OK, long story short. I had P2284 code on my scan gauge after replacing the oil cooler. I contributed it to air in the oil system. Sure enough, a few days of hard driving and the code went away.
Now a week later, I fired up my truck on a cold start yesterday morning. It's not that cold here(low 40's in the morning), but the oil started off at about 50F. Correspondingly, ICP at is higher, at around 1000(it's like this every morning until oil warms up). I usually let it warm up a tad before driving but yesterday I didn't, and hit the gas pedal a little hard once and the truck started acting like it does when you get this code. Sure enough, check scan gauge and the code is there. I drive home(about 15 minutes). A half hour later I start the truck up, check codes, and it's back to normal. Of course, oil temps were higher and ICP in the normal range between 580-590.
So is this normal? Since it doesn't trigger a CEL I assume it's more of a system parameters code?
Only other thing I can think of, if this isn't normal, is a mucked up IPR screen from when I installed my BPD oil cooler.

 

What type and grade oil do you have in it?
Also Ford OEM cap and filters ?

Also I can't post it right now my scanner is down
but I have the pinpoint tests that I will post in the afternoon.

Rotella dino 15-40 oil. Bulletproof diesel oil cooler and cannister filter(OEM filter a thing of the past).
If this is not a normal condition, then I will be leaning toward IPR screen. I originally had replaced my oem oil cooler with another oem oil cooler and it got clogged up instantly by sediment in the coolant. When I went to remove the clogged new oem cooler I noticed the HPOP screen had a bunch of muck on it that wasn't there the first time I replaced it(like it could have been FOD that was inside the oil side of the new cooler - soft tissue like fibers mostly, no metal chunks or anything like that). Well, the BPD oil cooler eliminates that crappy HPOP screen and incorporates its own that's built into the oil manifold so I made sure to REALLY clean that oil reservoir real good. But I fear that some of that fod could have still made its way to the IPR screen.
Having been on top of this engine for hours on end, twice in one week, though, I'm not looking to delve into the IPR unless all signs truly point right at it.
At this point, I'm thinking that if it was clogged and causing this code it would do it regardless of oil temp, so I'm not convinced I need to go there just yet.
BY THE WAY, THIS IS A 2006 F250, EGR DELETE, BPD OIL COOLER/FILTER, STRAIGHT PIPE(NO CAT) SCT TUNED WITH A CUSTOM STREET TUNE FROM INNOVATIVE DIESEL.

 

I read somewhere that a test you can do is to pull the ICP connector and see if the truck still starts? And if it does that means the ICP sensor is bad???
Well, I did that test when I first had this problem and the truck started right up and I thought, "Eurika, problem solved!" But I'm thinking I may have jumped the gun, as my understanding is if you have the p2284 code set, it's defaulting ICP value to the PCM to 500 so that the engine will in fact start, so disconnecting that connector really didn't tell me anything, did it? It seems to me that if it were a bad ICP that I wouldn't see ICP values on my scan gauge, or it would be stuck at 500.

 

Here's a link to the Ford diagnostic sheet for P2284. It's not normal to have this code: https://www.motorcraftservice.com/pu...15/V4C5074.HTM

 

OK thanks. It is intermittent and doesn't seem to be an immediate concern at this point. If it persists I'll throw an ICP at it, then check IPR screen, then check HPOP installation, as I did the fitting update and am wondering if I missed or otherwise damaged an O-ring during installation.
Logic tells me that it can't be shear coincidence that this code just showed up at the same time I did all this maintenance, so I doubt it's the ICP but that's the quickest and easiest fix so I'll go there first.
Methinks IPR fod most likely culprit, though. Just interesting I only get this code when the engine is cold.

 

.my guess would icp sensor or pigtail. Intermediate problems would kind of lean towards pigtail.

 

Icp to high. This after an oil cooler is more then likely a stuck ipr

 

Well, having had the harness removed and flopped over the radiator twice in the last month it is possible the pigtail got damaged. I'll look into it if it comes back. It's gone now.

 

Check the IPR screen. A too high code would not indicate a STC oring issue. Possible ICP but check the IPR screen. If it is partially plugged it would not be able to dump enough oil to drop the pressure to where it is desired.

 

I get the partially plugged concept, but why would the code only show up when cold? After the engine warms up, ICP is at 584, which is around normal. And IPR is at like 19%, if memory serves.
I'll probably have to make an evening out of taking the turbo back off and checking IPR. I know people say you can get to it by pulling the FICM and a bunch of other stuff, but it seems almost like more of a PITA that just pulling three bolts, three clamps, and a connector and being able to remove the IPR with a regular wrench instead of a special socket...

 

thicker oil and the same size obstruction. The thick oil will not flow through the IPR as well as thin oil.

 

true. guess I got something to do on my days off after this 15 day stretch...

 

what fixed your truck , mine is doing the same thing....
