Morning all I have a 2007 Mack trident 470 ccrs ea7 keeps throwing code 4-5 turbo actuator I have tested the actuator and there is nothing visually wrong with it and no air leaking out of the diaphram Cannot find any other boost leaks or rubbed through hoses I am thinking it may be the 2 sensors in the intake manifold one at top front one at rear behind computer any help or pointers appreciated note engine photos is not my engine. Just as a guide as I’ve been told there is a few different ones
