## Will Unplugging Car Battery Reset Check Engine Light?
Unplugging the car battery is a common troubleshooting technique that can be used to reset the check engine light. However, it’s important to understand that unplugging the battery will not fix the underlying problem that caused the light to come on in the first place.
In most cases, the check engine light is triggered by a sensor or other component that is detecting a problem with the vehicle’s emissions system. Unplugging the battery will clear the code that is stored in the vehicle’s computer, but it will not fix the problem that caused the code to be stored.
If you unplug the battery to reset the check engine light, it’s important to have the vehicle inspected by a mechanic as soon as possible to determine the cause of the problem and have it fixed.
