how to troubleshoot C1231 error code on Honda Civic 11th Generation (2022-Present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the ignition is off.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Repair Wheel Speed Sensor
