I have a 2004 Alero and I just figured out today and replaced my throttle positon 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. http://en.wikipedia.org/wiki/Throttle_position_sensor
The 2000 GMC throttle position sensor can be found on top of the engine. The throttle position sensor will be near the injector fuel pump.
The throttle position sensor on a 2000 Cavalier 2.4 is on the throttle body. It is mounted on the right side of the body.
The throttle position sensor is mounted to the throttle body on the opposite side of the throttle cables and is faceing the rear of the engine compartment.
The TPS (throttle position sensor) would be found on the throttle body on the opposite side of the throttle cable.
the tps or throttle position sensor is located on the throttle body on the opposite side of the throttle linkage
I believe it is on the side of the throttle body
It is on the throttle plate right across from the throttle cable.
It is located on the throttle body, opposite of where the throttle cables hook on.
TPC= throttle position sensor.
It is on the throttle body, opposite of where the cables hook on.
It's a part of the throttle body assembly.
It is on the opposite side of the throttle body from the throttle cable attachment.
