Hva betyr feilkoden?
The code shows that the car has for some time been driven in a way, for example slowly or mostly in city traffic, that has not allowed a successful regeneration of the particle filter. It is an early stage of the filter becoming blocked. The code is stored when the particle filter is blocked or clogged.
Mulige årsaker
- The car has been driven a lot in urban environments
- Damaged particle filter pressure sensor
Hva du kan gjøre
- 1If other codes are stored in the engine control module, fault-trace them first, since they can cause the same symptoms
- 2Remedy the connector at the particle filter pressure sensor if it is loose or oxidised, since contact resistance gives a wrong signal
- 3If you have a diagnostic tool, read the particle filter pressure sensor value in live data and see whether it stays at the same level while the engine runs
- 4Avoid slow driving and city driving for a while and drive on country roads so the filter can regenerate
- 5Have a workshop regenerate the particle filter if the fault remains
Symptomer du kan merke2
- The Check engine lamp may come on or behave abnormally
- The car may feel weak or lack power
Hva feilen kan påvirke1
- Engine output and speed are limited
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
