Learn how to diagnose and fix P0708 transmission range sensor issues in Volvo XC60. Step-by-step guide with diagnostic procedures and repair instructions.

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the vehicle battery to prevent electrical shorts.
• Raise the vehicle securely using jack stands.

2. Inspect and Replace Transmission Range Sensor

1. Locate the Transmission Range Sensor:

   • Find the sensor on the transmission case, typically near the gear selector mechanism.

2. Remove the Sensor:

   • Disconnect the electrical connector from the sensor.
   • Remove the mounting bolts using a socket set (usually 10mm).
   • Carefully pull the sensor out of its housing.

3. Install the New Sensor:

   • Apply a small amount of transmission fluid to the O-ring of the new sensor to ensure a proper seal.
   • Insert the new sensor into the housing and tighten the mounting bolts to the manufacturer's torque specification (generally around 10-12 Nm).
   • Reconnect the electrical connector.

3. Check Wiring and Connectors

1. Inspect Wiring:

   • Visually check the wiring harness leading to the transmission range sensor for any signs of wear, fraying, or corrosion.
   • Repair or replace any damaged wiring as necessary.

2. Test Connections:

   • Ensure all connectors are secure and free of debris.

4. Reconnect Battery and Test

1. Reconnect the Battery:

   • Reattach the negative terminal of the battery securely.

2. Clear Codes:

   • Use an OBD-II scanner to clear the P0708 code from the system.

3. Road Test:

   • Conduct a road test to verify that the transmission operates correctly and that the check engine light does not reappear.
