– Take your car to a mechanic: If you are not comfortable using an OBD-II scanner, it is best to take your car to a professional mechanic who can diagnose the problem for you.
2. Address the Underlying Issue
Once you have identified the error codes, you can begin to address the underlying issue. Here are some common causes of the check engine light and how to fix them:

3. Reset the Check Engine Light
After addressing the underlying issue, it is important to reset the check engine light to prevent it from coming back on. This can be done in a few different ways:
