I've never seen any cold hard facts about this but...
I got my new wheels and sensors a while back and still haven't programmed them yet. I've been too lazy to go down to ford. I still have my stock wheels in my garage at home. I don't get any warning lights in my car at all until I drive 30 miles (approximately) from home. then the light stays on, and shows when I start the car, until I return home and it picks up the original sensors again and the light turns off again.
It seems like it allows for no sensor communication for some time before it gives up on the sensor and throws a TPMS Fault.
