2.2.221. SPN 4359, FMI 13, Particle filter upstream pressure sensor: Plausibility error during afterrun.ΒΆ

Description

The particle filter upstream pressure should be close to zero because there is no exhaust massflow in ECU afterrun.

Possible causes are:

  • The particle filter upstream sensor hoseline is defective.
  • The particle filter upstream sensor is defective.

Reaction in EEM

The FC is stored and the warning lamp is activated. The CAN message indicates an active fault.

NOTE: The present fault is classified as an emission related fault. Engine power is reduced after a certain time defined by an authority.

Solution

First save the error log and then obey the solutions that follow:

  • Examine the particle filter upstream pressures sensor hoseline for possible mechanical failure.
  • Examine the particle filter upstream pressure sensor installation and functionality.
  • Try the operation with another particle filter upstream pressure sensor to see if the particle filter upstream pressure sensor is defective.
