It is mounted on the side of the throttle body next to the throttle position sensor.
If you are replacing it you will want to measure how far out the pintle is. It should be no farther than 28 mm. I normally compress them a bit and let the system reset the distance after the passages are cleaned.

On top, in this case. My TPS is on the bottom, so that was it.
