Although your vehicle doesn't talk, it communicates with you through messages, chimes, and icons. The check engine light of your car is something that you should not ignore. The purpose of this light is to warn if there is any possible problem with the vehicle that may require your attention. Therefore, you need to address the problem as quickly as possible.

There are times when the check engine light stays on even after repair. This constant lighting on your dashboard can be pretty distracting. Although it is too annoying, the problem is not that difficult to troubleshoot. If you are wondering how to disable the check engine light permanently, then with the help of a few techniques, you can reset the check engine light in the car.

Is It Safe To Disable Check Engine Light By Yourself?

Never underestimate the need to take care of your car. Every car is a complex construction and a combination of technologies. Everything has to run smoothly, and even the smallest breakdown can have serious consequences. Fortunately, today's cars are so smart that they have the ability to self-diagnose and can even tell the owner exactly where the problem is. Technology has come a long way, and you shouldn't ignore it. If you see the "Check Engine" icon on the dashboard, then you need to take action. Behind that symbol could be a loose wire in the ECU, or a faulty ignition or fuel system. Some malfunctions can be perfectly safe, while others can have catastrophic consequences for both the car and the driver. 

In addition to the unpleasant and distracting blinking on the dashboard, the "Check Engine" error imposes some restrictions on the vehicle, such as:

  • Maximum Power Limit;
  • Maximum Speed Limit;
  • Over-Fueling.

Because of this, many drivers try to fix this error prematurely, ignoring the root cause. We strongly recommend not doing this! Do not ignore the warnings of the car, fix the main fault, and the error will disappear on its own!

But if your car is in full working order, but the error has not disappeared - here is a list of actions you can take to permanently disable check engine light.

What Can Cause Check Engine Light Flashing In Your Car?

There are a few different things that could be causing your check engine light to flash. It could be something as simple as a loose gas cap, or it could be something more serious like a misfire. If you're not sure what's causing the problem, it's best to take your car to a mechanic and have them take a look. Often it is enough to fix the cause of the problem, and then you will be able to disable the check engine light. Next in this article, we'll talk about the most popular problems that cause the Check Engine icon to blink, as well as ways to solve them. We hope it will be helpful and that you will be able to fix this annoying bug. 

One of the most common causes of a flashing check engine light is a misfire. If one of your cylinders is misfiring, it means that the sparkplug isn't firing correctly and the air/fuel mixture isn't being burned properly. This can cause all sorts of problems, from decreased fuel economy to increased emissions.

If your check engine light is flashing and you're experiencing a misfire, it's best to take your car to a mechanic right away.

Another common cause of a flashing check engine light is a faulty oxygen sensor. The oxygen sensor is responsible for monitoring the air/fuel mixture in your engine. If it senses that the mixture is too rich or too lean, it will send a signal to the computer to adjust the fuel mixture. If the oxygen sensor is faulty, it can cause the engine to run lean or rich, which can cause all sorts of problems.

If your check engine light is flashing and you think it might be due to a faulty oxygen sensor, the best thing to do is take your car to a mechanic and have them check it out.

Finally, a loose gas cap can also cause the check engine light to flash. The gas cap is responsible for sealing the fuel system and keeping vapors from escaping. If it's not tightened properly, vapors can escape and trigger the check engine light.

If your check engine light is flashing and you think it might be due to a loose gas cap, the best thing to do is tighten it and see if the light goes off. If it doesn't, take your car to a mechanic and have them check for other potential causes.
