Coolant temperature sensor voltage is out of range.

Possible Causes:
1 Faulty coolant temperature sensor connections
2 Faulty coolant temperature sensor
3 Improper wiring
4 Verify controller calibrations

Diagnosis and Repair:
1 Faulty coolant temperature sensor connections
a Inspect the coolant temperature sensor and the engine harness connector pins.
a Disconnect the engine harness connector from the coolant temperature sensor.
b Inspect for corroded pins, bent or broken pins, pushed back or expanded pins.
c Inspect for evidence of moisture in or on the connector.
d Inspect for missing or damaged connector seals

e Inspect for dirt or debris in or on the connector pins.

2 Faulty coolant temperature sensor
a Check the resistance of the sensor
a Disconnect the engine harness connector from the coolant temperature sensor.
b Measure the resistance between the coolant temperature sensor signal pin and the coolant temperature sensor return pin.

3 Improper wiring
a Check wiring. Ensure wiring from the coolant temperature sensor is connected to the correct Aux 101 input.
b Check wires for breaks or abrasions.
c Check wires for moisture and debris at connection points.

4 Verify controller calibrations
a Using the display or the InPower Service tool, verify the calibration in the PCC control.
a If the calibration in the PCC control matches the latest calibration on the InCal website, then the calibration is correct. If it does not, update the calibration to the latest.
b Using the InSite Service tool, verify the calibration in the ECM.
a If the calibration in the ECM matches the latest calibration on QSOL, then the calibration is correct. If it does not, update the ECM to the latest calibration.
