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.
A flashing light requires more prompt attention, indicating a more severe condition that must be checked out immediately to prevent damage to the catalytic converter. When you experience a flashing light, minimize driving at high speeds or under heavy loads and get the car's diagnostics checked as soon as possible to prevent damage to your engine.
