Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Repair Wiring

Tools Required: Multimeter, wire strippers, electrical tape
Inspect the wiring harness for any signs of fraying or damage.
If damaged, strip the wires and splice in new wiring using appropriate connectors.
Secure with electrical tape to prevent future exposure to elements.

3. Replace Wheel Speed Sensor

Tools Required: Socket set, torque wrench
Locate the wheel speed sensor on the affected wheel (usually the front left or right).
Remove the bolt securing the sensor using a socket wrench.
Disconnect the electrical connector for the sensor.
Install the new wheel speed sensor by reversing the removal steps.
Torque the mounting bolt to the manufacturer's specifications (usually around 10-15 ft-lbs).

4. Reset the OBD-II System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any trouble codes from the system.
Start the vehicle and allow it to run to verify that the check engine light is off.
