The problem could be minor, such as a loose gas cap, or it could be something more serious that requires repair or replacement of one or more parts. A trained technician will inspect your vehicle to determine what is causing the issue and how best to fix it.

If there is no problem with the vehicle’s emission system and you continue to drive with the check engine light on, your car will not be able to pass an emissions test.
