Why is My Check Engine Light Flashing?

When our check engine light comes on in the vehicle, the first thing we normally do is panic and wonder what’s wrong.

That is especially true if we are travelling and aren’t anywhere near our normal mechanic shop.

Some of us just ignore the check engine light all together and just hope it will go away one day.

With the technology that vehicles have installed in them nowadays, there could be dozens of reasons why the check engine light is illuminated.

What about if your check engine light is flashing?

When your check engine light is flashing, it’s basically screaming at you that you need to stop driving and get it serviced immediately.

And when I say immediately, I MEAN IT!

Pull over on the side of the road or in the parking lot and call a tow truck. It may be expensive to have them tow your car to the nearest auto repair shop, but it could prevent further damages from occurring to the vehicle.

But what exactly is wrong with my car?

A blinking check engine light could be signaling an engine misfire that dumps unburned fuel into the exhaust system.

If that happens, the temperature of the catalytic converter could be raised to a dangerous level, causing potential damage. Trust me, you don’t want to have to pay a bill on this type of repair.

And the longer you wait to get it fixed, the higher the possibility is for something to go severely wrong and cause major damage.

But that’s not the only reason why your check engine light could start blinking.

You could have a crack in the manifold gasket, a bad coil, a misfiring cylinder or other major issues.

You may be wondering if there’s anything you can do to fix your car.

If you’re highly experienced in working on vehicles, then there’s a chance that you can figure out what’s wrong and how to fix it by hooking up an OBD reader.

But if the check engine light starts blinking in the middle of a trip somewhere, then you don’t want to spend the time to drive back to your house to look into it.

If you haven’t already figured it out, a blinking check engine light is a serious thing and shouldn’t be ignored even for a few minutes.

The best thing you can do is go straight to the mechanic shop.

If it happens to be on the weekend when you notice it, your best bet may be to park in a safe spot and leave your car there until Monday.

Alternatively, just have your car towed to your home or straight to the mechanic shop that way it’s more convenient for you and/or the mechanic to access during the week.

The bottom line is you shouldn’t wait to get your car serviced if the check engine light is blinking. You probably shouldn’t even drive it, especially if it’s making an unusual sound or feels different in general.

Listening and observing the sounds and movements of your vehicle is something you should do every time you drive it.

If you are familiar with how it normally runs, then you will be able to easily determine when there is an issue. Sometimes you can detect something that isn’t quite right before the check engine light even comes on.

In general, you are going to hear or feel something very different about your vehicle when the check engine light is flashing.

The best advice you can take is to not ignore it and do something immediately to correct the problem!
