Drive Motor A Coolant Temperature Sensor Circuit Intermittent

Where it lives

For P0CC0, the circuit described runs through the sensor. The description of P0CC0 reports a fault at the sensor.

Check these first

• A loose drive motor A coolant temperature sensor connector
• Chafed wiring to the sensor
• A sensing element breaking down when hot
• Water in the sensor connector
• A sensor that reads off spec

What to do next

1. Road test and watch drive motor A coolant temperature
2. Wiggle test the sensor connector and harness
3. Heat the sensor area and watch for a dropout
4. Inspect the sensor wiring for chafing
5. Replace the sensor if the signal cuts out
6. Clear the code and retest
