Is There A Difference Between a Flashing Check Engine Light and a Steady Check Engine Light?

Virtually every driver on the planet has experienced a steady check engine light going on for no obvious reason. In most cases, if the vehicle is still running with no apparent problem, most drivers ignore the light.

There are, however, times when a check engine light is blinking and should not be ignored.

Here is what either type of check engine light means.

A Steady Light is a Warning

A steady light means something is wrong or about to go wrong, but it is not a dire emergency. It could be something as simple as a sensor going bad, which normally is an inspection issue and nothing more.

A Blinking Light is Bad

In most cases, a check engine light will shine steadily, a serious reminder that something is amiss in your vehicle. If the light is blinking, however, your minor annoyance and concern just got elevated.

If the check engine light is blinking, get to the nearest trustworthy mechanic you know.

What a Blinking Light Means

It could be overheating or an oil pressure issue. It could also be a problem with the brakes or fuel line, belt, hoses, etc.

By far, though, the most common is a misfire in the engine that can damage the catalytic converter. A catalytic repair is very expensive so addressing the blinking light not only might save your vehicle but could also save you a lot of money.

What to Do

The check engine light illuminates when there is a problem with your vehicle and a diagnostic test at a mechanics' is the only way to figure out what is wrong.

If the check engine light is steady, set an appointment with your mechanic for a checkup.

If the check engine light is blinking, get it to your mechanic as soon as you can. If you drive it, go slowly and if anything changes with your gauges or the performance of the vehicle, pull over and call for a tow.
