Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Inspect and Clean Sensor

Locate the left front wheel speed sensor on the knuckle assembly.
Remove the sensor mount bolts using a socket set.
Carefully pull the sensor out and inspect for dirt or debris.
Clean the sensor with brake cleaner and a lint-free cloth.

3. Replace Wheel Speed Sensor (if necessary)

If the sensor is damaged, proceed with replacement.
Install the new wheel speed sensor into its mounting location.
Torque the mounting bolts to the manufacturer's specifications (usually around 8-10 ft-lbs).

4. Check Wiring and Connectors

Inspect the wiring harness leading to the sensor for any frays or breaks.
If damaged, repair or replace the wiring as necessary.
Ensure connectors are clean and securely attached.

5. Reconnect Battery and Test

Reconnect the vehicle's battery.
Start the engine and test drive the vehicle to check if the ABS and traction control lights are off and that the speedometer operates correctly.
