Hva betyr feilkoden?
The code concerns the position sensor A on the EGR valve and is set when the ECM finds the signal from it to be incorrect. The fault is described as an internal component fault in the sensor.
Mulige årsaker
- Position sensor has stopped working
- Damaged position sensor
Hva du kan gjøre
- 1Start the engine and read the fault status with a diagnostic tool if you have one: Fault found means permanent, No fault found means not active now
- 2Check that the connectors to the position sensor are firmly seated and not oxidised
- 3Use a multimeter to check that the wires to the position sensor have no break and no contact with ground (the body)
- 4Switching the engine off erases the stored fault status, so the test has to be redone
- 5If the fault remains, have a workshop check the position sensor
Symptomer du kan merke1
- No noticeable symptoms for the driver
Hva feilen kan påvirke1
- EGR control is lost
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
