2018 flhx p2122 problem
ive been tackling a 2122 code for weeks, thought it was TGS and replaced it, code came back, went thru several diagnostics and concluded.it was ecu, apparently one of my tests was wrong because after i replaced that, the code came back,
I've did sensor power-1 circuit test,
TPS-1 circuit shorted test
TPS-1 circuit continuity test
TPS-1 circuit short to ground test
TPS-1 circuit short to voltage test
Sensor ground continuity test
TCA test
TCA sensor circuit test
TCA circuit circuit short to ground test
TCA power-1 circuit open test
TCA sensor test
ECM test
TPS-1 voltage test
TPS-1 circuit test
Sensor power circuit test
I'm using a centurion pro plus and I'm stumped, it's probably something I'm overlooking and i don't want to buy another component, has anybody else have these phantom codes, i would appreciate any input.
it's leaving me with a problem with TCA but don't want to just throw parts at it

i checked all the connectors and replaced a female terminal in tgs, using live graph on centurion super pro plus, the tgs seems to get voltage up to 5.2v, and momentarily to 5.3v, I'm not sure what is causing this because its a new tgs, and other tests led me to believe it was ecm, which was also replaced, pulling my hair out on this one, what could cause the increased in voltage and also the system is losing communication to ecm

Could also be caused by a bad connector, which might explain why you lose the power, check all connectors and apply some dielectric grease to them, and or loose, broken wires rubbing together..
