Possible Causes
WARNING: This page is about a different variant/trim than selected.
NOTE:
To monitor for too high temperature at the diesel oxidation catalyst outlet location; DOC/DPF component protection. Temperature sensor temperature above threshold (874.96° C)
- The powertrain control module measured a signal voltage above a specified range but not necessarily a short circuit to power, gain too high
- Overfilled DPF during drop to idle with active DPF regeneration on
- Blocked front face of DPF
- Stuck closed electric throttle butterfly valve during active DPF regeneration
- Other related DTCs
- Airpath
- Turbocharger
- EGR
- Fuel system
- Exhaust gas temperature sensor - Pre catalytic converter circuit short circuit to ground, short circuit to power, open circuit, high resistance
- Connector is disconnected, connector pin is backed out, connector pin corrosion
- Exhaust gas temperature sensor - Pre catalytic converter failure
