Safety Warnings

  • ⚠Disconnect the battery before performing any electrical repairs.
  • ⚠Allow engine components to cool before working on the transmission area.

Symptoms

  • •Check engine light illuminated
  • •Erratic or harsh shifting
  • •Vehicle unable to start (no crank)
  • •Transmission stuck in one gear
  • •Inability to shift out of park
  • •Transmission fluid leaks (if sensor failure caused damage)

Diagnostic Steps

  1. 1Scan the vehicle’s computer using an OBD-II scanner to confirm the P0708 code.
  2. 2Inspect the transmission range sensor connector for any corrosion, loose connections, or damaged pins.
  3. 3Check the wiring harness for continuity and shorts, particularly between the sensor and the transmission control module.
  4. 4Measure the resistance of the transmission range sensor with a multimeter according to the manufacturer’s specifications.
  5. 5Verify the vehicle’s battery voltage is within the normal range (12.4-12.6 volts) to ensure proper sensor operation.
  6. 6Test the sensor output while moving the gear shifter through all positions (P, R, N, D) to confirm proper functionality.

Solution

Solution

1. Preparation

  • Gather tools and parts.
  • Disconnect the vehicle's battery to ensure safety during repairs.
  • Ensure the vehicle is on a level surface and safely secured with wheel chocks.

2. Remove the Transmission Range Sensor

  • Locate the transmission range sensor on the transmission.
  • Disconnect the electrical connector from the sensor.
  • Remove the mounting bolts securing the sensor to the transmission using a socket set.
  • Carefully pull the sensor from its mounting position.

3. Inspect and Replace

  • Inspect the old sensor for physical damage or wear.
  • If the sensor is faulty, install the new transmission range sensor by aligning it properly in the mounting position.
  • Secure it with the mounting bolts to the specified torque (typically around 7-10 Nm, but verify with the service manual).
  • Reconnect the electrical connector ensuring it clicks into place securely.

4. Reconnect Battery and Test

  • Reconnect the vehicle's battery terminals.
  • Start the vehicle and let it idle.
  • Shift through all gears to ensure smooth operation and that the check engine light is cleared.
