Early Model S from 2012-2014(ish) don't typically display tire PSI on any screen-- but the sensors do read it and you can find all of them quickly by entering Service Mode. I demonstrate the newly available function as well as how to get in/out of Service Mode. Note that this appears to work with all Tesla TPMS systems and even generic sensors on cars running MCU2. MCU1 cars' functionality in Service Mode is more limited.

H/T to viewers @arrecife2 and @ExperienceCN who pointed out this addition to Service Mode to me.
