Car runs good no noise. Drives smooth. But the Trac Light stays on and the Engine light. Do you why that is?

This is caused by a bad wheel speed sensor most of the time, I would raise the car up and check the wheel sensor wiring because the wiring can get damaged by road debris. Here are the location of the sensor and how to check the system for codes.

If the wiring is damaged just fix it and the problem should go away, Check out the images (below). Let us know how it goes
