Was bedeutet der Fehlercode?

The control module receives no signal from the EVAP valve in the evaporative emission system. The cause is an open circuit in the signal wire or the supply wire to the valve. Without a signal, the control module cannot monitor how the valve is working.

2Switch off the ignition and unplug the EVAP valve connector. Check the connector for looseness, contact resistance and oxidation
3Use a multimeter to check that the signal and supply wires to the valve have no open circuit
4Look for chafed wires to the EVAP valve, especially where they run near mounting points and moving parts
5If the fault remains, have a workshop with diagnostic equipment check the valve and its wiring
