Throttle position sensor not working

Why won't my IDL-E2 TPS Terminals register ohms when rotated by throttle shaft but deflects ohms when rotated by hand? I loosened the mounting screws on my TPS & it won't regiser ohms when rotated all the way back & forth. I removed it from the throttle body & it the deflects ohms when turning internal butterfly spindle by hand. Why won't it just get within the correct range w/mounts loose & rotating Clckws/Crntrclkws?

Do you
