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 conditions
1) Ignition key in ON position
Observable symptoms
1) Regeneration not possible
Probable cause
1) Connector
2) Open circuit on ground wire
3) Short circuit to voltage supply, signal wire
4) Aftertreatment Fuel Pressure Sensor
5) Engine control module (ECM)
