Help with ICP Volt values please
We'll I replaced my head gaskets with complete success. It took about four 8 second cranks and it fired right up as I watched icp build on scan gauge. It drove fine maybe a little rough for the test drive then the next couple days it ran smooth as can be. 100 mile trips each day. A couple days ago my CEL came on for p2285 icp low circuit. So I cleared it and it came back yesterday. My ICP ranges beautifully 650-1200 and my ICP volts seem to be fine .89 .91 at idle and 1.5-2 and IPR ranges fine too 22-40. This didn't happen before I did the head gaskets. I actually didn't even know where my cel was this whole time I've owned my truck til now. The wire harness was pull all the way out to the radiator when I did the work I don't know why I didn't inspect it. I also have a slight vibration while accelerating, don't know if this could be a symptom of a bad sensor. Are my ICP volts supposed to be higher?

ICP values look great, but the sensor could still be bad.
What does it read @ KOEO?
I would try:
Driving with ICP unplugged, improved inspect harness or replace sensor
No improvement:
Unplug EBP sensor and drive:
Improved? Same deal as ICP.
No improvement?
Inspect MAP hose and intake adaptor
