Anschluß Saugrohrdrucksensor Thema 8.32

[hjs2600]

Hallo,

als ich die Domstrebe in meinem 8.32 (Serie 2 mit G-Kat) montiert habe, ist mir aufgefallen, das an dem Saugrohrdruckfühler (BOSCH 0 280 101 003) kein Schlauch angeschlossen war, sondern nur die Elektrik. Einen losen Schlauch habe ich aber auch nicht in dem Bereich rund um den rechten Stoßdämpferdom gesehen.

Würde bitte mal einer der anderen 8.32-Eigner nachsehen, wo der Schlauch vom Saugrohrdrucksensor an die Ansaugbrücke angeschlossen ist und mir vielleicht sogar Fotos davon zukommen lassen - Danke im Voraus,

Sorry for answering in English, but this is an altitude sensor instead of an Manifold Absolute Pressure sensor. It measures the altitude, sends a proportional signal to the ECU and the ECU sends a signal to the Electro hydraulic actuator (attached to the fuel distributer) which regulates electically the control pressure of the lower chambers in the fuel distributer and so the amount of fuel injected. This way the injection system is able to compensate for different altitudes
As you'll understand there is no (and no need for) hoses connected to this sensor.

Thank you for your answer!

If my memory serves me well, there are 3 small diameter hoses attached to the intake manifold. One sits on top of the black round steel box for the crankcase ventilation, just behind the distributer cap.
There is another one (originally green hose) that is attached to the Microplex ignition ECU (in the engine compartment behind the fire wall) to measure the vaccuum in the intake manifold to advance ignition timing.
There is a third one connected to the EGR (exhaust gas recirculation) elektrovalve. This elektrovalve regulates that at a certain temperature and rpm the exhaust gasses are being directed back into the intake to minimize toxic exhaust gasses. It happens quite often that people disconnect the EGR system. Doing this by just disconnecting this hose will, in contrast to what a lot of people think, not cut exhaust gasses from recirculating but force them to circulate all the time.

Attached a picture from the components or the hose leading towards the components.
