What is the port under the inlet?

[Mouse]

On the back of the 1200 engine, there are two ports, one underneath each inlet port. The one of the left has a hose leading from it to somewhere under the airbox (?), the one on the right has some sort of sensor attached.

Can anyone tell me what these are? Also, are they simply blanked off on the 1150 engine? (I've seen "wally flaps" attached to these points on 1150s).

Thanks.

The one on the left is part of the engine breather - the hose goes into the airbox.
