Was bedeutet der Fehlercode?
The engine control module monitors the control of the EVAP valve, and a signal that is too high is interpreted as a fault. The cause is a signal wire to the valve that is shorted to voltage.
Mögliche Ursachen
- Signal wire short-circuited to voltage
Was Sie tun können
- 1Read out the fault code, erase it and road-test to see whether it returns
- 2Switch off the ignition and unplug the EVAP valve connector. Check the connector for loose connections and oxidation
- 3Use a multimeter to check that the signal wire is not shorted to voltage
- 4Look for chafed wires that may have touched a live part
- 5If the fault remains, have a workshop with diagnostic equipment check the valve and its wiring
