The spare has a sensor? First time I heard that. Since it's a compact spare and has about 60psi in it would the pressure monitoring system even handle it? The Pre-Delivery Service Bulletin PD019-06 dated March 17,2006 only references 4 transmitters. I know the system CAN handle a 5th but my guess is that's in case Toyota ever offers a full sized spare which at this time they don't. PD007-06 which only applies to conventional 07 Camry's specifically says a transmitter is NOT used in a compact spare.

OK - I stand corrected. My dealer told me that there were 5 and I never looked. I just checked and it has a molded rubber valve stem whereas the 4 main tires have metal ones. It appears that there are, in fact only 4. I don't expect the delivery guy would know everything about every model, but he also told me with certainty that the "auto" function of the headlight switch was only for the daytime running lights. And I knew that wasn't right. I guess I better check out everything else he told me
