October Doesn't Have to be Scary: The Check Engine Light
One of the most vital components to a properly functioning vehicle is the 'Check Engine' light. It alerts the driver to a variety of potential problems based on the vehicle's onboard diagnostic system, and can seem like one of the most mysterious lights on your dashboard.
When the 'Check Engine' light comes on, it means that some system in your vehicle, including ignition, fuel injection or emission control, is not operating at peak performance, even if your vehicle appears to you to be running normally. The warning light generally indicates that the engine management computer has detected a malfunctioning fuel, emissions component, or a system failure.
Don't be scared if you see the light: According to the Car Care Council, a glowing 'Check Engine' light doesn't mean you have to immediately pull the car over to the side of the road, but it does mean you should get the car checked out as soon as possible. Ignoring the warning light could severely damage engine components and incur additional repair expenses.
