Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to prevent any electrical shorts.

2. Inspect and Repair Wiring

Visual Inspection: Examine the wiring harness connected to the Transmission Range Sensor. Look for frayed wires, corrosion, or loose connections.
Repair or Replace: If any damage is found, repair the wiring using electrical tape or replace the damaged section of the harness.
Reconnect: Ensure all connections are secure and free from corrosion.

3. Replace Transmission Range Sensor

Locate the Sensor: Find the Transmission Range Sensor on the transmission housing.
Remove the Sensor:
- Disconnect the electrical connector from the sensor.
- Remove the mounting bolts using a socket set (typically 10mm).
- Carefully pull the sensor out of its mounting location.
Install New Sensor:
- Apply a small amount of transmission fluid to the O-ring of the new sensor to ensure a proper seal.
- Position the new sensor into place and secure it with the mounting bolts.
- Reconnect the electrical connector.
- Ensure the sensor is aligned correctly with the gear lever.

4. Reconnect Battery and Test

Reconnect Battery: Reattach the negative cable to the battery.
Clear Codes: Use the OBD-II scanner to clear the P0705 code from the ECM.
Test Drive: Take the vehicle for a test drive to ensure proper shifting and operation of the transmission.
