Hi all:
In the past, I've asked about the TPMS on the '07 Camry. This is because I wanted to put snow tires on a new set of wheels and didn't want to have to get the dealer to reprogram the car twice a year, switching the sensors each time. The local Toyota dealers seem to think that if you don't reprogram the IDs of the new set of sensors, that the warning light will stay on all the time. I didn't want to deal with new sensors so I decided to just get new wheels without sensors and live with the light on all winter. (I figured a piece of tape over the light would do the trick.)
ANYWAYS,,.... Not needed! I swapped the new sensor-less snow tires onto the car and the warning light does not come on! Apparently, the car only reports a problem if there are sensors in place and they detect a tire that is too low - not also missing sensors.
Of course, I'll have to monitor the tire pressure myself, but I've been doing that for over 30 years anyway.
Just figured to get this into the archives in case someone else wants to know how this works.
