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 voltage at pin A14.EA:50 is more than 4.8?V Diagnostic operating conditions1) Ignition key in ON position Observable symptoms1) Regeneration not possible Probable cause1) Connector2) Open circuit on ground wire3) Short circuit to voltage supply, signal...
