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

A blinking engine light, also known as a blinking Check Engine Light (CEL), is a serious warning sign and indicates a severe problem that requires immediate attention. It usually signifies a Misfire that is damaging the Catalytic Converter.

Here's what you need to know:

• Severity: A blinking light is much more urgent than a solid, steady Engine Light.
• Misfire: The most common cause is a Misfire, which means one or more cylinders in the engine aren't firing properly. Unburnt fuel can then enter the exhaust system.
• Catalytic Converter Damage: This unburnt fuel can severely damage the Catalytic Converter, a costly component to replace.
• Immediate Action: You should avoid driving the vehicle if the engine light is blinking. Continuing to drive can lead to further damage.
• Professional Diagnosis: A blinking engine light requires immediate diagnosis by a qualified mechanic. They will use a scan tool to read the Diagnostic Trouble Codes (DTCs) and determine the root cause of the problem.

In summary, a blinking engine light is an urgent warning that requires immediate attention to prevent serious and costly engine damage.
