My source for track wheels and tires received proper TPMS sensors for my car from Porsche and installed them correctly. As they were awaiting pick-up by UPS to ship to me, one of them started beeping and continues to beep. My thought is there's a battery inside and it's low? I didn't realize there was the ability for TPMS inside the tire to beep - I thought it measured pressure and communicated that to the car and the car beeped.

Anyone have a theory on this? My guy of course is checking with Porsche in the morning, but I thought this would be an informative thread for the next guy that searches "TPMS Beeping" here at the forum

Edit to add photos of typical 2006 made TPMS. I don't see a method to change a battery...

I think they are powered by litjium ion batteries that should last 7-8 years. Didn't know they beeped though.

It's a sealed battery. Here' the manufacturer's web site - lots of info.
