ICP on a 2003 Excursion

[allsuvswant2bme]

i have the sensor and the new pigtail. dealer says that old sensor was superceded by this new one that REQUIRES the new pigtail to work with the new sensor. does that make sense? only if the new sensor has a different shroud around the contacts, maybe???
before i replace either one, i want to be double sure it is not the EGR. i see the exact same symptoms posted by people with EGR problems. so, i unplugged my EGR while the engine was off, and nothing changed, still have the same issues. now, my question is this, knowing nothing is 100%, given my symptoms and the fact that it has a P2285 code (ICP), should i go ahead with the pigtail/sensor swap?

BTW, the pigtail comes as three purple wires with three butt connectors, not insulated, three pieces of heatshrink, loom, and some goo to put in the connector to resist moisture.?.? not a lot for $95!

thanks a bunch

what are your symptoms?.

[allsuvswant2bme]

rough, loping, surging idle that will knock off too. i get the surging at light throttle as well, at any speed. i have unplugged the egr and no difference was noticed. it's getting dangerous with the big surge at idle in sitting traffic. if you do not have all of the brake pedal, you can run over an import very easily!
let me know what you think.
thanks

one more thing, all three wires on the new pigtail are purple with no instructions. i have to assume that sensor pin to connector pin makes a difference???

p2285 yes is a icp circuit code , it could possibly be the sensor or the wire , as far as installing , just look at the original connector and hook the wire up accordingly , that will cause your concern , pcm not getting correct signal from sensor

when you remove your icp sensor you will find that is cover in oil. it toock a caca. replace the icp. the wire harness can be re used if is not shave. just make sure to clean the oil from it,if you decide to change it plug the connector in the icp thencut and splice wire by wire in the order of the plug.

thanks guys.
one more thing, is there a guide to this exercise? to me it looks like the ICP sensor has a wrap of kevlar or the like all the way to the block. i am going by the pics in the 6.0 bible. is there any way to do this without just laying across the driver side of the bay and reaching blindly for the three shield bolts? i think i have to remove the jug, but do i need to remove the ficm from the valve cover?
thanks again

If you are going to do it that way, you need remove the water jug, the ficm and a 10mm stud in the back that is the ground for the injectors. That way you can get your hand in there. You will also need to make a socket to fit and get the icp.

Or, you can get underneath the truck, take the heat shield off and with a wrench remove the icp. Both ways are a pain but it could be done.

my arms are not long enough to go at it from the bottom. just in case i need it, what antifreeze does this need, orange?
thanks

No, gold.
