Transmission Fluid Temperature Sensor A Circuit Intermittent

Where it lives

For P0714, the circuit described runs through the sensor. The description of P0714 reports a fault at the sensor.

Check these first

• A temperature sensor with an internal break
• A loose connector that loses contact when hot
• Chafed sensor wiring near the transmission case
• Dirty fluid carrying debris to the sensor

What to do next

1. Monitor sensor A temperature on a test drive
2. Wiggle test the sensor and TCM connectors
3. Inspect the harness where it bends at the case
4. Replace the sensor if the reading jumps
5. Change the fluid if it is dirty
6. Clear the code and retest
