Component Details:

Particulate filter, differential pressure sensor is mainly used to monitor the soot loading of a particulate filter on a diesel

engine or gas turbine.

Preliminary Checks:

1. Check whether the customer voice / view about the issue is matching with the fault effects mentioned in above

Table. If yes, go ahead with next steps. If not, check for other DTC’s presence.

2. Check whether other customers report similar complaints earlier. If yes, perform the preliminary checks with

respect to earlier issue closure.

3. Check for Damage in EMS ECU connector / Particulate filter differential pressure sensor.

4. Check for any back out of pins at EMS ECU connector / particulate filter differential pressure sensor.

5. Check for any damage of pins at EMS ECU connector / Particulate filter differential pressure sensor.
