One for 1994-1995.5 with edge filter, and 1995.5 -2003 without edge filter. The earlier version is typically more $$ than the later version.
Is the newer version backwards compatible? I don't know.

Doesn't matter if they look the same, there are two P/N's for a Powerstroke IPR.

Well I'll put the other IPR back in then.
I noticed another connector in the engine valley, it is the same size and shape as the ipr connector. Where should that hook to? It was never plugged in before.

I will be waiting!
I'll switch ipr and see what that does. Then if its the same, I'll switch solenoids, I think those are the same. If that doesn't make any difference, I'll switch back to the original one.
I'll switch icps again and see what that does. I'm going to switch cps sensors also, just to see.
I'll try anything! I didn't make it to my snow plowing jobs this morning

Could be to your fuel bowl heater.

That's it! fuel bowl heater.
I switch IPRs, now the duty cycle is back to normal.
What are the chances it will do the same thing it did before, good for 150 miles, then back to this mess?

I was just going to go there because this is the exact symptom you would get. The EBPV activates when it's cold. If the EBPV connector was on the IPR, that would make some monster ICP when cold... but I don't see how it can run right when the engine is warm in this scenario.
Here's a picture, but I don't know if this is the one you can benefit from.

Got all my snow plowing done, truck ran great after switching the IPR solenoid. The ipr itself maybe be different, but I'm pretty sure all the solenoids are the same. Must be, truck ran fine.
The engine oil temp was running warm because the ipr was basically closed heating up the oil. Is that possible?
The highest EOT I saw today after switching ipr solenoid was 211, that seem okay for just plowing snow? It was about zero degrees out.
Once I got home I let the truck idle for 5 mins to cool down, when I shut it off the EOT was 197. Those numbers seem normal?

Just what I wanted to hear! everything seems perfect then.
Its just odd, the old motor I couldn't get it to 211 no matter what I did even on a 100 degree day. And this motor runs 211 when its zero out.
I used the oil cooler off my old motor too.
Oh well, I don't care as long as the truck is running good.
Just makes you wonder though.

The sad thing is that you can't purchase the coil alone....must come with the IRP assembly. (if anyone knows where to purchase the coil separately than I am all ears.....) ...

From my observations, I normally see EOT-ECT deltas of 5-10 degrees under light load conditions. Heavy load conditions can have deltas of 10-15 degrees depending on the situation. I would consider plowing snow to be a heavy load condition.

Hmm interesting, I wonder what caused the oil to heat up like that.
Maybe just a freak deal, if anything weird can happen, it will happen to this truck.
No, no place sells just the coil for the ipr

Turned the key on this morning, check engine light on, everything was blank on the scan gauge. You don't even want to know what I was thinking
I turned the key off then on, then everything read perfect! I had to haul a load of cattle out for a guy and the eot never got above 210, icp and ipr duty cycle was perfect.
I think its finally good to go
