    Hello,

    I may have a bad throttle positioning sensor <_< Problem is the TPS is not a piece by itself, therefore I have to buy a new throttle body, This will cost about $500 :blink: through Majestic Honda.
    First how can I tell if it is bad or not?
    Second any alternatives?
    Thanks in advance!

    Which throttle body do you have? As far as I know, most Honda TPS's are removable, separate from the throttle body. If you indeed cannot remove the TPS, I highly doubt you'd have to pay $500 for a new throttle body. Shop around for a used one, I'm sure you could find one for $100-200.

    TPS sensor is removeable. It may look riveted in but it is not. If you put a notch in it with a dremel you can unscrew them with a flathead screwdriver.

    Nice write up :D
    Pardon my ignorance, how does the voltage vary from reassemblying the TPS?
    Here is my issue.
    My car runs real rich, ( I had it on a dyno this morning) We think the TPS might be the problem. Any way to tell before I tear it all up?

    So your car is running rich so you are blaming it on your tps? There are many other things that could cause this. What is your setup? ie car, engine, ecu, etc.

    Stock set up, I have not changed the ECU, or minipulated it in any way. I run in the ITC group and it allows very little mods. I have a header on it and the exhaust has a cherry bomb, That is about the extent of it. I will invest in Hondata soon but as per GCR ( general compitition rules) I can not change the ECU unless it is done all internally.

    You may want to look into your O2 sensor too
