Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the battery to avoid electrical shorts.
• Allow the vehicle to cool if the engine has been running.

2. Inspect and Repair Wiring

• Tools Required: Electrical tape, wire connectors, multimeter.
• Inspect the wiring harness connected to the transmission range sensor.
  • Look for frayed wires, loose connections, or corrosion.
