    Default TPS testing 1992 mercury EFI XRI 200

    Hi, On a 1992 mercury 200 xri EFI. how can I test and verify the Throttle position sensor is bad? the part is 500 bucks and I want to make certain its bad.

    per the book i took the blue wire and Tan wire and moved the sensor nothing happen, however the Blue and the Orange wires together worked as the book described where ohms moved from 9-11.

    anyone have any experience with this that can help?
