Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and safety gloves.
Disconnect the battery to ensure safety while working on the electrical components.

2. Replace the Transmission Fluid Temperature Sensor

Locate the Sensor: Find the transmission fluid temperature sensor on the transmission housing.
Remove Electrical Connector: Carefully disconnect the wiring harness from the sensor.
Unbolt the Sensor: Use the appropriate socket size to remove the bolts securing the sensor to the transmission.
Install New Sensor: Position the new sensor and fasten it with the bolts, ensuring a secure fit (consult torque specifications for proper values).
Reconnect Wiring: Reattach the electrical connector to the new sensor.

3. Refill Transmission Fluid

Check Fluid Type: Ensure you have the correct type of transmission fluid as specified in the owner's manual.
Add Fluid: Use a funnel to add new transmission fluid through the dipstick tube until the appropriate level is reached.
Check for Leaks: Start the engine and monitor the area around the sensor for any signs of fluid leakage.

4. Clear Codes and Test

Reconnect Battery: Reattach the battery cable after all repairs are completed.
Clear Codes: Use the OBD-II scanner to clear the P0710 code.
Perform Road Test: Drive the vehicle to ensure that the transmission operates smoothly and the check engine light does not reappear.
