Just out of curiosity, does the tpms system look at the tire pressures all the time? I put new wheels and tires on my jeep about a month ago, and just put regular valve stems on them, thinking I could turn the tpms off with my superchips programmer. well, turns out I can lower the pressure, but not turn it off with that. anyways, I drove around for a couple days with my old wheels and tires in the back till I had time to unload them and ofcourse my tpms light stayed out. I unloaded them and figured the light would come on right away, but I drove it for 3 days before my fiance called me and said the light came on while she was driving it. I thought that was rather odd that it took so long. Now every time I drive it it flashes that theres a fault since I don't have any sensors on it anymore.
