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.
Conditions for diagnostic trouble code (DTC):
1) The sensor signal is not rational
Observable symptoms
1) Regeneration not possible
Probable cause
1) Aftertreatment Diesel Particulate Filter (DPF) Atomization Module (Fuel Pressure regulator)
