Your vehicle's Check Engine light helps alert you that there may be a problem in your engine, exhaust system, or battery and you may need automotive service. You may need help to decipher the cue because it's part of the OBD System. In modern vehicles, the OBD system monitors your emissions system and triggers the Check Engine light for a variety of issues, from the fuel cap to the catalytic converter.


Here are some quick tips on how to respond when your vehicle's Check Engine Light comes on:

  • If your Check Engine light is flashing, you should pull over and call for a tow service as driving could endanger your engine and catalytic converter.

  • If your Check Engine light is steady, have a mechanic examine the vehicle as soon as possible; there are many reasons the light may be on.

  • If your Check Engine light is still solid after your service appointment, it's OK to wait a few days to see if it turns off. If not, contact our University Auto and Tire team to make sure your vehicle's issue was resolved.

  • One possible quick fix: Check for a loose fuel cap. If the Check Engine light turns off after tightening the cap, you're ready to roll.
