Friday I finished replacing the turbo after having it off for cleaning. I took it for a test drive. It cranked and ran okay at idle.but the drive was pretty much just like it was before the turbo cleaning. Scangauge read boost in tenths. Never got over 1.6 and VGT still staying at 85%.
The turbo was not in bad shape when I pulled it, but I cleaned it anyway. When through cleaning you could open and close vanes with one finger. I also spliced in a new solenoid pigtai because the old one came out in pieces
If you have read the 6.0 forum lately I have been struggling with this 2-3 weeks. Again anyone have any idea what I can check or what information I can give you to help diagnose the problem or problems. Included here is the current set of DTC s. I think all the injectors being low is a byproduct of the turbo issues. The fan wires are cut into, the EGR has been deleted and I am running an AirDog 2 in lieu of the HFCM. This could account for the fan, exhaust and fuel codes. Other than that I AM LOST. Thanks for reading. Any help appreciated.

I have an AE with the Ford bundle and my capabilities are for the most part reading DTC s.

Looks like the FICM took a dump or the FICM harness not fulley pluged in

What is your FICM Volts

a bad ficm will cause turbo issues since boost is made with the exhaust anything B4 the exhaust that has an issue will cause turbo problems

 

Hook up your AE and with the truck running go to the "Live Data Grid" tab, find the FICM voltage, check the box and see what the FICM voltage is. Generally all 8 injector circuit low codes is an indicator of a failing FICM.

Other than that get the fan wires fixed.

 

Thanks gentlemen. A fan clutch is ordered. I will check the FICM tomorrow morning and report back.

 

I checked the FICM this morning. I checked the FICM plugs and best I could tell, they were attached. There is one unattached short black wire coming out of the harness at the back of the left(driver side) valve cover. I tried to load a picture and will keep trying.

Following are the AE numbers.

KOEO KOER
11.5 13-13.5 FICM vehicle power
47.5-48 44-48 (mostly 45) " main power
11.5 13-13.5 " logic power

VGT still at 85% and very little boost.
Thanks for any help!!!

 

Oh that little black wire with the loop end needs to go to the rear intake manafold bolt there is a nut that holds it on
It is the FICM Ground wire fix that B4 proceding

Fix the ground wire then check the numbers again especialy after a cold soak

 

The FICM main voltage as low as 44 is below spec, but not very much. It could have caused the injector circuit low codes and indicates that the FICM will probably need repaired or replaced soon.

I don't think it explains your boost problems, though. Just out of curiosity, can you drive the vehicle with the AE connected and watch the Boost PID? It might be called Manifold Gauge Pressure. I wonder if the Scangauge is reading it correctly.

It would also be worth inspecting the MAP sensor, wiring and the hose going to the intake manifold to make sure it all looks right.

 

Connected the short black wire to the valve cover bolt. I cleared codes last session with the AE. The codes were back for the fuel pump, fan and exhaust. Other than that I had P0299 underboost. I checked the live data meter and all of those were close to identical to the first ones. I drove it with the AE connected reading the manifold gauge pressure and it agreed with the SG2. VGT remained at 85%. Checked the MAP sensor and connections and everything seemed in order. MAF 14.39 up to 15.4. I think that pretty much covers it. Thanks!!

 

Get the ground wire put back on the past stud on the intake and retest. I would bet that your FICM is bad. But maybe just needs the ground hooked up. As far as 44 volts I think I read somewhere that that's the lowest reading that AE will display. So even if it was only 20v it would show it as 44.

Edit.....never mind you posted at the same time.

 

I'm sure you need to have your FICM fixed or replaced.

The MAP is odd. With the engine off, MAP should read the same as BARO. Unless you're at a higher altitude, your MAP is nearly lower than barometric pressure. I don't see where you live, so maybe it's nothing, but compare the MAP and BARO pid with the engine off. And tell us what they are and what altitude you live at.

 

I just recently had my FICM repaired. I had many of the same codes you have. Ed at ficmrepair.com took good care of me.

 

I hope everyone had a great Thanksgiving. When I wasn't busy eating I was working on my X. I replaced the FICM with a working used unit. All of the voltage readings were now in spec. That however did not improve the VGT readings or the lack of boost. I replaced the VGT solenoid with no improvement.Just to make sure, I unwrapped and rechecked the new pigtail going to the VGT. Not the problem. I found a used 6.0 turbo from a wreck not far from home. WTH I've gone this far. ? I replaced the turbo. As soon as I fired it up the VGT reading was moving from low 70s to 85. First road test I blew a CAC tube at about 8psi of boost. Repaired the leak and drove it again. About 10 minutes into the drive at 18 psi boost I blew another CAC tube. So I eased back home and tomorrow morning when the truck has cooled I will remove the problem boot and clean and spray it. BTW this is the lower driver side boot that has not been off since it was cleaned and sprayed some time back. I think we have solved the problem "du jour".. Thanks for everyone's input and assistance.
