What Does The Check Engine Light Mean?

When this light turns on, it will either blink or stay steady, and this could mean a lot of different things ranging from a loose gas cap to an engine in serious danger. It all depends on what you see.

A yellow blinking light which in some models of cars can be orange or red means that the engine is in a bad state and needs immediate attention. A worst-case scenario of a blinking light is when the engine misfires to the extent that unburned gasoline is dumped into the exhaust system and this will cause excessive damage to the catalytic converter. This kind of damage is very expensive to repair. Under these instances, it is advisable to pull over and get in touch with an accredited and trusted auto repair shop.

In cases where the light is steady, the problem cannot be treated as an emergency, but never make assumptions. The check engine light is part of your car’s onboard diagnostic system, which ensures all the electronic systems are working properly. When it finds a problem in the system, that it can’t correct, it turns on the check engine light.

What can you do if you see the light on the screen? Read on for a few quick-fix solutions on what you can do if the light turns on.

A bad or a loose gas cap could be a reason the warning sign comes up. Try fixing the gas cap but it’s important to note that it may take a long distance drive (40 to 60 miles) before the light turns off.
