The sensor on top is the manifold-air pressure (MAP) sensor, #11.

The throttle-position sensor (TPS) is on the throttle shaft opposite the cable drum. It's not labeled as a separate part.



If it REALLY is the TPS you need, it's held on by screws that are made to look like rivets. Use a dremel to cut a slot for a screwdriver. Find a junkyard donor & swap the sensors if the actual throttle body doesn't match.
