Paccar mx13 losing boost

Were you able to resolve the issue? I have a '16 MX 13 with a similar issue. Runs great but builds manifold pressure when under a load to 40 & loses all power. I let off the accelerator, the RPM's drop, the manifold pressure drops, & I have power again. As soon as it hits 38-40 the power drops. Hard to climb hills like this!

 

Did you figure this out as im having the same issue!! Thanks

 

Did you leave it unplugged or did you replace with new sensor? Mine what it does in the mornings and if I stop and idle my boost goes all the way to 40 psi even if im not loaded it does that for 30 minutes then it drops off and motor and boost running smoothly??

 

Do any of you know where to get diagrams for the sensor locations on an mx13 epa13 paccar please?

What did you figure out from this situation my truck started doing exact same thing for the last five days. I cleaned all the tubes with mechanics wire replaced the intercool temp sensor on the intake elbow it had no resistance. The mechanic that put the tune in 5 years ago thinks my back pressure could be related to a plugged crankcase module cause I’m getting blow by. And advice would be greatly appreciated

 

Replace boost sensor, or @ least pull it out & clean it, gets full of soot, & will debate motor...
