Why Would Tire with TST Tire Pressure Monitor System Show Only 1 psi

Question:

I have had this system for about 2 years, changed battery today on one of the sensor now only gives a reading on 1 lb. I replaced with one of the other sensors. The wheel I moved it to worked great, but the tire that gave the 1 lb reading did it also with the different sensor? Help advice

Is it possible the valve stem was damaged on the wheel that only shows 1 lb when you removed the sensor? I'd try pressing the valve to see if it lets out air like normal. My guess is it's damaged or obstructed.
