powerstroke, i am a diesel tech at a ford dealer and once had a problem similar to this, so i performed a pmi (programmable module installation) on the ficm to try to trick the ids into programming ficm again and it worked. our ids's are junk and if you even look at that usb port the wrong way it will mess up the vcm and cause all kinds of problems when reprogramming also was your icp sensor leaking oil giving you the codes, or just bad. i hate them 03 and early 04 icp sensors . just a thought on the ficm. i also had one where cust just bought truck from us and brought back in the next day with no power. he called me every name in the book and what it was is he put new air filter in himself and sucked a rag into turbo. hope this helps

 

BLASPHEMY!!!

Garbage equipment....ten grand for JUNK.

I don't hate them...i just hate CHANGING them...

Last 03 I did I changed the ICP when i had the cab/heads off.

 

Yes, the ICP sensor was bad...it had oil in the connection where it connects to the harness. So they relaced that...then they did a check and pulled codes stating that the problem was not MAF (mass air flow sensor) being bad. They told me to take the truck to a different dealership to see if they could "reflash". I took it to another dealership and they ran diag. on the truck and it said the same thing MAF sensor bad. they also said that I have an aftermarket air filter and they want me to change back to stock (problem is...I threw the stock one away).
Well, I have the new dealership changing the MAF sensor ($578) and they think this will solve the problem. I told them to reflash it and they said they would...Lets keep our fingers crossed! This reflash has cost me almost $1,400 in shop work...and I hope this solves the problem...this is ridiculous.

If this doesn't solve the problem, I'll tell them about how you did that PMI thing. Maybe it will work. Im still thinking it is all sorrounding the FICM. We'll see. Thanks for the input guys.

 

If memory serves me correctly, the MAF is only used to calculate EGR flow on a 6.0, so the EGR PID may also be out of spec.


I might just talking out my butt though, it was a long time ago I did my 6.0 training.

 

Just wanted you to know I picked up my truck yesterday evening and it is back to normal!!! What a relief!!! About $1,300.00 later, but it is back to normal. I had the dealer change the MAF and I had them "reflash" the system. Now it is back to normal! They say it was the MAF sensor is what the problem was, but in all honesty...I think it was the reflash. So to conclude...I had to get a ICP sensor, a MAF sensor, and was finally able to have the dealership reflash my truck and it is now back to normal.

**PS- I said back to normal...it doesn't have the buzz like I had after they did the original reflash, nor do I have the louder whistle now that I just had, but I dont care...Im just glad I got my truck back to normal!!!**

I hope this helps anyone out there who may get into this same scenario**

**Also, I want to thank Big Angry Hillbilly...because he has been a GREAT help and has given lots of usefull feedback and troubleshooting** If there was a way to give an award on here, I would do that!!!! Thanks again Big Angry Hillbilly...and if you ever need anything, dont hesitate to ask!

 

Glad to hear you got it back to normal.

 

 

I have heard a lot of bad stories about recals and reflashes on the 6.0 My dad has a 05 6.0 and has been to the shop twice one time for a fuel pump and the other was for the AC. We taped a note on the radio that said absoulutly no reprograming under any circumstances
