Hva betyr feilkoden?
The ECM compares pressure readings from each side of the particle filter and checks that the sensor signal follows a calculated value. The code is stored when the signal is too high, meaning higher than the calculation gives. The fault concerns the signal from the particle filter pressure sensor.
Mulige årsaker
- Signal cable short-circuited to supply voltage
- Ground lead short-circuited to supply voltage
- Damaged particle filter pressure sensor
Hva du kan gjøre
- 1Read and note the code, clear it and road test to see whether it returns
- 2Look at the connector to the particle filter pressure sensor and make sure it is intact and fully seated
- 3Follow the signal and ground leads from the sensor and look for damaged insulation and places where a lead may have touched live voltage
- 4Use a multimeter to check that the cables are not short-circuited to supply voltage, meaning plus on the car
- 5If the cables are intact, have a workshop with diagnostic equipment check the pressure sensor and replace it if needed
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.
