Load up MAP BARO EBP in psi it is easier to read and post results KOEO. If at sea-level should be close to 14.6 I believe I'm at 4500ft and read 12.6psi. Also load VGT% IPR% ICPv and desired then drive it.
Watch the MAP and EBP and see if they move. Your VGT at idle should be around the mid 70% while driving see 50's.

 

I am not sure what your position is... In my case I have time and not money, and my truck is a secondary vehicle so if it's down, it's not a big deal.

Given that, here is how I would go about it.

First, inspect wiring for chafing or damage. Common issues are fan wiring and the area where the harness runs between the power steering lines, air filter housing and heater hoses. Your's being a van, it's likely different (no cost, just time)

Then, do point to point wiring tests to insure there is no breaks or shorts.
This means to use a multi-meter on the ohm scale and check from the computer connector (with it and the vgt connector unplugged) to the VGT solenoid (both wires). check for continuity and to ground. There should be almost no resistance end to end, and no continuity to ground. you might also want to do the same for the MAF. (again, no cost, just time)

As others have said, check that map, baro, and ebp are all the same koeo. check for leaks, plugged lines on the Map and ebp. look for soot marks around the up/down pipes. (again, no cost, just time)

Check the MAP hose and hook up a vacuum hand pump to it. watch the the MAP reading with koeo to be sure the numbers make sense. (again, no cost, just time)

If you have IDS you can run a turbo vane test at high idle that should sweep the vanes. (again, no cost if you have IDS, just time)

Assuming all that is intact, I would see if you can move the turbo vanes on the vehicle... this might be easy on a van because of the doghouse. Check out DTR's video on p299/cleaning and 2/3 of the way through he removes the snap ring and uses a screw to push and pull a plate that is attached to the vanes. you might have to remove the VGT solenoid to allow the oil passages to have some room (I rather think not). if you end up having to pull the turbo, clean it anyway and inspect. (no cost, or very low cost if you pull the turbo, mainly time)

This is how I would approach the issue assuming I am having a boost failure. PCM failures are not common outside of other damage (ie harness shorts).

Also, I am writing this from memory so ymmv. also, post your location... there may be a local that can help.

Thanks for the latest posts ,from both of you, really has my wheels spinning.

Yes , I'm definately at sea level .

KOEO MAP = 14.9 psi
BARO = 29.9 inHg
EBP = -0.1 psi

IDLE ICP =.58 psi
IPR = 23.83 %
VGTDC = 85%
BARO = 29.9 inHg
MAP = 14.6 psi
ICP (DES) = .58psi
EBP = .1 psi

Highway speed ICP = 2.38 psi
IPR = 58.59 %
VGTDC = 85%
BARO = 29.9 inHg
MAP = 18.5 psi
ICP (DES) = 2.37psi
EBP = 5.4 psi

So thats what Ive got so far, I'll be up trying to figure out how all these relate to my issues. Thanks for the help!

 

I am betting on a stuck turbo.... your baro, map, icp @koeo look good. Given that even at idle you are seeing 85% vgt I am betting it's not able to move at all.

The only other thing I might recommend is to check for a clogged cat.

Hey Richard,

So you think turbo stuck vs the VGT being stuck?

Roger

 

That's my guess if you checked for leaks and wiring.

Your ICPv at idle is low should be closer to .8v which is round 585psi. Check that ICPv at KOEO should read .21. Try unplugging the ICP sensor and drive it to se if the problem is still present.
Your VGT at 85% is as Darkstar said could very well be a stuck unison ring in the turbo. Make sure the wiring to the solenoid on the front top side of the turbo is plugged in and not chaffed and shorting out. There is a video from DTR that deals with the cleaning of the turbo but don't remember what it's called.
