01 headache

[SouthernDiesel]

Maybe someone here can give me some input on this truck that's turned into quite a headache.

On cold crank runs fine, until the motor has run a while or driven about 30 miles or so. Then it starts running very rough, loosing about all its power.
I can pull over, let it set for about 10 mins and run it again (back to the shop)

I pulled over and run the codes while it was acting up, it came back
1280 ICP out of range low
1211 ICP not controllable pres above/desired
340 Cam shaft sesor circuit error bank 1/1 sensor
603 internal control modeule KAM error

Cleared codes, ran truck starting acting up again but with only 1280 showing.
I've replaced the Cam sensor (twice) all new injectors/rings less than 4k miles on them. replaced the ICP and cleaned all the wires (old one did have oil coming out of it) replaced BPS and tube.
Truck has fresh oil and filled correctly.
and the wiring has all seemed to check out fine.

And still runs bad after warming up with no smoke etc. and mainly shows the 1280 code (right now its running bad with no code showing.. go figure)

2001 F-250 7.3 powerstroke with superchip installed but on factory image.

any help would be GREATLY appreciated!!!

Update: I drove the truck again a few minutes ago, ran fine for about 10 mins then started the same thing. The only thing my Cornwell scan tool under drive option showed the snapshot of a 1211 code, everything else looked fine. (also the superchip is installed with a Micro tuner if that helps)

Maybe I can suggest a good match/ lighter fluid combination to the customer?


I've never had a 7.3 give me the run around like this one has!

have you had the ipr out?somtimes when the oil gets warm it will pass by the orings in the ipr,causing missing and power loss.just a thought,also are you getting any smoke when it starts missing and giving you power loss?I would put a oring kit on the ipr just because they are cheap.that ipr can cause lots of problems and not always picked up with a scanner.hope this helps some.

Also check the icp sensor, they can blow out the internals causing it to act pretty funny. All you have to do is unplug it and see if there is any oil sitting in the connector. The last one I did actually had a hole blown in the side of it and was ballooned out around the base.

[badazzstroker]

i think he said he replaced the icp already.

Oh your right. Missed that part of his post some how.

Yup, replaced the ICP yesterday, checking the IPR now, I may just replace it to be sure. I don't like guess work at someone else's expense though. But it may be money ahead with this truck. Also the customer (he failed to mention this to me before) said that he'd been burning vegetable oil in it from time to time, dunno if this could have been an issue or not. And i've not found any mods on the motor (nor am i familiar with the mods if any that needs to be done) I have heard once, not sure where that trying to burn un-moded can over heat the hpop and cause damage there? thanks in advance for the input and if i'd known about the veggi oil earlier i'd have posted about it.

[SouthernDiesel]

Well, not that I blame anyone, but i noticed that hardly anyone wanted to take a bite at this one

Anywho i've been doing a butt-load of research myself on it and since then i've came across some great info.
I've uploaded the info to a lil site i was gonna start soon (for diesel manuals, technical manuals etc...) maybe these will help others later, and maybe the link needs posted elsewhere, hope this helps people with ICP, IPR, HPOP, 1211, 1280 codes etc... (my issue on the truck was resolved btw, with the info here) Thanks to those that tried to help.
i'll add more manuals and make it all pretty as I go, so bear with me.

And update here as to what fixed the truck.

1. Fault in wiring going to the Cam sensor

2. The owner had failed to mention to me that he had been running used Cooking oil/gas mixture in the truck. Upon checking, ALL the fuel lines were gummed up, a thick black sticky mess in every one of them, removed flushed, flushed again, let soak, flushed after 3 days, finally acceptable.

3. the fuel bowl, O M G, is all i can say. is take a look. Everything on the whole fuel system was just as bad, Now what you think you see as the bottom ISN'T! there is about 3/4 of an inch deep of crap on the bottom.

A GOOD lesson for those that want to run veggie oil, but don't want to take the proper steps to run it! (expensive one too)

Cleaned everything, replaced O-rings on water/seperator drain (leaking)
repaired CAM wire Truck runs fine now .

Also, i've learned the 1211 code is normal for trucks that have Superchips installed.
Hope this helps someone!
