    umm its right on ur throttle body. Its the black plastic shit that is straight across ur throttle linkage. It has a 3 wire pin wihte connector going to it.

    To better explain it. u see where ur throttle cable connects? well straight ahead on the back is a black thing?? its ur TPS sensor.

    which bolt are talking about?? I didnt have 2 reset my throttle cable!!! I just poped it off the old one and put it on the new one!!! It seems like something is sticking BC i moved some vacumm lines around and now its fine except for this high pitch like sqeal that happens when i push the throttle 1/2 way down!! Everyone think i have a turbo!!!!

    The IACV is bolted onto the front of the bypass valve body (the funky aluminum piece that has PGMFI printed on it). It has an electrical connector and two small coolant hoses attached to it. If you replace it I would recommend two small worm drive clamps to replace the spring clamps bacause putting the old hoses on new hose nipples almost always ends up with slight leaks.

    Anyway, I do think it sucks that Honda chose not to use a throttle position sensor that attaches to the throttle body with screws or bolts.

    Didnt you have to remove the throttle cable to swap TB'S??? when i removed my TB i had to loosen the cable to remove it from the old TB and when i re-installed the cable i tigtened it to much, thats why it accelerated alot on start up. I changed the TB cause i got a code that said something was wrong with my sensor. When i checked, the sensor had some how snapped of and one piece was stuck in the connector. I switched TB'S and no more Engine Light on

    If it does that in between shifts or idling, then most likely is the egr valve.
