1982 AFC tests
 

I have a 1982 US Model and I am trying to test the readings from the AFC unit on the intake. From my understanding when the flap is moved within the unit, there should be a variable reading if an ohm meter is attached to the correct contacts on the unit. There are 5 connector pins on the unit and I do not get any sort of variable reading from any of the pins when the flap is moved. I have connected the two leads from my meter in different combinations to all the various pins and do not get the expected readings. Am I doing this wrong or is my AFC messed up? Tested the pins according to the manual and got correct resistance readings as per the manual it makes no mention of a variable reading when the flap is moved. Any ideas?

Maybe EZF pin 6 ye/re (yellow/red), and pin 27 gn/br (green/brown), or pin 7 gn/re (green/red) , and pin 8 gn (green).

Tried that and no change in resistance. Used both a digital and analog meter as well. Do I perhaps need to probe into the connected plug and test for voltage vs. ohms while the car is running? Still not sure of the pins to probe.

Nice 944 web page that describes how to check the AFM

Got this off the other main 928 message board.
