Description: Soot Sensor Temperature Rationality Failure – Cold Start
Troubleshooting:
DESCRIPTION:
Soot sensor temperature and select catalyst reduction temperature sensors do not match when
cold.
MONITORED PARAMETER:
Soot sensor temperature, SCR outlet temperature.
TYPICAL ENABLING CONDITIONS:
Soot sensor enabled.
MONITOR SEQUENCE:
None
EXECUTION FREQUENCEY:
Always enabled
TYPCIAL DURATION:
5 seconds
DASH LAMPS:
1. MIL
2. CEL
ENGINE REACTION:
None
VERFICATION:
Key cycle; perform diagnostic tool soot sensor panel inspection routine.
NOTE: When the engine starts, soot sensor will cycle through three modes: protective heating
of exhaust temperature dew point 210°C (410°F) to allow moisture to evaporate, heater active
regeneration 800°C (1472°F) to clean soot, and measurement mode for duration of key cycle.
POSSIBLE CAUSES:
1. Damaged pins.
2. Bent pins.
3. Spread pins.
4. Corroded pins.
5. Unseated pins.
7. Faulty wiring.
8. Faulty SCR outlet temperature sensor.
