Steve - Here is a post that explains how the sensors and the computer communicate with each other. The explanation is in post #2
Wrong tire readout on EVIC
Basically, there is nothing that can be "reset" by the dealer at all. If he does say he reset something, the odds are he just pulled you battery cable for a while and reconnected it. You might want to try that yourself, but be warned you will lose some of your memory type settings if you do that. If the system was working before you changed the sensors to the new rims, the software is probably fine. Just to make sure, and I know this is one of those questions that I just have to ask....are you sure the TPS were installed in your new rims? You can tell by looking at the valve stems sticking out of your rims, they should be a light gray in color. One other thing, if you put a chrome valve stem cap on there, it may be blocking the signals coming out as well. If you do have chrome valve stem caps, try taking them off and going for a spin.
Other than that, I'm outta guesses, but I hope you figure it out. I couldn't live with the annoying chimes and EVIC warning myself. Good luck.
