Your check engine light can come on for a multitude of different reasons. When your vehicle’s computer finds a component is not performing in line with preset specifications, it can return an error code. This can mean everything from a loose gas cap to an engine that’s misfiring. The most important thing is to get your vehicle in for a service appointment as soon as possible to let our ASE-certified mechanics see what’s causing the check engine light error code and to fix the issue.
