I've not read that the sensors transmit individual numbers. I think from my experience that it may be a simple "error/no error" signal, based on the set PSI.
The sensors actually do report individual numbers which can be seen with FORScan on a Windows laptop. So the NRG is reading and reporting them, just that they don't provide user access via either the dash displays or the center display.
