Testing the Tire Pressure Monitor System?
Does anyone know the specs for when TPMS will light up for low tire pressure? The other day I was showing my Son (and other Cubscouts) how to check tire pressure and how to fill up tires, so I purposely bled one tire down to about 22psi to see what the boys would do. Sure enough they found it was low, but before refilling, I took the truck out for about a 1.5 mile drive to see if the tire pressure monitor light would come on. Most the time I was driving <25 MPH, but I did get up to about 50MPH for a block or so. Nothing happened with the TPMS so I don't know if I let enough air out, or if it has to be low for a certain distance or speed before indicating low. Perhaps someone with the Factory Service Manual (or DVD's) can see how this is supposed to function.
BTW, we did fill the tire back up to the proper pressure.

Generally speaking I am very unimpressed with the TPMS on this truck. I've had issues with it the other way where you are driving along and it starts warning you of a problem when none exists. My opinion based on my experience with this vehicle is the system needs a lot of work. On my Honda it has never given me a problem.

there is an antenna built onto each valve stem that send the signal to the tpms processor.

Not to thread jack, but I recently had my tires/rims replaced and they transferred the sensors over, but unfortunately broke one of them. They replaced it, but they did not register the new sensor. Does anyone have the maintenance manual that tells how to register a new sensor? I know Chevy does a key cycle to enter the program mode, don't know about Ford.
