Hva betyr feilkoden?
The engine control module (ECM) monitors the EGR valve and performs an adaptation of it when needed. If the adaptation value is below the permitted level, meaning outside a predefined value, the fault code is stored. The fault can be caused by a short-circuited signal cable, a damaged position sensor or a damaged EGR valve. The code affects EGR control.
Mulige årsaker
- Signal cable short-circuited to ground
- Damaged position sensor
- Damaged EGR valve
Hva du kan gjøre
- 1Read the fault code, clear it and test drive the car to see whether it returns
- 2Check that the fuses are intact; their locations are shown in the owner's manual or on the fuse box cover
- 3Check the signal cable to the position sensor for breaks and chafing; with a multimeter, confirm that the cable has no contact with ground (the body)
- 4If you have a diagnostic tool: read the EGR valve position in live data with the engine running and see whether the value is below what is expected
- 5Have a workshop with diagnostic equipment check the position sensor and the EGR valve and carry out the adaptation
Symptomer du kan merke1
- No noticeable symptoms for the driver
Hva feilen kan påvirke1
- No exhaust gas recirculation (EGR) control
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
