Hva betyr feilkoden?
The engine control module (ECM) continuously monitors exhaust gas recirculation (EGR) and sets the fault when the flow through the system is too high. Although the code is named as insufficient flow, it therefore applies to excessive flow.
Mulige årsaker
- Damaged EGR valve
Hva du kan gjøre
- 1Check that the EGR valve can be fully closed and opened without sticking; dirt and soot can make it stick and set this fault
- 2Check that the EGR valve is not damaged
- 3If you have a diagnostic tool, read the EGR valve position at idle and when throttle is applied, and check that the value changes
- 4Read and clear the fault code, then road test the car to see whether it comes back
- 5After the EGR valve has been replaced or repaired, a workshop needs to carry out an adaption of it
Symptomer du kan merke1
- The Check engine (malfunction indicator) light comes on or behaves abnormally
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
