Nothing about these trucks surprises me anymore, I still think it's whispering secrets at you. I just can't put my finger on it. Some bigger brains will happen along soon I hope. I gotta go make some money for the Company, If I think of anything, I'll chime in.......
Oh Yeah, and remember this, It's a electrical device (The ICP Sensor) I don't care if you just bought it for $500, It can and will crap out with no warning when you least expect it...

A little, Buying a new one couldn't hurt. But I would look closely at the wiring too, It's getting crispy on these old trucks. And the codes are telling you that the circuit is faulty. So check for loose contacts, cracked wires, chaffing, etc. Read up on procedures in AE on how to run logs. Because the ICP and the IPR are interrelated, if you run a log of just say, RPM, ICP, and IPR, pre repair, One of the Big brains here (Tugly for sure) should be able to give you some insight and some training on what to look for....going forward.

Well got it fixed. Changed out sensor all good. So I had no oil in the plug or in the sensor. It just went out. Truck runs better than it has in a long time. Icp was at 734 at idle but now went to 500-550 range.
