The OBD codes will only tell you what is ultimately triggering in that chain of events. There may be a sensor or part upstream that is causing that code(s). That's why the home code readers are only so good. you can buy an expensive version, or see if you can get it read by someone with an appropriate reader.

Interesting. I was under the impression that a better OBD II scanner would tell you what those codes mean, so you do not have too google it. But I did not know that they can give you additional details. How does that work, are there additional codes that a less expensive reader cannot detect? Some ODB II readers are Bluetooth, and I imagine the iOS/Android software can read most of those codes. I could be wrong though.
The classic example of this is the "bad" O2 sensor, when many (edit: some) times that is only the result of a bad MAF.
