you are rotating the whole sensor, just loosen the two screws holding it to the throttle body and it will rotate somewhat smoothley by hand. you want to stick a pin or needle through the middle wire of the tps then hook your meter up to it and a ground source. for connecting the meter I reccomend the wire with alligator clips on both ends as they leave your hands free to hold the meter while rotating the tps.
hope this helps let me know if i need to clarify parts of it
