DESCRIPTION:This code sets once the motor control module (MCM) detects that the outlet coolant temperature is above 112°C (234°F).

MONITORED PARAMETER:Engine coolant outlet temperature sensor.

TYPICAL ENABLING CONDITIONS:Always enabled

MONITOR SEQUENCE:None

EXECUTION FREQUENCY:Always enabled

TYPICAL DURATION:Two seconds

DASH LAMPS:1. MIL2. CEL

VERIFICATION:Outlet coolant temperature above 112°C (234°F) followed by one minute of idling.

NOTE: If codes 110-3 or 110-4 also active, fix those first.

NOTE: With a code engine, coolant inlet and coolant outlet temperature should be within 25 degree’s of each other. If not, replace both sensors.

Otherwise, most PROBABLE failures are:1. Low coolant.2. Thermostat failure.3. Blockage in radiator and/or charge air cooler.4. Fan belt failure.5. Fan shroud failure or installed improperly.6. Radiator hose failure (collapsed hoses).7. Engine fan failure.
