The fault is general and does not specify the type. The cause can be a sticking control valve due to dirt or contamination, or a damaged control valve.

Mögliche Ursachen

Sticking control valve due to dirt or contamination
Damaged control valve in the intake air inlet

Was Sie tun können

1Read the fault code and clear it, then run the engine and see whether it returns
2Check that the control valve in the intake air inlet moves freely and is not dirty or blocked
3Check that the fuses are intact; their locations are shown in the instruction manual or on the fuse box cover
4If you have a diagnostic tool: read the control valve's learned limits in live data with the engine running and see whether either one lies outside the expected range
5Have a workshop with diagnostic equipment check the valve and replace it if it is damaged
