However, with the check engine light, it will be extremely troublesome if, unfortunately, this indicator light fails because we will not be able to stop the lighting or reduce the annoying noise from this light.
If you are uncomfortable, the following article will certainly have little for you because the main content we want to bring today is how to disable check engine light permanently?.
What Is Check Engine Light?
The check engine light is also known as the malfunction indicator light (MIL). This part has a relatively simple structure with a small indicator light and sometimes elements to help make sounds.
Whenever the engine has a problem, the sensors inside the car will scan and send a signal from the protection system to the user through this small indicator light.
Although it may be small, the check engine light also plays an equally important role than other mechanisms such as SRS or the locking system because all of the above names must work well to drive safely.
Why Is My “Check Engine” Light On?
With the check engine light, when there is an error, this part will light up to notify us of the engine’s current problem so that there can be an effective remedy.
+Broken oxygen sensor
If you don’t know, an oxygen sensor is an electronic device installed inside a vehicle that helps you monitor the amount of unburnt oxygen coming out of a car’s exhaust. Through this device, we can get an overview of the amount of fuel consumed by the vehicle while moving.
And if the oxygen sensor is not working correctly, possibly due to some bugs, then reporting fuel-related problems will also lose stability. And as a result, false messages can occur.
+Fall sensor and module
If any modules or sensors responsible for monitoring and monitoring vehicle performance fail, the check engine light will also alert us. However, nothing will change even if the engine is standard, but the sensors fail.
+Liquid gas cap
Even if your gas cap is loose for some reason, the indicator light will flash. Because when the lid is not closed correctly, holes will appear from which the loss of pressure will occur and directly cause the gas to evaporate. And this amount of gas will be the signal for the indicator light to start.
+Ignition system malfunction
If there’s a problem with the ignition, there’s a good chance the check engine light will also light up quickly. Since we all know that ignition is an essential part of the operating mechanism of any car, there are many mechanisms to help measure and control the situation in this part.
How to Disable Check Engine Light Permanently?
To disable this part when a failure occurs, you can refer to some of the ways below.
+Drive and allow check engine light to turn off
It is the most straightforward implementation you can try first. If we use this method, we need to drive and ignore the trouble of the status lights.
During the vehicle’s operation, there is a high chance that the sensors on the car will check for problems, updating your vehicle’s performance on the road. After completing this process, the indicator light will turn off, and you don’t need to worry anymore.
However, if the problem persists for the next 3-4 days, you will need to use more specialized methods.
+Turn it on and off 3 times in a row
Today, most modern cars have built-in recovery mechanisms based on trouble codes embedded in the system. And similarly, there is a kind of code that does many things like turn off service ride control light or disable check engine light permanently. With the operation of turning off the check engine light, you only need to turn on and off the car three times in a row.
To do this, you need to put the key in the ignition and start the car in a few seconds. Immediately after that, quickly turn off the system and perform this on and off action three times in a row. The car will automatically restart and turn off the check engine light if you complete the above process.
+Detach and reconnect the battery
It will require you to access the interior of the vehicle, so please refer to the following instructions carefully
- Remove the latches securing the bonnet, locate the battery and use a wrench to disconnect the pre-connected positive cable on the power supply block.
- Temporarily stop the operation for 15 minutes to allow the battery to discharge less.
- Put the key in the ignition and start the car three times.
- Connect the positive cable, then close the capo
- Start your vehicle and wait a minute; the “check engine” light will turn off by itself.
+Removing the check engine light fuse
Unlike bleed abs, you may not need to use the scan tool. If you want to do this method, you will need an OBD reader.
And just like the impact on the battery, we also need to intervene deeply into the system through opening the bonnet.
- Remove the latches securing the bonnet.
- Then plug the reader into the available port on the vehicle
- Press “Enter” on the device to activate. The device will automatically start scanning your onboard computers for problematic codes if any.
- Press “Scroll,” and a list of commands will appear. Select the option to clear the incorrect codes by pressing “Enter” again.
Frequently Asked Questions(FAQ’s)
+For how long will the check engine light remain on even after repair?
The answer is that it takes about 3 days for the system to finish checking the condition of the vehicle.
+Is it mandatory to clear the codes even after repair?
It is best to delete it after the operation is done to prevent future damage.
+Does the check engine light turn off automatically?
Indicator lights will turn off by themselves if problems or conditions are with the right tools and methods.
+Is OBD easy to buy?
You can quickly get OBDs by buying them at auto repair shops.
Conclusion
Disabling check engine light permanently is not a complicated job, but it is still best to carefully refer to today’s article to get the most accurate information and experience.
