You know if you keep your spare tires with TPMS next to the truck in the garage, when you start it up you have around 20min or so of driving before it does the recheck and notices the sensors arent with the truck anymore.
When you start it up if they are close (i keep mine on a rack next to where i park in the garage) it shows that they are all good to go! For me I drive to work and i get just near my office before sensor pops on. So maybe 20 miles worth.
Its an orange light.. who cares
