Yes, the engine will work without the throttle switches. Only when they
are stuck closed or the wiring swapped with the warm up or auxiliary air
regulator is there a drivability problem. The functions missing without
are the injector cut off when the engine is over run with the throttle
closed and full throttle enrichment.

Subject: is it possible to not have a TPS?

I have been having some issues with my '85 vanagon and someone
sudgested adjusting and checking the Throttle Possition Sensor. I
checked the bently and found that the TPS is infact different on an
'85....but i sware there is no TPS at all on my engine! I'll get some
pictures tommorow, but is it even remotely possible that the engine
would still work without one? I dont even have wiring for it. But, i
do have a vaccuum port at the front of the throttle body that has a 1
inch hose in it and a screw capping that off. I'm curious as to whats
really supposed to be there.
