I bet if you disconnected the ICP, you'd get the same ^^^^^ thing. That tells me the ICP still isn't working. Could be the new sensor, or the wiring between it and the PCM.

I am going to clean, put new O rings and then swap in my spare IPR today. I checked the wires at the plug and moved them all around when it was running to see if it would act funny or clear up. I also tapped on the IPR in case it would free the plunger up. I will report back with results.

The truck wasn't at operating temp when I did the CCT, but it wasn't a cold start up either. It was probably 110-120 degrees. I will also look into setting up to read the EOT value.

The female plug looks like it is broken on the EOT sensor (I think it is the one on the back of the HPOP reservoir?) I am looking into getting another one just in case that was why the EOT codes were coming up at the beginning. I found a couple on Rockauto that look similar to it. Part # HP4400 or possible S612 for the pigtail plug:
