I dont know where those sensors are located or how they connect from a

They can be quite handy to have. Tires, especially low profile don't
always tell you the actual pressure from appearance and I don't know
anyone that checks with a gauge every day. I had one go off on my
last car so I added some air. Next day, the tire did not look low,
but it was. The light tipped my off. Rather than put in more air I
went to the tire guy and he pulled out a big nail.

Out of the showroom, one tire showed a very slow "loss in pressure".
Could have been a defective transducer. But, more likely a rim leak, etc.

Brought car in to dealer ("Hey, YOUR TPMS is telling us the tire is losing
pressure; it's not my mishandling of a tire gauge!"). Initial test
showed the tire as good. Our insistence caused them to look at it longer.
Lady tech was tickled when she found it. Replaced the tire. No problems
in the months since then.
