Was bedeutet der Fehlercode?

Although the code is named signal too low, it applies when the signal from the particle filter pressure sensor is incorrect. The engine control module (ECM) measures the pressure upstream and downstream of the filter and checks the signal against a calculated value. The fault may lie in the hoses, which can be loose, pinched or swapped, or in the sensor itself.

Mögliche Ursachen

Loose hoses between the pressure sensor and the particle filter
Pinched or folded hoses between the pressure sensor and the particle filter
Hoses or pipes to the pressure sensor have been swapped
Damaged particle filter pressure sensor

Was Sie tun können

1Look at the hoses between the pressure sensor and the particle filter for loose, pinched or folded sections
2Make sure the hoses to the pressure sensor are not swapped round
3Check that the connections at the pressure sensor are firmly seated and free from contact resistance and oxidation
4If you have a diagnostic tool, read the pressure sensor signal in live data with the engine running and see whether the value is reasonable
5Have a workshop reset the adaptation; if the fault remains after a new service regeneration, the filter may need replacing

Symptome, die Sie bemerken können1

The engine warning lamp (Check engine) lights up or behaves abnormally
