Was bedeutet der Fehlercode?

The fault is mechanical and concerns the setting of the intake air control valve. The engine control module (ECM) checks the learned limits of the 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 cause may be a valve that sticks because of dirt, or a damaged 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, clear it and check whether it returns after a drive
2Check that the control valve is not dirty and does not stick when moved by hand
3Check that the fuses are intact; their locations are shown in the owner's manual or on the fuse box cover
4If you have a diagnostic tool: read the valve's learned limits in live data and see whether the limit for the open position is unreasonable
5Have a workshop with diagnostic equipment redo the setting and check the valve; replace it if it is damaged
