[Peugeot-L] 505 Turbo AFM checks

There's one test shown in the N9T/N9TE/N9TEA for checking the AFM:

Connect an ohmmeter between pin 5 and pin 7 of the AFM. Then move the flap door slowly to full open.

It says it should be between 60 and 1000 ohms.

Now, I've done this test on 4 AFM's. You'd think that whatever the value the book was calling for would be a clean sweep from low (full shut), to high (full open). Not the case, on all FOUR that I have. They seem to jump around a lot. As the doors opens, the value rises, but can go up and down, and full open on all isn't the peak value.

(more like, 60(door closed), 100, 300, 150, 500, 800, 200, 900, 400 (full open))

Is this normal, or do I have a bunch of bunk AFM's?

Here's a sample reading:

full shut: 80
peak: 1000
full open: 450

Do any of you have experience with this? Or would any of you be willing to test the AFM's you have? I've been looking around the net to try to educate myself on exactley how these things work, but haven't found anything on super bouncy readings.

thanks!
