Unfortunately, it was a GM vehicle, and the trouble code was less than worthless, and caused an unnecessary repair to be done :( I guess that's the point I was thinking about, but didn't make. The trouble codes frequently lead mechanics to replace parts, even if that isn't the problem, and they get away with it, because "the computer told them to", and the customer pays.
