Yes, that's OK.
Does the closed throttle switch "click" ?

UPDATE:
I got a new BOSCH TPS (0 280 120 322) and am now getting the following readings on the switch:
on the Switch Pins 2 & 18
No Throttle - 0.5 OHMS
Throttle - 0.L
on the Switch Pins 3 & 18
Rest/Idle (No Throttle) - 0.L OHMS
3/4 Open and then all the way open - 000.5 OHMS
I believe this is the way it should be now.

John - Yes it clicks however you have to have, in my opinion, EXCELLENT hearing. I had to use a stethoscope in order to be able to hear it click. I also had a conversation with Bosch Tech support, and they told me the newer TPS, not just for Porsche, are much quiter.
Thanks again and will keep posting if I have any other issues.

I can hear the old ones, but as I am pretty deaf in one ear and have bad tinnitus there's no way I'm going to hear a new one :-)
When you mount it on the throttle housing, make sure it clicks correctly as the htrottle plate starts to open, and always clicks as it returns to the rest position, by using the slots in the mounting flanges.
