Early build 6.0's have the ICP mounted vertically on the rear of the engine block directly below the turbo.
You'll have to remove the heat shield that covers/protects the ICP sensor from the heat that's radiated from the turbo to get a visual on the sensor itself. This heat is the main reason the ICP fails. The plastic insulation on the sensor or sensor harness melts, allowing oil to seep out of the unit which causes a grounding issue or the harness shorts out.
There are 3 bolts that hold the heat shield itself on, none of which are real easy to get to.
Once that's out of the way, it's just a matter of unplugging the wire harness from the sensor itself and removing the sensor from the block. The sensor will accept a 1 1/16 deep socket or you can pick up the specialized wrench that fits from Snap-on, Proto, Mac......etc. Opening the hood on the truck outside on a sunny day helps a bit to illuminate the area.
Most often, you'll need to replace the oil soaked and/or melted wire harness along with the ICP sensor. Ford has a replacement kit that includes the new harness plug pigtail and a fabric heat sock to slide the sensor wires through to help prevent future failures.
