Does disconnecting battery reset check engine light?
The answer to this question depends on the reason why the check engine light is illuminated in the first place. If the check engine light is due to a loose gas cap or a faulty sensor, then yes, disconnecting the battery will reset the check engine light.
However, if the check engine light is due to a more serious issue, such as a engine misfire, then disconnecting the battery will not reset the check engine light. In this case, the check engine light will need to be diagnosed and repaired by a qualified mechanic.

How Do I Reset a Check Engine Light?
There are a few ways to reset a check engine light, but the most common method is to simply disconnect the battery for a few minutes. This will clear any stored codes in the system and turn off the check engine light. However, as mentioned above, this will not fix the underlying issue that caused the check engine light to come on in the first place.
If you’re looking for a more permanent solution, you can have the issue diagnosed and repaired by a qualified mechanic. Once the repair is made, the check engine light will reset itself.
Making Use of a Code Scanner
In some cases, you may be able to reset the check engine light by using a code scanner. This type of device is typically used by mechanics to diagnose engine issues, but can also be used to reset the check engine light.
Get an OBD-II code scanner or borrow one
Turn the ignition to the “On” position without starting the engine.
Connect the code scanner to the OBD-II port. The port is usually located under the dash, but may be in different places on different vehicles.
Follow the instructions that come with your specific code scanner to reset the check engine light.
Connect the scanner to the port beneath the steering wheel
Once it’s connected, you should see a message that says “Connected”
Choose the option to “Clear Codes” or “Reset Check Engine Light”
Follow the instructions on the screen to complete the process.
It’s important to note that resetting the check engine light does not fix the underlying issue that caused it to come on in the first place.
If you’re unsure about what’s causing your check engine light to come on, it’s best to take your vehicle to a qualified mechanic for diagnosis and repair. Trying to reset the light without fixing the underlying issue can lead to further damage to your vehicle.
Press the “read” button on the scanner and turn the key to the “on” position
Place your key in the ignition and turn the key to the “on” position. Do not attempt to start the vehicle. Turn off all car accessories, including the radio, once the dash lights come on. Then, on the scanner, press the “read” button to obtain the check engine light code. [3]
A string of letters and numbers will make up the code. Make a note of all the codes so you can figure out what they mean and make the necessary repairs to your car.
While some scanners identify or explain the codes, others do not. Look up the code in the owner’s manual or online if you don’t obtain a definition.
Turn off and disconnect your scanner’s key after pressing the “erase/clear” button
As long as the “erase/clear” button is pressed, the light will stay off. After you release it, the check engine light may turn back on if there are other issues with your car that are causing it to trigger.
If the check engine light comes back on after you’ve reset it, there may be another issue with your vehicle that needs to be addressed. In this case, it’s best to take your car to a qualified mechanic for diagnosis and repair.
Disconnecting the Battery
One of the most common ways to reset a check engine light is to simply disconnect the battery for a few minutes. This will clear any stored codes in the system and turn off the check engine light. However, it’s important to note that this will not fix the underlying issue that caused the check engine light to come on in the first place.
If you’re looking for a more permanent solution, you can have the issue diagnosed and repaired by a qualified mechanic. Once the repair is made, the check engine light will reset itself.
Disconnect the negative connection from the battery
Using a wrench or socket, loosen and remove the negative battery connection. This is usually the black cable with a minus (-) sign on it.
Drain the capacitor of any leftover electricity
After the negative battery connection is removed, wait a few minutes to allow any leftover electricity in the system to drain. This will help ensure that the system is completely reset when you reconnect the battery.
Reconnect your battery after 15 minutes
Once the system has had time to reset, you can reconnect your battery by tightening the negative connection back into place. Start your car and see if the check engine light is still on. If it is, there may be another issue with your vehicle that needs to be addressed.
What can you do before you reset your check engine light?

-The car is running rough
-There is a decrease in fuel efficiency
-The car is stalling or not starting
-There are strange noises coming from the engine
-The car is shaking or vibrating abnormally
Trying to reset the check engine light without repairing the underlying issue can lead to further damage to your vehicle. It’s always best to have your car checked out by a professional before resetting the light.
Check gas cap
One of the most common reasons a check engine light comes on is because the gas cap is not tight enough. This can cause fuel vapors to escape, which will set off the light.
If your check engine light is on, try tightening the gas cap and see if that turns off the light. If it does, you’re in luck! This is an easy fix that you can do yourself.
If the light doesn’t turn off, there may be another issue with your car that needs to be addressed. In this case, it’s best to take your car to a qualified mechanic for diagnosis and repair.

F.A.Q does disconnecting battery reset check engine light:
How far must you travel to clear the check engine light?
It is recommended that you drive your automobile 30 to 100 miles to ensure that the check engine light does not reoccur. As the various sensors need time to readjust, this allows the vehicle’s “Drive Cycle” to reset.
Is it possible for me to reset the check engine light on my own?
Turning the ignition on and off is an even easier technique to clear the engine management light. This method delivers the same result as the previous step, but without the battery being disconnected. Three times, turn the ignition on and off, waiting for a second between each cycle. The engine management light should turn off after a while.
I don’t have a scanner, therefore how can I reset my check engine light?
Disconnect the negative battery cable and wait a few moments to reset the check engine light without using a scanner. The diagnostic system in your car will be reset, and the light should turn off instantly if the underlying issue has been rectified.
