Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and securely raise the front of the vehicle using jack stands.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace the Wheel Speed Sensor

Tools Required: Socket set, multimeter, torque wrench, wire brush, dielectric grease
Remove the left front wheel to access the wheel speed sensor.
Disconnect the electrical connector from the wheel speed sensor.
Remove the mounting bolt securing the wheel speed sensor and gently pull it out.
Inspect the old sensor for damage or excessive dirt buildup. Clean the sensor mounting hole with a wire brush if necessary.
Install the new wheel speed sensor in reverse order of removal, ensuring it is seated properly and the bolt is torqued to manufacturer specifications.
Apply dielectric grease to the electrical connector to prevent corrosion.

3. Reconnect and Test

Reconnect the battery.
Reinstall the left front wheel and torque lug nuts to the manufacturer’s specifications.
Start the vehicle and check that the ABS and traction control warning lights are off.
Perform a test drive to ensure proper function of the braking system and to verify that no codes return.
