I don't know what car you have, but on my 5000 Turbo there is a small
air hose that runs from the intake manifold directly into the
engine management computer itself.  The pressure sensor is built-in
to the computer.  This is probably not shown in the Bentley wiring
diagram, because the air hose is not eletrical.
