I'm brand new here, as of 15 minutes ago.
I just wanted to express my surprise and delight to find this forum. After a dozen or more years on the Internet I should think to do a WWW search any time I have a question on any subject. Sometimes it takes a while to occur to me.
I have a 2005 Highlander, purchased in January, 2004. It has 16K miles on it. (No snickering; I'm old, OK?)
I had my first flat tire last week. There was a time when I would have put the spare on myself, but why do I pay AAA dues if not to spare me the dirt and aggravation?
I took the flat to the only tire shop in this small, desert town and picked it up the next day. The spare is still on the car. (I was pleased to notice that the Highlander has a full-size spare. However, I'm not sure I could have found and deployed it without referring to the Owner's Guide.)
The TPWS light came on at some point after the spare was installed; I'm not sure when.
Due to the poor organization of the owner's manual it took me 20 minutes to find the information about re-setting the system. The illustration was so poor that I was looking for the button on the steering wheel ... then the dash below the steering wheel . . . finally under the dash, where I found it. Just those three little words, "under the dash", would have saved me another five minutes.
Imagine my surprise when the light came on again after about a half-hour of driving. Several re-sets have had the same result.
I'm due for regular service (I use the dealer in a nearby town), so I guess I'll let them handle it. However, I wanted to understand the system before dealing with them.
The two theories as to how the system works have me intrigued.
If an RPM sensor were used, then there would have to be some sort of averaging system to preclude the false errors when turning a corner.
I'm also wondering whether either system would be easier to design to handle over-pressure as well as under.

I would check to make sure the pressure in all 5 tires are at the right pressure. I'm assuming that the original flat was plugged, is now at pressure, and in the car, right?

Thank you all. This forum saved my day. Just had a yellow warning today morning. Google search lead me to this forum. And ban I found the nail.

The first time my tire light came on in my 4-cyl. FWD 2004 Highlander was about 4 years ago. My brother and I were in Indiana on the way to the east coast. Both of us searched for the reset button for a while before we found it. The problem was a nail and slow leak in the front passenger-side tire. After getting the tire fixed in Massachusetts, where I lived at the time, the light came on again. Discovered the tire shop had pumped 10 pounds too much air into the tire. At least on the Highlander I have, the system works by detecting one of the four mounted tires turning at a different rate. The light tells you that a tire is low, but it doesn't tell you which tire. There are other systems out there that do include the spare and actually measure PSI in each tire. It wouldn't surprise me if Toyota used it on more expensive models, and newer models.
