Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shorts.
Raise the vehicle securely on jack stands and remove the left front wheel.

2. Inspect and Replace Wheel Speed Sensor

Inspect the Sensor:
- Remove any dirt or debris around the wheel speed sensor area.
- Disconnect the electrical connector from the wheel speed sensor.
Remove the Old Sensor:
- Use a socket wrench to remove the mounting bolt securing the wheel speed sensor to the hub assembly.
- Carefully pull the sensor out from the mounting bracket.
Install the New Sensor:
- Insert the new wheel speed sensor into the mounting bracket.
- Secure it with the mounting bolt and torque it to the specification (typically around 10-15 ft-lbs, but refer to the service manual for exact values).
Reconnect the Connector:
- Reattach the electrical connector to the new wheel speed sensor ensuring it clicks into place.

3. Reassemble and Test

Reinstall the left front wheel and lower the vehicle back to the ground.
Reconnect the vehicle battery.
Start the engine and check for any warning lights on the dashboard.
