Hi,

I have a 2004 Alero ( similar procedure in your model as well ) and I just figured out today and replaced my throttle position sensor. I'm not sure what the black plastic "box" is called that is above the throttle assembly...but I had to remove that to get to the throttle position sensor underneath. If you can locate the two wires that control the throttle assembly...then the throttle position sensor is on the other side of the throttle assembly. I had to remove the large tube that went from the air filter to the black plastic "box" above the throttle assembly. Also disconnected anything else connected to that black plastic "box". Then pulled that "box" up and right there on the left side of the throttle assembly was the throttle assembly sensor. Here is a web page with a picture that helped me figure out where it was :-
