I did notice that when the dash light came on, it specified which tire and what the pressure was (26 lb.)
My 2010 Fit would only light up that I had a low tire..not which one or the pressure.

I think this is independent of whether your car gives you per tire info or just a warning that there's low pressure on on tire. I think/suspect the difference between per tire or one-of-the-tires warning systems is more about cost/feature.

DIRECT VS INDIRECT
Direct
attach a pressure sensor/transmitter to the vehicle's wheels. An in-vehicle receiver warns the driver if the pressure in any tire falls below a predetermined level. Direct systems are typically more accurate and reliable and most are able to indicate which tire is under-inflated.

Indirect
use the vehicle's anti-lock braking system's wheel speed sensors to compare the rotational speed of one tire versus the others. If a tire is low on pressure, it will roll at a different number of revolutions per mile than the other three and alert the vehicle's on-board computer. Indirect systems (except for the TPMS on several 2009+ Audi models and 2010+ Volkswagen models) are unable to generate accurate readings in cases where all four tires are losing pressure at the same rate, such as the effects of time and temperature.
