Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery to ensure safety.
Allow the vehicle to cool down if it was recently used.

2. Remove the Wheel

Using a jack, lift the front of the vehicle and secure it with jack stands.
Remove the left front wheel using a socket set.

3. Access the Wheel Speed Sensor

Locate the left front wheel speed sensor mounted near the brake rotor.
Disconnect the sensor connector by pressing the release tab and pulling it apart.

4. Inspect and Replace the Wheel Speed Sensor

Remove the sensor from its mounting bracket by unscrewing the retaining bolt using a socket set.
Clean the mounting area and inspect for any debris or corrosion.
Install the new wheel speed sensor in the same position as the old one, ensuring it is properly seated.
Reattach the sensor connector securely.

5. Reassemble and Test

Reinstall the left front wheel and tighten the lug nuts to the manufacturer's specified torque (typically around 80-100 ft-lbs).
Lower the vehicle from the jack stands and reconnect the battery.
Start the vehicle and perform a test drive to ensure the ABS and traction control systems are functioning correctly.
