Question about 2004 Pontiac Grand Prix
Hello! You will need to first make sure that you have a "tamper proof" Torx T20 bit/driver. These types of bits look like a normal Torx bit, but have a hole in the center (example pictured)
The TPS is located on the side of the throttle body (indicated below), and there are 2 Torx head screws holding it in place.
You need to disconnect the connector from the TPS first, by lifting up on the tab (gently) and pulling the connector away from the sensor. Once you have done that, you can remove the screws and then the sensor itself. The TP sensors on these cars do not require adjustment, so there is no need to mark the location as on earlier vehicles. You can now position your new TP sensor and replace the Torx screws and fasten them down snugly - but too tight as you may crack the plastic tabs. Reattach the sensor connector until it snaps into place, and you're all done.
Hope this helps and good luck!

Normally attached at opposite end of throttle linkage. Remove your air cleaner intake hose at throttle body, and observe throttle plate that opens & closes as you press accelerator, it will be at the end of that, on outside of housing.

Look where your throttle cables etc are attached at throttle body, it should be at opposite end of the shaft that operates throttle plate in front of throttle body opening. Usually held on with Torx screws

The throttle actuator motor
The throttle position (TP) sensor 1 and 2
The throttle body functions are similar to a conventional throttle body with the following exceptions:
An electric motor opens and closes the throttle valve.
The throttle blade is spring loaded in both directions and the default position is slightly open.
There are 2 individual TP sensors within the throttle body assembly.
Oh yea it has two TPS - throttle position sensors ! An you have to replace the whole assembly !
