Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

• Tools Required: Socket set, multimeter, OBD-II scanner, wire brush, dielectric grease.
• Sub-steps:
  1. Remove the rear wheel to access the wheel speed sensor.
  2. Visually inspect the sensor and wiring. Clean any corrosion with a wire brush.
  3. If the wiring is damaged, repair or replace it as necessary.
  4. If the sensor is faulty (based on resistance measurements), unscrew the sensor from its mounting location.
  5. Install the new or repaired sensor and secure it firmly.

3. Reconnect Battery and Clear Codes

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear the C0051 code from the vehicle’s memory.
