What is what does it mean when the check engine light flashes?

When your check engine light is flashing, it's a serious warning sign that indicates a severe problem with your engine. Unlike a steady check engine light, a flashing light usually means there's a misfire occurring that could quickly damage your catalytic converter.

Here's what you need to know:

• Severity: A flashing check engine light signals an urgent issue. It's not something to ignore or postpone addressing.
• Misfire: The most common cause is a misfire, where one or more cylinders in your engine aren't firing properly. This means the air-fuel mixture isn't igniting correctly.
• Catalytic%20Converter%20Damage: Unburnt fuel entering the exhaust system due to a misfire can quickly overheat and damage the catalytic converter, a costly component to replace.
• Immediate Action: You should reduce your speed, avoid heavy acceleration, and get your vehicle to a mechanic as soon as possible. Continuing to drive with a flashing check engine light can lead to more extensive and expensive repairs.
• Possible Causes: While a misfire is the most likely cause, other potential issues include problems with the ignition system (spark plugs, ignition coils), fuel system (fuel injectors), or sensors.
• Diagnostic%20Testing: A mechanic will use a diagnostic scan tool to read the trouble codes stored in your vehicle's computer to pinpoint the source of the problem.
