Does anyone know where the throttle position sensor is on a 1994 Toyota pick up standard 4 cyl 22r.

Its located on the side of the throttle body The TPS is black plastic with an electrical connector attached to it

I know what it looks like where on the engine is it center under left right?

The throttle body is at the end of the tube coming from the air filter.
