Electric/Auxiliary Transmission Fluid Pump Control Module Internal Temperature Sensor Circuit High

Where it lives

For P0C1F, the circuit described runs through the sensor. The description of P0C1F reports a fault at the sensor.

Check these first

• An internal temperature sensor reading above its normal range
• A pump control module running hot
• A short to voltage in the sensor circuit
• A module that is installed or calibrated wrong

What to do next

1. Read the aux fluid pump control module temperature on a scan tool
2. Check the module vents and cooling
3. Test the internal temperature sensor circuit for a short to voltage
4. Check the module installation and calibration
5. Replace the pump control module if it runs hot with good cooling
6. Clear the code and retest
