Was bedeutet der Fehlercode?
The engine control module has registered that the signal from the EVAP valve is too low and sets the fault code. The fault is most likely a signal wire short-circuited to ground, or alternatively a damaged valve. While the fault is present, the control with two oxygen sensors is disabled.
Mögliche Ursachen
- Signal wire short-circuited to ground
Was Sie tun können
- 1Measure the EVAP valve resistance with a multimeter, or have a workshop do it
- 2Use a multimeter to check that the signal wire has no contact with ground (the body)
- 3Look for chafed or pinched wiring to the EVAP valve where it could have touched the body
- 4Repair the short circuit and clear the fault code
- 5Test drive the car to see if the fault code returns
Symptome, die Sie bemerken können1
- Malfunction indicator lamp (MIL) is on
Was der Fehler beeinflussen kann1
- Control with two oxygen sensors is disabled
