Throttle Position Sensor, aka TPS. Normally, there's a bent metal bracket which mounts this in position that the plunger presses against a cam. As the throttle is increased, the cam pushing on the plunger, telling the ECU where the throttle is expected to be.

the TPS basically runs the vacuum advance solenoids, shutter and air control valves, so if you don't have those, then you don't need the TPS.
