Losing connection to TPMS sensors, already replaced

[JacobC1983]

Does anybody know the part number for the TPMS module for a 2020 GMC Sierra? I keep getting lost connection to my TPMS sensors, had them replaced and still getting the error. Happens after about 20 minutes of driving, and loses one or all of the sensors. 

Any help appreciated getting this fixed. Thanks

as stupid as this might sound, my 2020 front left sensor would lose connection randomly and i discovered that putting my phone in the cup holder caused it. i have the full console

Weird. Maybe I will try to turn off my phone and see if I still get the errors.

Make sure your back trailer tires are less than 23 feet from back bumper. I hade to move my module from behind the license plate to below of the bumpers. Longer trailers and fifth-wheels are a problem.

Are you running a Viofo A129 camera by chance?  Unplug the rear camera and watch the issue go away.  

If my wild guess is correct, the A139/A139 Pro won't have this issue

No cameras, no trailer. Removed radar detector. Still happening. What the heck is going on?!
