Why is my check engine light on?

The check engine light is one of the most vital components to a properly functioning vehicle. It alerts the driver of a potential problem on the vehicle’s on-board diagnostic system (main computer). When the check engine light comes on it means that a system in your vehicle — such as ignition, fuel injection, or emission control — is not operating efficiently, even though your vehicle seems to be running fine.If your check engine light comes on and it’s flashing, that indicates a more severe problem that should be checked out immediately to prevent damage to the catalytic converter (part of your exhaust system). When you experience a flashing light, minimize driving at high speeds, especially if you’re towing.When the check engine light comes on, there’s no need to panic, just make an appointment to get your vehicle checked out as soon as possible. Ignoring your check engine light could severely damage engine components and cost you more money in the end.

Q. Will it hurt my engine if I drive my car when the check engine light is on?

A. It is possible but not too likely. However, you do need to get your vehicle checked out as soon as possible. You may see a decrease in performance.
