Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and safety gear.
• Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Wheel Speed Sensor

1. Remove Wheel and Brake Components:

   • Use a jack to lift the vehicle and secure it with jack stands.
   • Remove the left front wheel using a socket set.
   • If necessary, remove brake caliper and rotor for better access to the sensor.

2. Remove the Wheel Speed Sensor:

   • Locate the left front wheel speed sensor, usually mounted near the brake assembly.
   • Disconnect the electrical connector from the sensor.
   • Remove the sensor bolt (if applicable) and gently pull the sensor out of its housing.

3. Install the New Wheel Speed Sensor:

   • Inspect the sensor mounting area for debris and clean if necessary.
   • Insert the new wheel speed sensor into position and secure it with the bolt.
   • Reconnect the electrical connector ensuring a solid fit.

3. Reassemble Components

• Reinstall the brake rotor and caliper, tightening bolts to manufacturer specifications.
• Reattach the left front wheel and lower the vehicle.

4. Reset the ECU

• Reconnect the vehicle battery.
• Use the OBD-II scanner to clear the C0031 code and any other related codes.
