I know there are hundreds of threads about the P2290 DTC, but I am not finding much with my exact symptoms. Brief background on my truck....2004 F350(11/03 build) 175K Miles, serviced every 4-5k miles with rotella 15w40 using motorcraft filter. fuel filters changed around 10k with motorcraft as well. fuel/oil caps are OEM. I went through an IPR valve and a HPOP about 10-15k miles ago. Bought the HPOP from Ford. Things have been great for many months since that repair until yesterday. I have run a street tune from MKM for like 3 years without issue. I monitor everything I can with SGII.

I was driving home from work and the truck was up to around 100*. I was going about 50mph and all of the sudden it just fell on its face. I pulled over, turned off ignition, restarted and it fired right back up with no issue. As I got back up to speed it lost power again. I held it at WOT and it hung at around 2k rpms. It was a hectic moment so I didn't check where my boost and other readings were.

I made it home and hooked up my SCT to pull codes. At first I had a laundry list of codes...most of which I believe set from the stalling at restarting of the truck while moving. I cleared the codes and went out for a few test drives to see which codes would come back.

I was able to repeat the failure and consitantly the P2290 showed. Truck would start fine cold and hot, idled perfect and generally ran fine. I seemed to be able to repeat the failure at WOT. Not every time, but sometimes at WOT the truck will cut out. If I let off the pedal (when the truck fails) and lean back into it it catches back up and runs fine.

I don't have time right now to post up all by SGII readings....but I looked/compared the standards compared to what I was reading hot last night and everything looked perfect (ICP, IPR%, FICM SYNC, EBP, MAP, ICV, ETC..). I checked those all at KOEO, LI, HI @ regular operating temps and they were all within spec.

My ICP pigtail looks good and the sensor itself is clean and dry. One thing I want to compare is the ICP actual vs ICP desired, but I dont know if SGII can be programmed for ICP desired??? From what I remember the ICP reading on SGII should be the actual.

I made it into work today no problems. I had a nice cold start at around 40* and when I got to work I was at full temperature. I shut the truck off and it restarted without issue. I did try returning my truck to stock last night and even then I was able to repeat the failure at WOT.

I know I don't have all of the specifics up at the moment, but I can get to that later. For the mean time I am just looking for ideas. I hope my HPOP isn't crapping out...but knowing my luck with this truck it isn't going to be something simple like a failing ICP or IPR.

 

Scangauge shows ICP Desired

Ok. Because when I was flying around last night trying to get it to act up I was monitoring the ICP with my SGII and at WOT it was only reaching 3075 on stock settings. I know before these issues it would climb up around 4000 with the street tune and the stock tune. Right after I hit that max reading on that run it cut out on me. Is there an x-gauge for ICP actual or is that only found when datalogging? I looked all over for a x-gauge different than the one that is listed in every thread with the standard 6.0l x-gauges. Thanks

Kind of wondering if I have a sticky/about to be compromised IPR valve. I might try and pull it tonight and see what the screen looks like. Right before my HPOP took a dump months ago I had a trashed IPR valve. Somehow I was able to start my truck after the initial engine stall with no hot start. I made it a week in WV driving hard in the hills and on my way back to MI the IPR failed about an hour from home. I had no hot or cold start. A new IPR fixed that and I was fine for a few months until my HPOP crapped out. We pinpointed the HPOP with the air test.

 

I think with the regular digital gauges only Dash Boss can do both ICP Actual and ICP Desired.

Well I am not going to say case closed yet, but ever since I returned my truck to stock and reloaded my street tune I haven't had any issues. After spending quite a bit of time looking through P2290 related threads I noted a couple threads that mentioned P2290 tripping @ WOT and the conclusion being a tune related issue.

I have only put on about 40-50 miles since I reloaded the street tune, but the truck hasn't acted up or thrown any codes. Last night I linked up my SCT to my laptop and did some monitoring with SCT's Livelink software. I was able to observe ICP actual/ICP desired/IPR% and they mated up fine. Now that I know I can do this I am going to take it on some road trips and see what happens.

Just based on this issue coming out of nowhere like it did and how everything is perfectly fine now I don't feel too confident that the issue is resolved. When I have more time I am going to check some of those common wire chaffing areas more closely. I still want to pull my IPR just to check out the screen for peace of mind. Any thoughts?

 

If your truck is in fact a 2004, it wouldn't be a bad idea to upgrade to the billet HPOP available since the 2003/2004 HPOPs are known to be weaker to begin with. Add a tuner that ramps up ICP demand and it isn't surprising that P2290 would set under high demand conditions. Where the billet HPOP is available from is what escapes me for the moment.

 

Yeah when I replaced my HPOP I looked into that...I think it was from dieselsite. They provide a stock output and an "adrenaline" high output billet HPOP. Price tag was around $1000 last I remember. I guess if my reman HPOP from Ford is on its way out again it is new enough that it should be covered under warranty and I would probably go that route. Although tuned and all I don't drive it like a 16 year old (typically). When the first failure happened a couple days ago I was just cruising along around 50mph, nothing out of the ordinary. Would you presume, based on what I have posted thus far, that my HPOP is on the fritz?

 

I wouldn't say it's on the fritz so much as it is that the OEM HPOP isn't able to supply the demand of your tuned strategy. I would just drive it on your stock setting for a while, while monitoring your ICP psi, ICP desired and IPR duty cycle data under the conditions described that will reproduce your symptoms. If the symptom stops, you likely need to upgrade your HPOP to the aftermarket higher output unit. If the symptom does re-occur on the stock setting, then yes get your truck in for a service replacement HPOP replace.

2004.5 - 2007 is in development.

 

That's what I was afraid of. When I returned it to stock the night it acted up I made a few passes around the block. It was feeling pretty good, but on one WOT run it fell on its face and popped the P2290 again. I guess I won't be taking the truck on any long trips in the near future. I know the people at my local Ford dealership pretty well, but I am thinking they might not honor the warranty since I did not have them replace it when it went out. Thanks for the replies.
