Default 6.0 Knock Sensor Help

My 2004 2500HD 6.0 5 speed manual 150000 miles came up with the check engine light code p0332 knock sensor bank 2 low circuit. Removed the intake, cleaned everything up, changed the knock sensors, intake gasksets and wiring harness. Ill post the linkm to the kit i bought. The day of the installation the light was out went for a drive came home. Next day started the truck light was back on, even when disconnection the battery to reset the computer comes back on instantly, also clearing the code with a diagnostic computer comes on within minutes. I have checked all the wiring and not seeing anything unuasual, checked spark pluigs, oil pressure is good. I dont know where to head next.
I dont beleve there to be a EGR system on the 6.0 in 2004 and looked to maybe clean to clean it, i have also put the volt meter to the wiring and not getting any voltage at the knock harness connection
truck runs strong and not sure if i am hearing any engine noise or just hearing things in my head at this point.
I dont know what to try next, I suspect ECM but want to make sure before i pony up for another one, plus there has been no running issues
Any help, i have heard this is a common problem with the 5.3 and 6.0 motors

Proper test for k.s. is ohms,key off,disconnect harness,dvm at 400k ohm scale,they should show 93-107k ohms

thank you checked the ohms it was right at 100k.

you wouldn't know what voltage is supposed to go to them from the wiring harness.
I just swapped ECM and now the light is intermittent, would like to know voltage before I tear into the wiring harness for a short
