Anyone with an original/genuine 037906457D ISV care to unplug the harness connector and measure the ohms between the ISV's two terminals?

If I understand correctly, this is the original ISV for many of the following vehicles:
84-93 Rabbit Convertible/Golf Cabrio
89-95 Corrado
88-92 Golf
87-92 Jetta
91-93 Passat syncro

I'm trying to find out if this characteristic is different from other ISVs of its vintage that appear similar, but sold under different model numbers. Thanks for any help!

Had a chance to measure a used one recently. Resistance was 4.2Ω

This particular valve also allowed a minor amount of air pass-through when unplugged (ie, not completely sealed). Uncertain if that is spec or if it was just a bit worn out.

YMMV.
