2001 Silverado 12v on 5v reference

I am showing 12v on my 5v reference testing at tps,rough idle reduce engine power dtc p1515

Now I have 5v on all references,may have miss read while probing new code of p 1516,still in instant limp without even starting engine though it will start

I have and I seem to have everything except the yellow tac motor wire I believe #8 or#16 at the module I'm not getting a pulse at key cycle I do on brown wire,I'm not sure if I'm suppose to,I believe it works through reversing polarity to open/close blade. Just trying to not replace a working module,i have continuity through harness,thanks for reply

Ok I definitely didn't get the pulse at key cycle on yellow like I did when probed to brown,this was while I was working off gm flow chart. I had checked open or short on harness using ect3000 and only used multimeter for continuity and voltage, I will definitely put the meter on it and check that way too,thanks for that but I think this is going to be a module too thanks so much
