2006 International 4300 dt466 running rough and dying intermittently

Well. New symptoms.
If you disconnect the ICP sensor it runs and doesn't die. It has no power but it runs fine. I'm presuming it goes into some kind of limp mode.

I drove with the ICP unplugged for about 400 miles and it never died or stumbled. I also go no more voltage codes. I'm wondering if the UVCH or sensor are shorting B+ reference to B- reference and shutting the truck down.

Is that something anyone has had happen or heard of?

 

Oil wicking through the harness ICP sensor faults ICP sensor is a failure item.
Runs with it disconnected. Sure sounds like an ICP sensor problem.

 

Bingo. Put a sensor and UVCH and it has not died is 2200 miles. VGT is dying though. Does anyone have the software to uprate an engine? I was going to tear the box off and make it a service rig. It will be towing so a few more ponies and a rebuild would be helpful!
