|  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. RE-INSTALLING: 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.  You're DONE! A pic of the "rivet-screw" with a notch cut into it for screwdriver removal.  ***If your TPS is set from the factory, DO NOT ADJUST IT***

| if you dont have a dremel, take the throttle body off, and then use a hack saw to cut the groove. |

| 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.... |

| old thread, but you'd use a multimeter to adjust it; 0.47v closed, 4.53v WOT |

| 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. |

| Just take it off. It's so simple and takes like 5 mins to get it off. |

| FYI the "rivet-screws" are actually "snap off screws"they have a double head and you tighten them till the heads snap off |

| Can anyone update the pictures on this thread? Or present new pictures of the actual screw head and the compatible tool to take them off with. |
