I'm new to my protege and I'm installing the Throttle Position Sensor (TPS) for the first time. When I turn the sensor over I see a silver disk with two electrical terminals, positioned vertically side by side. The disk and terminals (one piece) can be rotated in a half circle. Do I need to make sure the disk is rotated to a specific orientation before installing and tightening the screws? Please help. Thanks.

 

YESS!! make sure it is turning with the metal piece that opens and closes the throttle body valve and it should be to one side i can't remember which side but make sure it does not over turn or it will break, ive done it before i went through 3 tps sensors before i figured that out.
