Ok, are we getting distention amongst the ranks? Will the real definitive TPMS for dummies please stand up.
How does the system work? What is low tire pressure defined as...
25% of the total 4 tires or is it each tire individually.
why would there be a low and critical pressure sensor? Isn't one enough?
Is 26 lb the magic number for the predetermined threshold?

So many questions - is it just me?
