Anytime I've set mine to zero the TPMS light comes on and won't go off. As said above I set mine to 45F/40R and leave it there. No warning light and if for some reason my wife is driving my truck and the pressure gets below the threshold the light will still come on.
I have mine set to 45 front/40 rear. It takes the truck a couple of minutes to clear the TPMS light when I change from $partan to P!P *SCTx4*. Why are you setting it to zero?
