Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shorts.
Ensure the vehicle is on a level surface and securely supported on jack stands.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, torque wrench, multimeter
Remove the wheel corresponding to the faulty sensor to gain access.
Disconnect the wheel speed sensor connector.
Clean the sensor area with brake cleaner to remove any debris.
Inspect the sensor for cracks or damage. Replace if necessary.

3. Check Wiring and Connectors

Visually inspect the wiring harness leading to the wheel speed sensor for any signs of wear or damage.
Use a multimeter to check for continuity in the wires.
Repair or replace any damaged wiring or connectors as needed.

4. Test Wheel Speed Sensor

Reconnect the wheel speed sensor connector.
Use a multimeter to check the sensor's resistance; it should typically be around 1,000 to 1,500 ohms (check the specific specifications for your model).
If the resistance is out of spec, replace the wheel speed sensor.

5. Reassemble and Reset Codes

Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.
Reconnect the vehicle battery.
Use the OBD-II scanner to clear any fault codes and reset the ABS system.
