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 less than 0.2?V Diagnostic operating conditions1) Ignition key in ON position Observable symptoms1) Regeneration not possible Probable cause1) Connector2) Open circuit, Supply wire3) Open circuit, Signal wire4) Short circuit to...

This diagnostic function monitors the systems ability to maintain and regulate the DPF temperatures within acceptable limits based on current conditions like normal operation or during regenerations. Conditions for diagnostic trouble code (DTC):1) Regeneration is active (by the relevant operation or by manual regeneration) for 15 minutes2) The aftertreatment hydrocarbon doser reached its upper fuel delivery limit for temperature adaptation3) Regeneration efficiency too low Observable symptoms1) Regeneration aborted Probable cause1) Aftertreatment exhaust gas temperature (EGT) sensors installed in the incorrect location on the aftertreatment diesel particulate filter (DPF)2) Obstructed/dirty aftertreatment hydrocarbon doser3) Catalyst failure, Possible excessive sulfur content in the...
