Was bedeutet der Fehlercode?

Using the pressure sensor, the ECM monitors the difference in pressure across the particle filter. If the signal from the pressure sensor is judged to be incorrect, the code is set. The fault can be caused by hoses to the sensor that are swapped, pinched or loose, or by a clogged or damaged particle filter or a damaged pressure sensor.

Mögliche Ursachen

The hoses to the particle filter pressure sensor have been swapped
Pinched hose
Loose hose
Clogged or damaged particle filter
Damaged particle filter pressure sensor
Particle filter missing

Was Sie tun können

1Read and clear the fault code and check whether it returns
2Check that the hoses to the particle filter pressure sensor are not swapped and are on the correct connections
3Check that the hoses are not pinched, chafed or loose
4Check the connector at the pressure sensor for oxidation and play
5If you have a diagnostic tool, read the pressure in live data while you rev the engine and check that it rises
6Have a workshop check the particle filter and the pressure sensor if the fault remains
