what does it mean if my Honda Pilot YF3 (2016-2022) has code C0031?

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface with the ignition off.
• Gather necessary tools and safety equipment.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensor

1. Locate the Wheel Speed Sensor:

   • Depending on the affected wheel (front or rear), raise the vehicle using a jack and secure it with jack stands.
   • Remove the wheel for better access to the sensor.

2. Remove the Old Sensor:

   • Disconnect the electrical connector from the wheel speed sensor.
   • Remove the mounting bolt(s) securing the sensor to the wheel hub or knuckle using a socket set.
   • Pull the sensor straight out from its housing.

3. Install the New Sensor:

   • Apply a small amount of dielectric grease to the O-ring of the new wheel speed sensor.
   • Insert the new sensor into the housing, ensuring it is seated properly.
   • Reinstall the mounting bolt(s) and torque them to the manufacturer’s specifications (typically around 7-10 ft-lbs, check service manual for exact values).
   • Reconnect the electrical connector.

3. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the vehicle and allow it to idle for a few minutes.
• Drive the vehicle at low speeds in a safe area to allow the ABS system to recalibrate.
