Selecting a good repair place

Turned on car, light is off.

The scanning, I am guessing, reset the light setting. Who knows.

If your gas cap is not on properly (or at all) your tank won't pressurize properly and this will mess up the sensors in your system, causing the code to trigger. It will usually take a few cycles of starting and stopping the engine (this means starting, running until fully warm so all the sensors go through all their positions, and then allowing to cool down) with the cap on properly to re-set the light. This has happened to me (my wife) a couple of times.

I don't think this was the problem. I'm not a gas cap amateur.

Well, it was just sort of me doing stream of consciousness. It was triggered by the comment about water in the tank. I know that once we thought the cap was on properly but the threads were crossed and this was the apparent cause of the problem. But I suppose that after 30+ years of filling gas tanks I might still be at the amateur lev4el. Oh well, at least your light is off.
