Hva betyr feilkoden?
The ECM compares pressure readings from each side of the particle filter and checks that the pressure sensor signal follows a calculated value. The code is stored when the signal is uneven or unreasonable. The fault concerns the sensor signal and can be caused by a poor connection or a damaged pressure sensor.
Mulige årsaker
- Contact resistance or oxidation at the connections
- Damaged pressure sensor for the particle filter
Hva du kan gjøre
- 1Read and note the code, clear it and road test to see whether it returns
- 2Check the connector to the particle filter pressure sensor for oxidation and loose connections
- 3Follow the wiring harness from the pressure sensor and look for chafing and pinch damage
- 4With a diagnostic tool, check the pressure sensor value in live data with the engine off. It should be low, and a value that jumps around points to the sensor
- 5If the connector and cable are intact, have a workshop with diagnostic equipment check and, if needed, replace the pressure sensor
Symptomer du kan merke2
- The check engine light comes on
- Poor performance, the car lacks power
Hva feilen kan påvirke1
- Engine output and speed may be limited
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
