Circuit Description
Before active regeneration of the aftertreatment diesel particulate filter, a diagnostic test on the system is performed. The aftertreatment fuel injector opens and relieves fuel pressure in the line. The aftertreatment fuel pressure sensor must be reading atmospheric pressure at this point in the test. The aftertreatment fuel injector closes and the aftertreatment purge air actuator opens. This pressurizes the aftertreatment fuel system to vehicle air pressure. The diagnostic then checks to make sure the aftertreatment fuel pressure sensor is reading vehicle air pressure. The aftertreatment fuel shutoff valve then opens and allows pressurized fuel to enter the system. The aftertreatment fuel injector then opens and primes the system by purging the air from the line. The aftertreatment fuel shutoff valve and aftertreatment fuel injector then close and trap the fuel between the aftertreatment fuel shutoff valve and the aftertreatment fuel injector. The diagnostic checks to make sure the system maintains fuel pressure.
Component Location
The aftertreatment fuel injector is installed in the exhaust system in the turbocharger adapter pipe. The aftertreatment fuel pressure sensor and aftertreatment fuel shutoff valve are installed in the shutoff valve manifold. The aftertreatment purge air actuator is located above the shutoff valve manifold.
Conditions for Running the Diagnostics
This diagnostic runs during active regeneration of the aftertreatment diesel particulate filter.
Conditions for Setting the Fault Codes
The Engine Control Module (ECM) detected an internally leaking aftertreatment fuel shutoff valve, aftertreatment purge air actuator, or a stuck closed aftertreatment fuel injector.
Action Taken When the Fault Code is Active
The ECM illuminates the amber CHECK ENGINE lamp and/or the Malfunction Indicator Lamp (MIL) immediately when the diagnostic runs and fails.
Active regeneration of the aftertreatment diesel particulate filter will be disabled unitl the next key cycle.
Engine torque will be reduced if the engine is operated for an extended period of time with this fault active.
Conditions for Clearing the Fault Code
To validate the repair, start the engine and perform the INSITE™ electronic service tool Aftertreatment Diesel Particulate Filter Regeneration Test.
The fault code status displayed by INSITE™ electronic service tool will change to INACTIVE immediately after the diagnostic runs and passes.
The ECM will turn off the amber CHECK ENGINE lamp immediately after the diagnostic runs and passes.
For On-Board Diagnostics (OBD) engines, the ECM will extinguish the Malfunction Indicator Lamp (MIL) after three consecutive trips where the diagnostic runs and passes.
The Reset All Faults command in INSITE™ electronic service tool can be used to clear active and inactive faults, as well as extinguish the MIL for OBD applications.
Shop Talk
Possible causes of this fault code include:
Internal leak of the aftertreatment fuel shutoff valve allowing fuel pressure to leak past the shutoff valve
Internal leak of the aftertreatment purge air actuator
Stuck closed, plugged, or clogged aftertreatment fuel injector.
Possible Cause:
1) Aftertreatment Fuel Pressure Sensor failure
2) Aftertreatment Injector failure
3) ECM calibration
