Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is turned off.
• Disconnect the negative battery cable to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensor

1. Locate the Wheel Speed Sensor:

   • Identify the wheel speed sensor location (usually mounted on the wheel hub or brake assembly).
   • Use a jack to lift the vehicle and secure it with jack stands.

2. Remove the Wheel:

   • Use a lug wrench to loosen and remove the lug nuts.
   • Take off the wheel to access the wheel speed sensor.

3. Disconnect the Sensor:

   • Locate the electrical connector of the wheel speed sensor.
   • Gently disconnect the wiring harness from the sensor.

4. Remove the Sensor:

   • Unscrew the sensor from its mounting position using a socket set.
   • Carefully pull the sensor out; if it’s stuck, use penetrating oil if needed.

5. Install the New Sensor:

   • Apply a small amount of anti-seize lubricant to the thread of the new sensor.
   • Install the new sensor in the original position and tighten it to manufacturer specifications (usually around 10-15 ft-lbs).

6. Reconnect the Sensor:

   • Reattach the wiring harness to the new wheel speed sensor.

3. Reassemble and Test

1. Reinstall the Wheel:

   • Place the wheel back onto the hub and hand-tighten the lug nuts.

2. Reconnect Battery and Test Drive:

   • Reconnect the negative battery cable.
   • Start the vehicle and take it for a test drive to ensure that the C1165 code does not reappear and that the ABS and traction control systems are functioning correctly.
