Was bedeutet der Fehlercode?
The fault concerns the position sensor circuit for the bypass valve, where the signal is too high. It is set by a fault on the PWM signal linking the ECM and the valve, or by excessive temperature in the valve's end stage.
Mögliche Ursachen
- Loose contact, contact resistance or oxidation in the connections
- Signal wire shorted to voltage
- Open circuit in the supply voltage
- Open circuit in the signal wire
- Damaged bypass valve
Was Sie tun können
- 1Read the code, clear it and road test to see whether it returns
- 2If you have a diagnostic tool: read the bypass valve position value in live data with the ignition on, and see whether it reads high even when at rest
- 3Look at the bypass valve connector for play, oxidation and loose connections
- 4Use a multimeter to check that the signal wire to the bypass valve has no contact with positive
- 5Check that the fuses are intact. Fuse locations are shown in the owner's manual
- 6If the fault remains, have a workshop check the bypass valve with diagnostic equipment
