tire pressure monitor in spare?

[shootist]

I called the dealer about my TPMS light staying on. I have checked all four tires and they are above 32 psi. The service guy said the spare tire may be low. Does the spare have a TPMS? It appears I can't add air to it unless I take it down.

I had mine down when I installed the back up system, I don't remember seeing one but I was not looking for it. Somehow I doubt it because the TPS only registers the 4 on the car and their locations.
