Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Wiring and Connectors

Locate the Transmission Fluid Temperature Sensor on the transmission.
Visually inspect the wiring harness and connector for damage, fraying, or corrosion.
If damage is found, repair or replace the affected wiring and connectors.

3. Test the Transmission Fluid Temperature Sensor

Disconnect the sensor connector.
Using a multimeter, measure the resistance across the sensor terminals.
- Compare the readings with the specifications provided in the vehicle service manual.
If the resistance is outside specifications, replace the TFT sensor.

4. Replace the Transmission Fluid (if necessary)

If the transmission fluid is burnt or contaminated, drain the old fluid.
Refill with the manufacturer-recommended transmission fluid type (e.g., Honda ATF DW-1).
Ensure the fluid is filled to the correct level according to the service manual.

5. Reconnect and Reset

Reconnect the TFT sensor and ensure that all connections are secure.
Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any existing codes.
