ICP & IRP Sensor wiring harness

2002 Ford 250 Heavy Duty 7.3 Powerstroke (187,000 miles)


I have oil from the HPOP damaging the wires to the IPR and ICP sensors. The oil mist has been corrected but the wires to the various sensors are damaged. As I cut back the protective plastic tube, the oil seems to go on forever. Is there a complete wiring harness for all of these that would prevent me from splicing. I'm having problems locating a complete harness. Any link and suggestions are greatly appreciated.

What damage do you assume it's doing though? Oil in the wire isn't going to hurt anything and I would have thought the insulation would hold up to the oil.... Is that's what's wrong? Is the insulation degrading?

The wire is bubbling. On wet, rainy days, the truck will kill as the rpm's lower. (ex slowing to a traffic light)

OK, I don't mean to "Rain on your diagnosis" here, but that doesn't sound right to me....

You have "bubbling" insulation? And feel like the dampness of a rainy day (because up at the top of the engine, in the valley, certainly no water is getting to it) is causing the low voltage to "leak" and send the PCM misinformation that causes the engine to die? That seems pretty unlikely....

Unless the insulation is actually gone, and causing the bare copper wire to connect to ground or short with each other, simple humidity is going to have little effect, and would be just as likely to short on dry days too. High Voltage (like spark plug wires) might do that, but these sensor wires aren't going to.

I gotta think you've got other problems, unrelated to the condition you've found with those wires & a rainy day.

I have a problem and I can not figure it out. I have a 2000 f-350 7.3. I was driving it down the road and it was losing all power. I got to my house and it pretty much fell on its face. Then it died and now it wont start. What could cause this. I was told to check plugs under valve covers. As I did they were clean tight and plugged it. I was also told to check fuel filter which I did last night. That thing was nasty it was covered in rust. Replaced it and it still wont start. Should I and is there an easy way to bleed fuel lines to make sure there is no air. If this doesn't work could it be high pressure oil pump. I feel like it is working cause you can crank it over and the oil pressure gauge moves. Last thing could it be the cam shaft sensor? Can I use either to help it start or is that not smart. Thanks for advice in advance.

Check cps,also is your tach moving when you crank it? That will help determine if it's a PCM issue or not,any way to check vitals? ICP has to reach 500psi before injectors will even fire

5" side exit exhaust
AFE stage 2 intake
