There is a large misconception that Honda and Acura Throttle Position Sensors are "Riveted" in. This is false. Those "rivets" are actually screws with no head on them. You can either use a flat headed screwdriver and hammer to remove them, or you can cut a slot into them with a dremmel and unscrew them with a flathead screwdriver.
This is the "rivet-screw" that we are addressing.
THE HAMMER/SCREWDRIVER METHOD:
Get a good flat-headed screw driver that has a good edge on it. You need the good edge to dig into the screw material. Place the screwdriver at an angle in the position shown:
Tap the end of the screw driver with a hammer. The screw will rotate counter clockwise and loosen. You should be able to finish unscrewing it with the pad of your thumb. This way is kind of a pain.
THE DREMMEL METHOD:
Cut a slot into the "rivet-screw" Use a steady hand and cut carefully. Cut deep enough into the screw so that you can get a standard screwdriver blade into the slot.
Unscrew the critter.
You don't want to re-use those crappy "rivet-screws". Go to the hardware/parts store and match the threads to a new, stainless metric bolt of the same size and length. If you have a Fast Idle Thermo Valve laying around, you can rob the screws from the cover plate, which is what I did.
Make sure the Plastic tab "A" fits into the slot "B" upon re-installation.
When you initially install the TPS (Throttle Position Sensor) It will be way-off.
Just turn it counter-clockwise untill the bolt holes line up.
Screw the bolts on finger-tight, plug it in, and whip out the multi-meter!
Start the car. With it Idling, Measure the voltage between the red and green wires. Adjust untill the voltage reads .45V at idle. Tighten those screws/bolts down! Re-check the voltage.

Now, just forsay, you've installed a *brand new* throttle body, your going to have to adjust the idle too. I've found the tps alignment affects that. So how do i go about lining both up, other than a few hours of testing? I'm guessing there's a method but i'ma n00b.
go figure but my TPS had torx screws from the start. JDM SiR II....

My JDM D15B VTEC didn't have removable TPS bolt. It depends on what motor you have I believe because the TB I swapped and am using right now has removable screws(Torx head also) and is not JDM.

thread's 5 years old, so chances of it being updated are pretty slim.
there are however other writeups for how to do this
