1994 940 turbo wagon

Took my Idle Air Control valve off to clean it out.  In FAQ's it mentions
that one should get a reading of 20 ohms between inner and outer terminals
and 40 ohms between the outer terminals.

But my IAC only had two terminals.  I had a fellow checked it and he got 7.8
ohms.  Does anybody know if this is correct or what one should get for a
reading?

IAC is Bosch 0 280 140 516

Thank you
