Let me rephrase that, The TPMS monitor the tire pressure and if the pressure on the door says 36psi that is what the sensors are programed for, If the pressure veries up or down to much it will turn on the light. GM's are pretty tight tolerance IIRC
4-6 psi in ether direction will turn on the light.
