    It's on the throttle body I believe it is the bottom one. It's not hard to remove it all you do is unscrew the screws attached to it and it comes right off.

    The TPS is usually located @ the opposite end of the throttle/butterfly shaft.. On one side you have your throttle linkages and on the other end the TPS.. It usually has a couple or so screws holding it in and has a round plug and connector.. Should look somewhat like the gray (top) sensor in this custom TB pic..

    I would make sure that it's plugged in correctly first before you buy another one. I also heard that the code can be thrown if the sensor is dirty or the throttle body is, so you might try cleaning them with tb cleaner. I don't know how true that is but it couldn't hurt.

    For all the more a TPS costs I would just replace it..

    I also would'nt unplug it while it's running..

    make sure you clean the throttle body. Sometimes carbon build up causes issues too.

    I agree, electrical components go bad after sometime. If it was a $200 part, I might have a different POV.
