Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wheel chocks
Safety Warning: Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Repair Wiring

Remove the wheel and tire to access the wheel speed sensor.
Visually inspect the wiring harness for the left front wheel speed sensor for any fraying, corrosion, or breaks.
If damaged, repair the wiring using solder and heat shrink tubing or replace the harness as necessary.

3. Replace Wheel Speed Sensor

Tools Required: Torque wrench, socket set
Remove the bolt securing the left front wheel speed sensor to the wheel hub.
Disconnect the sensor connector and remove the sensor from its mounting location.
Install the new wheel speed sensor, ensuring it is seated properly.
Torque the mounting bolt to the manufacturer’s specified value (usually around 10-15 lb-ft).
Reconnect the sensor electrical connector.
