Was bedeutet der Fehlercode?
Although the code refers to a faulty signal from the pressure sensor, it applies when the efficiency of the particle filter is too low. The ECM compares pressure readings from each side of the filter and stores the code when it detects this. The cause can be hoses to the sensor that are mixed up, kinked or loose, or a blocked or damaged particle filter.
Mögliche Ursachen
- Hoses or pipes to the particle filter pressure sensor are mixed up
- Kinked hose
- Loose hose
- Blocked particle filter
- Damaged particle filter
Was Sie tun können
- 1Read and note the code, clear it and road test to see whether it returns
- 2Check that the hoses and pipes to the pressure sensor are on the correct connections and not swapped
- 3Look for kinked, loose or cracked hoses and make sure they are fully attached
- 4Check the connector to the pressure sensor for oxidation and loose connections
- 5If the hoses are intact and correctly fitted, have a workshop with diagnostic equipment check the particle filter for blockage and damage
Symptome, die Sie bemerken können2
- The check engine light comes on
- Poor performance, the car lacks power
Was der Fehler beeinflussen kann1
- The engine may go into limp-home mode
