PCM Issues
 

Alrighty... I'm having ECM issues. Or as non-navistar related employees would say "PCM" so please forgive me if i use the two interchangeably.

I've got a 2003 Ford F-350 XLT 6.0L A/T 4x4 with an ICP sensor circuit intermittant code. The funny thing is, I've replaced the sensor, the plug on the wiring harness, and now all of the wires to and from the PCM, and I STILL have that P2285 code. Every connection I've made is high quality (soldered heatshrinked and wrapped). The PCM has no bent/broken pins, and the connections are all good. A while back I checked the ICP voltage with a multimeter at an idle and verified against Navistar VT365 Specs, and all was good. The truck keeps going into low power, (real sluggish), and that 2285 code comes up on my scanner. When it does, the PCM "assumes" ICP and operates the IPR by what it "thinks" it has for ICP. IPR % sits at 32% at idle with 2285 code active. When the truck is restarted and the code is cleared, the IPR % sits around 28%. So there is no ICP issue here. It's been leak tested three times within the last week by two different people and the HPO system is fine.

Which leads me to the PCM. I have a 3C3A-12A650-BDJ as a part number with an engineering code of DPU-232. My ford stealership wants $1,500 for a reman PCM. No. Fucking. way. They gave me a P/N of 3U7Z-12A650-FVHRM for said reman module

What I really need to know, is what is the difference between a DPU-232 and a DPU-232A or T. I cannot find a DPU-232 to save my ass. Every other PCM is an A or a T. I have found modules with the same exact part number, but a different DPU-###A/T. Then today I spoke with a used auto parts guy that told me that the last 3 of the OPN (Original Part Number) in my case the BDJ is superseded all the way up to BDM. What the hell does that mean. The guy didn't know and neither does my ford dealer.

Hopefully one of you will!

From my own experience the DPU needs to match as well as the plugs. I recall the auto transmission will use all three and a manual only uses two.

For $150 on Ebay it's worth a shot, you may need to have it programmed though.

Got the new PCM, a DPU-232A and replaced my DPU-232. Plugs in and runs, haven't had enough time to road test yet but it seems to have rectified the issue. Thank you HeavyAssault! Ill repost in this thread if the issue continues after programming.

What did it cost you for the "new" PCM?? Hope it all works out.

Still acting up... :DD: back to the drawing board...

$150 for the PCM

Could a power hungry VREF sensor cause this? I've been through everything I could think of. ICP Sensor, Harness, PCM. Im wondering if another sensor on the 5V reference signal could be eating all of the 5V reference voltage and not sharing power with the ICP sensor. That's the only thing I can think of but could it do that without throwing a code for that related sensor? :humm:

Wish I was smarter to give you more help. I'm not that versed on the codes and such.
