The check engine light is just one of the many dashboard alert lights in your Chevy, but it’s one of the most feared and most frustrating. What does it mean? Why is it lighting up? What’s the right reaction? At Libertyville Chevrolet, we are here to help you figure out just what to do when the check engine light comes on. Learn more about check engine light diagnostic service here, and then come see why drivers from Mundelein, Arlington Heights, and beyond choose Libertyville Chevrolet for Chevy service.
The check engine light is essentially an alert from the ECU, or Engine Control Unit. This computer keeps tabs on the way your engine is running; if something isn’t happening the way it should, it will turn on this light and store a code. When you bring your vehicle to Libertyville Chevrolet for a check engine light diagnostic, our technicians will hook your Chevy up to a code reader that will decipher this code.
Your reaction should depend on what the light is doing. If the check engine light is flashing, that means that there’s a serious issue — usually a misfire. Since a misfiring engine can damage or destroy the catalytic converter, we recommend pulling over as soon as safely possible to help avoid this.
If the check engine light is solid, it means that it’s most likely not an emergency. The problem may negatively affect the fuel efficiency, emissions, or performance but is not likely to cause immediate serious damage, so you can keep driving to your destination. In fact, it may just be a loose gas cap, so be sure to check this! If it’s not the gas cap, schedule an appointment with us.
At Libertyville Chevrolet, our expert technicians will be glad to perform a diagnosis on your Chevy; when they find the cause of the problem, they will let you know so that you can approve of the repair. When they perform service, they will use only OEM and GM-approved parts.
When the time comes for your appointment, we make it easy with our online service scheduler. Once you’ve made your appointment, head to Libertyville Chevrolet. We look forward to taking care of you and your Chevy here!
