Ferrari Mailing List: Re: How does sensor plate work......

First, you need to look VERY closely at the pictures and your unit.  They are NOT the same.  Figure 15.1.4 is a traditional setup as used on many VWs.  The pivot point for the air flow arm is behind the point at which the arm contacts the plunger on the distributor.  The variation on our cars has the contact point for the plunger behind the pivot point for the arm… so the pictured version the air flows UP.  On ours, the air flows DOWN.  Hope this helps.

 

I had mine apart in the last year and sent all the critical stuff to Larry Fletcher for rebuilds.  Pictures here:  http://www.flickr.com/photos/moseley_ferrari/sets/72157622414223889/

....shows how the sensor plate (56 mm by the way) works. But there is something I don't understand even after reading the explanations.

Is the air coming through the air filter supposed to push down on the plate, thus allowing more air as I go faster ? If that is so, then I don't understand the directions of the green arrows on the picture.

I need a SENSOR PLATE FOR DUMMIES type of explanation.
