Thanks for the reply 04 4runner.
I am certain that mine is working as designed. I have been planning a wheel and tire upgrade for about 6 months now, and in that time I have been postponing patching a hole in one of my worn out tires.
Every 2 or 3 days, the light comes on the dash telling me that I have a low tire. The truck won't let me forget about it for sure.
I almost wish I didn't have this as well, but then again, I would probably have had a flat by now.
