Description: Soot Sensor Regeneration Error
Troubleshooting:
DESCRIPTION:
Soot sensor fails to successfully regenerate and clear accumulated ash.
MONITORED PARAMETER:
Soot sensor heater.
TYPICAL ENABLING CONDITIONS:
Soot sensor enabled.
MONITOR SEQUENCE:
None
EXECUTION FREQUENCEY:
Always enabled
TYPCIAL DURATION:
Five seconds
DASH LAMPS:
MIL
ENGINE REACTION:
None
VERFICATION:
Verify repairs by using the diagnostic tool Soot Sensor Panel inspection routine.
NOTE: When the engine starts, the soot sensor will cycle through three modes: 1. Protective
heating of exhaust temperature dew point 210°C (410°F) to allow moisture to evaporate.
2. Heater active regeneration 800°C (1472°F) to clean soot.
3. Measurement mode for duration of key cycle.
POSSIBLE CAUSES:
1. Bent pins.
2. Spread pins.
3. Corroded pins.
4. Unseated pins.
5. Moisture in harness connector.
6. Faulty wiring.
7. Faulty soot sensor.

Description: Excessive Time to Enter Closed Loop Fuel Pressure Control
Troubleshooting:
DESCRIPTION:
Excessive time to enter closed loop fuel pressure control.
MONITORED PARAMETER:
Fuel rail pressure.
TYPICAL ENABLING CONDITIONS:
Rail pressure governor was previously operating in closed loop mode.
MONITOR SEQUENCE:
None
EXECUTION FREQUENCEY:
Continuous when enabling conditions met.
TYPCIAL DURATION:
15 seconds
DASH LAMPS:
1. MIL
2. CEL
ENGINE REACTION:

3. Fuel filter integrity (Loose Caps, Plugged Filters).
4. Fuel supply issues (Fuel Level, Fuel Aeration, Leaking Fuel Lines, Fuel Restrictions).
5. Intermittent loss of engine speed signal.
6. High pressure pump internal failure.
7. Fuel injector (Amplifier or Needle) leakage.
8. Fuel contamination.
9. Rail pressure sensor.
10. Motor Control Module (MCM).
11. External fuel leaks.
