If the light starts flashing when you are on the road or driving your vehicle, you need to pull over your vehicle. Look for a parking lot nearby or mechanic. If none is present, pull over on the side of the road, and call a tow truck.

While at same time, don’t take it too seriously. As the only real danger is if breaks don’t work! So you may, if choose, continue driving and book mechanic early as possible. Or can see the fault yourself via OBD scan tool.

It might cost you some money to have your car towed to the nearest mechanic shop, but it is in the best of your interest – it can save your vehicle from any further critical damage and the consequent costs.

Still thinking, what is exactly the issue with your car?

Whenever you come across a blinking check engine light, it could mean serious damage to your engine. Generally, the problem could be due to an engine misfire, and to notify you of this misfire, the light starts flashing.

An engine misfire feeds unburned fuel into the exhaust system of the vehicle, which can cause further damage.


When that happens, the temperature rises inside the vehicle, and the temperature of the catalytic converter can rise to dangerously unsafe levels, which can damage the parts of the vehicle. Further, this can cause damage to your pocket. And when I say damage to your pocket, trust me, you do not want to get into this type of trouble – paying bills for this extensive damage to the engine.

The longer you wait for anything to happen miraculously, the more is the probability of your vehicle getting severely damaged. Waiting longer to get it fixed will not do any good.

But if check engine light blinking happens when you do not want to waste your time on it, for example, if you are in the middle of a trip with your loved ones, then you cannot drive back to your home to find the issue and solution.

If you, still, are unable to figure out the problem with your vehicle, then a blinking check engine light can take the form of a serious issue. It is, therefore, important that you do not ignore the blinking check engine light even for a couple minutes.

It can also happen on a weekend when there will rarely be anyone available to help you out. If it happens on a weekend, it may be best to leave your vehicle in a safe parking zone until Monday.

Alternatively, you can call a towing truck, and get your car towed to home. When you think you can access a mechanic, conveniently, during the week, you can call them to repair your car.

The bottom line of the discussion is that it is necessary to take immediate actions regarding the blinking check engine light. Instead of waiting for getting your car serviced, you should stop driving it. You might be feeling unusual sounds or unusual feeling inside the car, so it is safe to get it fixed first.

You should keep a close ear to the sounds and movements of your vehicle every time you drive it so that you can know if there is something wrong.

If you know how the vehicle runs normally, you will find it easier to know when something is wrong with your car. Sometimes, you might be able to detect any possible issues with your car before the check engine light even starts blinking.

Generally, you can feel something is wrong with your vehicle when the check engine light starts flashing. The sound, the feeling or something might not feel normal about it. And it is time to get it fixed, before getting late.

The best solution in such case is to not ignore the flashing check engine light, and take immediate action to fix the issue with your car. Otherwise, you might cause greater damage to the vehicle.
