This check engine light video is a little long, but worth the time in my opinion. It provides a good overview of why the check engine light comes on. However, the focus is on a set code for a loose gas cap. Also included is how to use a scanning tool to find out what’s in the PCM memory.
The Haynes guide to on board diagnostic systems (available below) is a book that I own and recommend to people that want to learn more about automotive emissions systems, the modern on board automotive computer and how it operates.
You can learn strategies for diagnosis and repair of these check engine light systems and fix them yourself in some cases. Why would you want to fix the problem? You can’t pass State inspection when the light is on. Also when it comes time to trade in or sell the automobile privately the value will take a hit.
Note that I own many scan tools including the one shown in the above clip. I talk about the features and benefits of them on my dedicated page that provides automotive scanner reviews.
