PO1400 Manifold differential pressure circuit malfunction

Did somebody face this code?
Is the MDP (Manifold differential pressure circuit malfunction).
I get this code for some time and I do not know where is the problem.
What about the pressure into the MDP?Where it must be the right pressure situated?
I assume that is a problem with the wires into my ecu because also my map goes to pin 92 (same with MDP sensor)....
My MAP is working properly and I do not think that is a wiring issue.
Could be that the MAP and MDP into the same pin is the problem?

Could be a vacuum leak?
Could the blow off cause this problem regarding the leak?
