Tire rotation: Does TPMS recognize tire position?

[jcdrotos]

I recently purchased a 2009 Yaris 3 door. In studying the Yaris owner's manual, I concluded that the TPMS system does not identify tire location. In other words, if a tire is low the warning light will go on, but it will not tell you which tire is low. If I am correct, it is then not necessary to re-program the sensors when tires are rotated (unless a sensor fails and is replaced).

My local Tire Kingdom/NTB sends me discount coupons that include a free tire rotation with an oil change. Since I got the Yaris, I happened to note that the coupon states that the free tire rotation does not include cars with TPMS.

I asked the dealer and, of course, they will gladly rotate the tires and re-program the sensors for $24.95.

Some brands of cars do have TPMS that responds to a low tires by telling you which tire is low. These cars would, of course, need to have the sensors re-programed when tires are rotated.

Is my thinking correct on this?
