Step 4:

How to Reset the Check Engine Light by Disconnecting the Battery
Last but not least, you can reset your check engine light by disconnecting the car battery if you don’t have an OBD2 scan tool and you’re far from a nearby auto parts store. Although it’s not ideal and will reset your seat memory, radio presets, and clock, it’s not too difficult to do.
Locate the battery in your car. The majority of cars will have it beneath the hood, however others may have it in the trunk or anywhere else in the car.
The battery’s negative terminal should be disconnected. It will typically be colored black and marked with a (-) negative sign.
Connect the end of the negative cable that you just unplugged to the positive terminal of the battery that is still connected. The (+) positive symbol and the color red will be used to identify the positive terminal. Keep holding it for a minute. This will completely reset all of the car’s systems and drain all of its capacitors.
- Tech tip: Disconnect the positive cable end and touch the two cable ends together if you can’t touch the negative cable end to the positive cable end.
Reconnect the terminal end of the battery (s). If the positive terminal was removed, reconnect it first, then the negative.
Option A: Go to Autozone
Are you curious if your neighborhood Autozone can extinguish a check engine light? The answer is “yes,” but there are a few points to keep in mind:
- Local auto parts shops frequently offer to read your codes for free, but not all of them will turn off the light because of legal concerns. Some of them aren’t even equipped with code scanners for the check engine light.
- Whether or whether it is obvious that the components will cure your check engine light, salespeople are frequently encouraged to sell you items while you are at the store (and may actually be a waste of money).
Option B: Drive until the Light Goes Off
Even though it’s not advised, occasionally driving the car for a few days enables the car to perform a self-check. It will turn off the check engine light on its own if it determines that the issue has been fixed or is no longer a problem. You must identify and address the issue that is resulting in the code if the light returns.
This choice carries a risk even if it doesn’t cost anything or take any extra work. Driving on a car with a major issue for a number of days could seriously harm it. Always be cautious and ascertain the cause of your check engine light’s on-time as soon as you can.

What causes the check engine light to appear most frequently?

Pull aside and check to see if the cap isn’t loose or still on the roof of your car if your check engine light comes on right after you fill up. Sometimes the cap needs to be replaced, although it won’t have a significant financial impact. The majority of auto parts companies sell universal-fit gas caps for around $15.
