    Map Sensor pickup

    Hi all,
    got a pipe that has loosened in the engine bay which sends pressure to the MOTRONIC G71 MAP Sensor, can't figure out where it goes, anyone could help ?
    will try a pic ASAP.

    If its the one I'm thinking on, there's a yellow/green ish coloured hard plastic tube about 3mm/ 1/8" diameter on the right hand side of the bulkhead (standing in front of car). That connects the MAP sensor to a rubber pipe then on to the inlet manifold

        The MAP sensor pressure/vacuum hose is connected to a "T" that is connected to both the intake manifold and the Fuel Pressure Regulator. Item 9 in the diagram:

            That is most likely the vacuum check valve for the Automatic climate control vacuum.
