Mack cxn 613 throttle cut out

[roth25]

I have a 2006 cxn with an ac460 throwing codes of extended range boost pressure voltage above normal or shorted to high and  variable geometry turbocharger actuator #1 current below normal or open circuit. When I’m pulling and building up boost the throttle completely cuts out once it builds around 40 psi. Curious if anyone has any ideas or similar problems with a solution

Yes.. Has the boost sensor been replaced recently ? 

[roth25]

Yeah I replaced it about a month ago

So... many years ago i chased this issue.  I could drive the truck fine around town at low RPM's.  I would get on the highway and at about 1600 RPM's or 28 PSI of boost, the truck acted like I shut it off.  It would dump boost.  It was the new boost sensor. It was the wrong part number for that VIN. turns out there are a few of them and all of them have a different voltage range on its 5 volt circuit.  The one in my case was 1.5 volts (if I remember correctly) different than the correct sensor. Its been about 17 years ago..  Maybe Heinze can figure out the part number, and Mackpro is great with these sensors and such..
