[TX Tundra 07]

It shouldnt be this complicated. The tire pressure sensors communicate to the computer via radio frequency right?

I went through something similar to this in my Chevrolet. You have to go through a sequence of events to get the computer to relearn where each sensor is.

On my Chevy it was something like the following:
1) turn the key on but dont start
2) turn the lights on and off 3 times, after the third time the vehicle horn will beep once
3) let the air out (or add air) of the front left tire until the vehicle horn sounds
4) go to the next tire clockwise (front right, rear right, rear left) and adjust air pressure until the horn honks for each one
5) turn the key off and the system good

There should be a sequence like this (I hope) for the tundra. I shouldnt have to take this thing back into the dealer with numbers on the sensors. If so, this will be yet another item on the list of things that pisses me off about the tundra.
