Df70 Check Engine alarm

[Dos Caņas]

I know this was discussed before, but I'd like to have this code identified is it 3-2 or 2-3.
It's happening on an engine that hasn't been used for 2 years. Sometimes it clears.

I've found the problem. The vacuum hose from the MAP sensor has broken off before and has had a botch-up repair using some sort of compound glue it in place. Now it has broken off again.
I hope I'm wrong, but think a proper repair would mean replacing the inlet manifold.
The photo shows the end of the hose. I need to replace whatever the circled end of the hose in the diagram connects to.
Can anyone confirm if it is the main manifold or 'hopefully' something smaller.
