What is what does it mean when your check engine light is blinking?

A blinking or flashing Check Engine Light is a more serious warning than a steady illuminated light. It indicates a severe engine misfire is occurring.

Here's what a flashing check engine light means:

• Severe Engine Misfire: The primary reason for a flashing check engine light is a significant Engine Misfire. This means one or more of your engine's cylinders isn't firing properly.

• Unburnt Fuel Entering the Exhaust: When a cylinder misfires, unburnt fuel is dumped into the exhaust system. This can rapidly damage the Catalytic Converter.

• Potential Damage: Continued driving with a flashing check engine light can lead to expensive repairs, particularly to the catalytic converter.

• Immediate Action Required: It is highly recommended to stop driving as soon as safely possible and have your vehicle towed to a mechanic.

• Possible Causes: Misfires can be caused by a variety of issues, including faulty Spark Plugs, ignition coils, fuel injectors, or vacuum leaks. A diagnostic scan is necessary to pinpoint the exact cause.
