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

Where it lives

For P0C1E, the sensor sits on the circuit this code reports. The description of P0C1E reports a fault at the sensor.

Check these first

• An internal temperature sensor reading below its normal range
• A short to ground in the sensor circuit
• Low transmission fluid at the pump
• A blocked transmission fluid line

What to do next

1. Read the aux fluid pump control module temperature on a scan tool
2. Check the transmission fluid level
3. Check the fluid lines for a blockage
4. Test the internal temperature sensor circuit for a short to ground
5. Replace the pump control module if the reading stays low
6. Clear the code and retest
