Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.

2. Inspect and Repair Wiring

Tools Required: Wire strippers, soldering iron, heat shrink tubing
Inspect the wiring harness connected to the wheel speed sensor for any signs of wear or damage.
If damage is found, cut out the damaged section and splice in new wire, ensuring proper insulation with heat shrink tubing.

3. Replace Wheel Speed Sensor

Tools Required: Socket set, torque wrench
Disconnect the battery to prevent electrical shorts.
Locate the wheel speed sensor at the affected wheel (front or rear).
Remove the mounting bolt securing the sensor and gently pull it out from its housing.
Insert the new wheel speed sensor and secure it with the mounting bolt to the specified torque value (usually around 7-10 ft-lbs).
Reconnect the battery.

4. Clear Error Codes

Tools Required: OBD-II scanner
Use the OBD-II scanner to clear the C1141 code from the vehicle's computer.
Ensure all systems are functioning correctly post-clearance.
