I think your talking about the fuel-consumption sensor on the air-flow 
meter right? Well in that case, there's no spec in the Bentley for 
resistance, but yer actually s'posed to measure voltage. Pin1 is 5V and 
pin3 is gnd. Pin2 is the output voltage. All the sensor is a simple 
potentiometer setup as a voltage divider. To test you can apply 5V on pin1 
and 3 and monitor pin2. At rest it should be 0V. At idle it should be 
0.2-0.5V. There's a special gadget [VW1348/1] that fits over the air-flow 
plate and holds it w/ a magnet to several set positions like idle and WOT 
[4.0-4.5V]. I've never seen one of those tools and it's prolly very 
expensive unless you know someone. I'm sure a good estimate will work just 
as well, though as the spec range is wide.

The Bentley says you only need to measure one distance. For manual 
tranny's, it's from the rearmost subframe bushings to a casting in the 
middle of the tranny w/ a dime-sized hole in it. The distance is 29.4mm.
For A/T, it's from the rearmost subframe bushings to the first cast fin on 
the tranny under the driveshafts. The distance is 127.4mm. Hope this helps.
