Any updates on this? I'm about to put on some aftermarket wheels but I also have a winter set. I would like to do this mod to get rid of the warning but the information seems to be conflicting. Can someone confirm?

TheNEWB seems to only be postulating that is measures the difference in atmospheric vs. tire but looking at the sensor, there is no apparent way it can, and he/she has not posted whether or not he/she has actually tried it.
Looking at the sensor itself, the stem is literally hollow metal with nothing else (the sensor being only what's inside the rim) functioning as the antenna. It's likely motion activated/linked to the abs sensors like the ones in some Jeeps are (which is why the pipe bomb doesn't work for them either), but bottom line is there is no workaround at this point.
Live with the light, it's just reflex to hold the info button now to clear the display on startup and whenever a door is opened. Not a big deal and not worth worrying about.

The thing works on movement.
So basically you'll have to by a small 4 bladed fan, I'd say about 6-8" in diameter.
Screw the tpms sensors onto the blades in the same orientation that they would be if they were mounted on the tire. Then secure the top of the armature shaft to a bearing. Put the entire thing into a round enclosure and seal the enclosure with a valve + gage on it
Pressurize the container to 35psi, turn the motor on, then start the car. The car should start receiving a transmission from the 4 sensors.
Or open up the sensor and try to wire it to transmit continuously. You'd probably want to then splice in like, a humongous battery since it'll always be transmitting. Or wire that up to a switch.

[QUOTE=Sparx123;9773092]How do you know that it runs off of movement?
Here's a nice writeup on TPMS that indicates it does indeed require motion to activate.

Otherwise the little sensor would be constantly transmitting and drain the batteries.
"On most systems, the signal is broadcast every 30 to 60 seconds when the vehicle is traveling faster than 12 to 15 mph."

So wait, the idea for this was that ONE tpms transponder in the car would fool FOUR tpms sensors located in the wheel-wells...or is there just one sensor that monitors the whole car? Seems kinda silly that this warning system would not be specific to the corner of the car where the low pressure tire is located. My wife's 7-year old Honda Pilot has a car pictogram and a warning light for each corner of the car so you know which tire is losing air. Just sayin'. Cheers.

The point still stands. 40 miles?! I would have noticed before the first. If it's designed for idiots, than they would tend to ignore lights to begin with.
