I had the check engine light on for my 2003 Camry 4-cyl and took the car to AutoZone to get the codes read. They said it was P2238, but their online system did not have an entry about what that code meant because that kind of code was manufacturer specific.
Would a self-service device like this SAM be able to tell me anything about manufacturer specific codes or just the generic codes? I'm trying to understand why this device is worth $15 when AutoZone personnel will read the codes for me for free. If this device could tell me more information than the AutoZone people, then it would be worth the $15.
BTW, Brian R. at the AF Toyota thread already found the TSB for me that's related to my car's problem.
