Hva betyr feilkoden?
The engine control module (ECM) keeps watch on the charge air cooler bypass valve and has received no signal from it at all. The cause is usually a poor connection or a break in the wiring, but the valve itself can also be faulty.
Mulige årsaker
- Poor contact, contact resistance or oxidation at the connectors
- Open circuit in the power supply to the valve
- Open circuit in the signal wire to the valve
- Faulty bypass valve on the charge air cooler (CAC)
Hva du kan gjøre
- 1With the ignition off, check the connector to the bypass valve for looseness, contact resistance and oxidation
- 2Use a multimeter to check the wiring to the valve for breaks while you move the harness
- 3Erase the fault codes, take the car for a test drive and see whether the code comes back
- 4If the code returns and the connectors and wiring are sound, have a workshop replace the bypass valve
Symptomer du kan merke2
- Car feels weak, lacks power or performs poorly
- Warning symbol and text message in the display
Hva feilen kan påvirke1
- Engine speed (RPM) may be limited
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
