I lost all reading on the Edge for Vane position % today and it will blow black after 6th gear and I try to get on it. From a stand still it pull and reads boost I caught up to 18 PSI. I popped the tow haul button on while I was coming to a stop and the truck turbo braked so I assume the vanes are fine ( not stuck ) and I have a bad sensor. Sound right on the assumption? Code reads 2563 and 2564 after clearing the codes only the 3564 comes back every time.
