Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Inspect and Repair Wiring

Tools Required: Wire strippers, soldering iron, electrical tape.

Remove the undercarriage cover (if applicable) to access the TRS wiring harness.
Visually inspect the wiring for fraying, corrosion, or disconnections.
Repair any damaged wires by stripping back insulation and soldering the wires together. Use electrical tape to secure and insulate repaired areas.

3. Replace Transmission Range Sensor

Tools Required: Socket set, torque wrench.

Locate the transmission range sensor on the transmission housing.
Disconnect the electrical connector from the sensor.
Remove the mounting bolts securing the sensor using the socket set.
Carefully pull the old sensor out and replace it with the new one.
Reinstall the mounting bolts and tighten them to the manufacturer's specified torque (refer to the service manual for the exact torque value).

4. Reconnect Battery and Recheck Codes

Reconnect the negative battery terminal.
Start the vehicle and allow it to idle for a few minutes.
Use the OBD-II scanner to check for any remaining error codes.
