What does it means when the car check engine glows?

When the check engine light illuminates on your car's dashboard, it indicates that the vehicle's onboard diagnostic system has detected an issue. This can range from minor problems, such as a loose gas cap, to more serious issues like engine malfunctions or emissions system failures. It's important to have the vehicle inspected by a mechanic to diagnose the issue and prevent potential damage. Ignoring the light can lead to decreased performance and increased repair costs.
