What is what does it mean if the check engine light is blinking?

A blinking Check Engine Light is a serious warning that indicates a severe engine problem is occurring. This usually means that unburned fuel is being dumped into the exhaust system, potentially damaging the Catalytic Converter.

What to do:

• Immediate Action Required: Stop driving as soon as it's safe to do so. Continuing to drive with a blinking check engine light can cause significant damage to your vehicle.
• Do not drive: Do not drive your vehicle any further than necessary. Call a tow truck to take it to a qualified mechanic.
• Get it Diagnosed Promptly: Have a qualified mechanic diagnose and repair the problem as quickly as possible to prevent further damage. They will likely use an OBD-II Scanner to retrieve trouble codes.
• Potential Causes: The issue is often related to Engine Misfires, ignition system problems (spark plugs, ignition coils), or fuel system issues.
