Grande Punto 1.4 16v 95HP MAP sensor

I have question about MAP sensor Bosch 0261230052 that is mounted on plastic plate holding intake manifold to head. There are just hole, no hose or something else. Is that right or something missing there? What is Bosch 0261230052 function?

And what it measures? I though that it must work in closed volume like this, mounted directly to intake manifold.

ECUs need to know both manifold pressure and ambient pressure in order to correctly compensate for altitude/temp..etc.

Some ECUs have the ambient pressure sensor built into them. Not sure about yours, but Bernie is probably right.
