I metered the Throttle pot on my 89 900 and found similar results but just before fully shut you should here a microswitch actuating and that was the only thing that showed up on the meter as either open circuit or making a proper contact.I was told that it was some kind of digital pot and this was right. If this is true I cannot say!
