what does a check engine light mean?

Your vehicle’s check engine light is part of an onboard diagnostic system designed to alert you when something isn’t operating correctly. While the light may seem minor, ignoring it can lead to reduced performance, poor fuel economy, or costly repairs over time.

Whether the light is solid or flashing, our technicians can pinpoint the issue and help you decide the best next step.
