During DPF regeneration the Aftertreatment Fuel Pressure Sensor monitors the fuel pressure rise and drop in the Aftertreament Hydrocarbon Dosing Module. During Air Purge the Aftertreatment Fuel Pressure Sensor monitors the air pressure rise and drop in the Aftertreament Hydrocarbon Dosing Module. The Engine Control Module (ECM) uses this input to determine if the system is operating correctly.
Observable symptoms
1) Regeneration not possible
Probable cause
1) Aftertreatment Fuel Pressure Sensor
2) Aftertreatment fuel shut-off valve
3) Aftertreatment Fuel Pump
4) Fuel supply lines from engine fuel system
