Transmission Fluid Temperature Sensor A Circuit Malfunction

Where it lives

For P0710, the part to look at first is the sensor named here.

Check these first

• Faulty transmission fluid temperature (TFT) sensor
• Open or shorted TFT sensor wiring
• Poor connector contact inside the transmission harness
• Internal transmission harness damage
• TCM fault

What to do next

1. Compare TFT reading with actual fluid temperature on a scanner
2. Inspect the transmission internal harness and connector
3. Check fluid level, since low fluid heats up the transmission
4. Test TFT sensor resistance against temperature charts
5. Repair the harness or replace the sensor as found
