Possible Causes
NOTE:
A customer may express a concern that the amber Diesel Particulate Filter (DPF) warning indicator is illuminated on the Instrument Cluster (IC) requesting a DPF regeneration. If the regeneration is not completed the DPF warning indicator will then turn red. The DTCs P2463-00 and P246B-00
will be stored in the Engine Control Module (ECM) memory
- The electric throttle air flow characteristics are incompatible with the engine calibration
- The powertrain control module is unable to command a motor, solenoid or relay, to move a piece of equipment to the commanded position either due to a failure in the actuator or its mechanical environment
- Excessive charged air pressure has been measured
- Other related DTCs
- Fuel injection related DTCs
- Exhaust system leakage
- Excessive engine oil level
- Excessive oil in the air induction system
- Air induction system leakage
- Charge air pressure sensor blocked
- Turbocharger system/vanes mechanical integrity
- Electric throttle system/blade mechanical integrity
