Possible Causes
NOTE:
Diesel particulate filter temperature of the outer loop (post catalyst) is under temperature target
- Other related DTCs
- Exhaust gas temperature sensor - Pre turbine - Wiring integrity short circuit to ground, short circuit to power, open circuit, high resistance
- Exhaust gas temperature sensor - Pre turbine removed from gas stream
- Exhaust gas temperature sensor - Post catalytic converter - Wiring integrity short circuit to ground, short circuit to power, open circuit, high resistance
- Exhaust gas temperature sensor - Post catalytic converter removed from gas stream
- Air induction system leakage
- Diesel oxidation catalyst mechanical integrity
