Have you ever been driving your Mazda 3 and suddenly the check engine light comes on? It can be a scary experience, especially if you don’t know what to do next. The first thing you should do is to try to figure out why the light is on. One way to do this is to use a diagnostic code reader to get OBD codes, which can help you pinpoint the problem. But with so many different codes, you might be wondering where to start.
