What You Should Know Before Resetting the Check Engine Light
Make Sure the Issue Is Fixed
Before resetting the light, you must ensure the underlying issue is resolved. It could be a loose connection that you’ve tightened or a faulty sensor that you’ve already replaced. If you reset the check engine light without fixing the actual problem, it may come back on after just 5 to 10 miles of driving.

However, if the code is still present condition, the problem must be fixed before attempting a reset. Otherwise, the light will return.
3 Easy Ways to Reset the Check Engine Light
Here are three easy methods you can use to reset the check engine light on your car.

After scanning, if the trouble code appears as a past condition, you can select “Erase Code” on the scanner. This will permanently erase the code and turn off the Engine light.
Method 2 – Disconnecting the Battery (Quick But Risky)
You can also reset the light manually by disconnecting the battery:
i) Turn off the vehicle.
ii) Remove the negative battery terminal.
iii) Wait for 90 seconds to 3 minutes.
iv) Reconnect and tighten the terminal properly.
v) Start the car and check if the light is off.
Note: This method is quick but may reset other vehicle settings.
Method 3 – Let the Light Turn Off Automatically
Sometimes, the check engine light turns off on its own after several driving cycles. If the problem was temporary, such as a loose gas cap or sensor glitch, the light may go off after driving and restarting the car a few times. Still, it’s a good idea to visit a service center and check the issue using a diagnostic tool.
