Description: Fuel Temperature Signal Not Plausible
Troubleshooting:
DESCRIPTION:
This fault code sets when the Motor Control Module (MCM) detects that the fuel temperature is
more than plus or minus 20°C (36°F) from the expected temperature after the engine has been
turned off for eight hours.
MONITORED PARAMETER:
Fuel temperature
TYPICAL ENABLING CONDITIONS:
Key ON, Engine OFF, battery voltage greater than 11 volts, engine rpm zero, ambient
temperature less than 40°C (104 °F) ,ignition off for no less than eight hours.
MONITOR SEQUENCE:
None
EXECUTION FREQUENCEY:
Once per cold soak cycle.
TYPCIAL DURATION:
5 seconds
DASH LAMPS:
MIL
ENGINE REACTION:
None
VERFICATION:
Road test the vehicle for 30 minutes until the coolant reaches operating temperature.
POSSIBLE CAUSES:
1. Reprogramming or time change to the CPC.
2. Usage of an external or aftermarket heating unit
3. Damaged or corroded sensor connectors
4. Failed sensor
5. Damaged or corroded fuel temperature electrical connector.

EXECUTION FREQUENCEY:
Always enabled
TYPCIAL DURATION:
5 seconds
DASH LAMPS:
MIL
ENGINE REACTION:
None
VERFICATION:
Verify repairs by using diagnostic tool Soot Sensor Panel inspection routine.
NOTE: When the engine starts, 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. Damaged pins.
2. Bent pins.
3. Spread pins.
4. Corroded pins.
5. Unseated pins.
6. Signs of moisture in the connector.
7. Faulty wire.
8. Faulty soot sensor.

Description: Pressure Limiting Valve Staying Open
Troubleshooting:
NOTE: The pressure limiting valve will open when rail pressure is above 1150 bar. The Motor
Control Module (MCM) will command a lower rail pressure, trying to force the pressure limiting
valve closed. If the pressure limiting valve does not close, a fault code is generated. The
condition that caused the Pressure Limiting Valve (PLV) to open must be addressed.
DESCRIPTION:
Pressure limiting valve, failed to close.
MONITORED PARAMETER:
Pressure limiting valve.
TYPICAL ENABLING CONDITIONS:
RP closed loop control & RPM greater than 0.
MONITOR SEQUENCE:
