How do you fix the check engine light in a car?

Answer by  Amber40 (24961)

Start by reading the codes. You can buy a scan tool or have your local parts store scan it for free. Then simply fix the problem and clear the codes.

Check the codes using a code reader, or have your local auto parts store check the codes with a code reader; it'll let you know what needs to be replaced.

The best thing to do is to go to Auto Zone and they will hook up the computer to your obd and they will tell you what is wrong with it and then you will know what needs fixed.
