I'll have to do this next week or pop in Tomorrow (might be good day as it will be raining hard here). Should readings show up right away?
I did order a much better (pro model working with official kits) cable/Box for TechStream. The limits from my $15 cable should be resolved now and I will be on the current version of it.

A couple others chimed in but I didn’t see if you posted what brand and model number sensor they used for a replacement. I’m pretty sure they used the wrong one. The wrong sensor can still be programmed into the ECU and it will show up in TechStream. It will also read with a hand held scanner. It will give you the warning lamp when one tire drops pressure, but will not show the actual pressure on the dashboard. EVEN though you see the pressure in TechStream.

I had exactly the same issue with my 2014LS a year ago. Dealer said needs new sensors, batteries are dead. Didn't make sense to me (especially when the wanted $1250 to replace them all without even checking the status on Techstream). I got them all replaced at Discount Tire for $300 (OEM) and the problem went away.
