Hi Y’all, have a new to me 04 f250 I bought torn apart with a bad hpop. I was able to get it all back together with a new pump and didn’t start first try as scangauge showed my icp at 66psi when off and when cranking no change. I unplugged the icp and it fired up but smoking pretty good like unburned diesel and have a few codes: p2285 from icp being unplugged, p0266, p0270, p0673,p0677, and p132b.

if i step on the throttle it won’t go past about 2rpm, would this be due to the bad/leaking injectors?

wanted to see what y’all think before I start throwing money at it but leaning towards replacing two injectors for the two codes and new icp sensor.

thanks!

 

You may still have some air in the system. If you can, you need to get it out on the highway.

That said, are you getting any excessive white smoke (unburned fuel)?

 

After it started I took it down the block and it wouldn’t go past 10 mph with my foot on the accelerator pretty much floored, and definitely smoking a lot of white smoke that smells like unburnt diesel. The person I bought it from said they replaced all the injectors back in 2022. Thanks

 

Sounds like a poor quality injector (or injectors), or poor installation.

That said, where is your ICP sensor located - passenger valve cover or behind the turbo?

 

It’s an early 04 I’ve learned so located on hpop cover. Have it ordered and will pick up Monday from local ford dealer.

May bite the bullet and get two oem injectors too and swap them out.

 

ok so I've learned a whole lot and have dug more into this hitting a wall. I had the following codes: P2285( unplugged my icp as it showed 66psi koeo and no change when cranking), P0266, P0270, P0673, P0677, P132B.

I changed injectors on 2 and 4, added a new icp sensor(what a pain!) with ford oem parts from the dealer.

got it all buttoned up, cranked and fired up once, turned it off and didn't want to start and had the following codes: P2289, P0672, P0673, P0677. I checked the voltage of the icp with my scangauge and at koeo it reads 3270 psi and 3.84 volts. I unplugged it and plugged it into my old icp sensor and the volts are where it should be around .2 but still reads 66psi. does it sound like a bad icp sensor from ford? with the icp unplugged i was able to get it back on and idle for a while with these codes showing up: P0266, P2285, and the 3 glow plug codes.

its still smoking a good amount also, in park i can get it to accelerate, if i put it in drive it wont go past 1,000 rpms if the pedal is to the floor and smokes pretty good.

Thanks for any insight and help!

 

It could be a bad connect/pig-tail with an intermittent short.

P2285 is probably from start attempts w/ sensor unplugged.

Has P132b returned? That can indicate turbo control issues on 2003 engines and can have numerous root-causes (unfortunately).

When you try to accelerate, what do your ICP psi, ICP volts, ICP desired, and IPR numbers look like?

 

I thought about the pigtail but when i plug the old icp in and im twisting and turning it the reading is the same, when i plug into the new icp on the hpop cove it shows the psi around 3,000 and icv volts at 3.8. Will get a new pigtail to rule this out.

P2285 sounds correct as you stated as I have the icp unplugged to keep it running.

Code P132B was not back the last time I scanned it, I was watching vgtdc% and it was moving around from the 80 to 30 percent range. Turbo was replaced in 2022 as i was told and confirmed by sticker on it when i re installed it.

I will try it tonight once I get home, I have forscan and can monitor these points on my laptop and report back what I see in drive. I will not be able to see icp psi or volts or desired since i still have the issue with the new sensor reading high and have it unplugged.

thanks

 

At KOEO (Key-On, Engine-Off), there really isn't any way that you can have thousands of psi pressure in the oil system, so yeah - sounds like a bad sensor or an electrical short.

When you are running, the pressure might be high due to a sticking IPR valve, but you would just have to watch the data for that.

Just remember that the IPR valve % duty cycle is only a commanded value, it is not a real valve position.

 

got it. Yeah so definitely icp sensor or wire short as you state. Have you heard or had any issues with a new icp sensor from ford? I will order a pigtail and see what happens after that.

 

I haven't heard of any issues w/ Motorcraft ICP sensors, unless you are buying them off of EBay, Amazon, or even questionable places like Sinister ......

 

Might be worth it to bubble test the injectors as well

 

I tried this when I first got it all together and no bubbles in the fuel filter bowl. Just got home and found a schematic so going to see if there’s an issue with the wires.

 

Finally had time to look into it deeper, found I had no continuity to the ground leg of the icp pigtail, found the connector to it bad. I used a piece of wire and two crimp on connectors to re connect(new oem pigtail is ordered) to test and i had the correct reading at koeo, fired up and idling it reads ivp V. 1.05 and ipr% 26.17. Looks like this was the issue for this code and squared away. I do still have the glow plug code for cylinders 3 and 7 i will replace, along with code P2066.

I did notice on cylinder 2 it looks like there is diesel as its clear leaking from where the exhaust manifold meets the head, cylinder 2 has a new oem injector so not sure what's going on?

I do still have the issue where if i put it in D and with my foot on the break it wont go past 1,000 rpms if the pedal is to the floor, the last time I drove it it did the same thing moving but I didn't try driving it last night.

Thanks again for your help and any further insight!

 

no more codes and still have the no power/boost issue. If I put in drive and power break it, it barely tries to move, if I drive it have no power and barely gets to 1,000 rpm and won’t go higher. Have a boost gauge on pillar but does not move. Any help appreciated
