Description: Charge Air Cooler Outlet Sensor Signal Not Plausible
Troubleshooting:
DESCRIPTION:
This fault code sets when the Motor Control Module (MCM) detects that the charge air cooler
temperature is greater than 20°C (36°F) degrees from the expected temperature after the
engine has been turned off for 8 hours.
MONITORED PARAMETER:
Charge air cooler outlet temperature.
TYPICAL ENABLING CONDITIONS:
Key ON, engine OFF, battery voltage greater than 11.08 volts, engine rpm at zero, ambient
temperature less than 40°C (104°F), engine OFF for no less than 8 hours.
MONITOR SEQUENCE:
None
EXECUTION FREQUENCEY:
Once per cool down cycle.
TYPCIAL DURATION:
5 seconds
DASH LAMPS:
MIL
ENGINE REACTION:
25% derate, regen disabled.
VERIFICATION:
Road test the vehicle for 30 minutes until the coolant reaches operating temperature. Then
verify that the charge air cooler outlet temperature is within 15°C (27°F) of the intake air
temperature.
POSSIBLE CAUSES:
Damaged Charge Air Cooler outlet temperature sensor electrical connector
