Up for sale is a BOSCH Throttle position switch. Good used condition.  I did the Saab Bentley manual checks, and this unit checks out functional.  0 280 120 302  Fits a variaty of cars, Saab, BMW, etc.  In Saab applications, this works with 1985-1993 900-turbo cars, as well as many pre 1993 9000 cars, and non turbo 900's from 1988-1990.  Probably even more.  Check your original part number to be sure of fitment!  BARGAIN ALERT for a good functional TPS.

Works fine and comes with a 30 day warranty.   You can still buy these new, but at a cost of nearly $150 they are rather unaffordable.  Thanks for looking and good luck!
