So here is a question that just popped into my head. My tires were rotated last week. Where is the TPMS sensor and did the shop have to do anything to tell the car that the wheels moved? I’m getting readings in the car, but I’m curious if the car is reporting the pressures in the wrong positions now. Thoughts?

Pretty cool. Are TPMS bluetooth? Enough receivers in the car can determine which corner they are on? Don't know that I've seen a car that can determine which wheel is which without some human input or training.

There are several different types of TPMS; they're all radio based. The best ones use a sensor at each hub to pick up the sensor closest to it. The not as good ones use a central receiver to pick up the individual sensors. Whenever we get the tires on the Volt rotated they have to do a whole song and dance routine with some special programmer or they report in the wrong spot on the dash.
