ICP & IRP Sensor wiring harness

[hpdcsi]

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)

Bought this one for a van I just rebuilt, maybe they have a F-series one?

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.
