Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: OBD-II scanner, multimeter, socket set, wire stripper/crimper, torque wrench.
Parts Required: Replacement TFT sensor (if faulty), transmission fluid.

2. Replace TFT Sensor

Locate the Sensor: The TFT sensor is usually located on the transmission body.
Disconnect Battery: Safely disconnect the negative terminal of the battery to prevent electrical shorts.
Remove Electrical Connector: Carefully disconnect the wiring harness from the TFT sensor.
Remove the Sensor: Use a socket set to unscrew and remove the faulty TFT sensor from the transmission.
Install New Sensor:
- Apply a light coat of oil on the O-ring of the new sensor.
- Screw in the new TFT sensor and tighten to manufacturer specifications (usually around 15-20 Nm, check service manual).
Reconnect Wiring: Reattach the electrical connector to the new sensor.
Reconnect Battery: Reconnect the negative terminal of the battery.

3. Check and Top Up Transmission Fluid

Check Fluid Level: With the engine running, check the transmission fluid level using the dipstick.
Top Up Fluid: If low, add the recommended type of transmission fluid until it reaches the correct level.
