    More throttle info

    A sudden inspiration this afternoon, stemming somewhat from a
    discussion over on cleanmpg, led to an add-on page to the
    throttle body stuff. This shows where the throttle flap sits
    at various percentages of position as reported by the computer.
    Enjoy. It was a fun little photographic project, for the most part..

    Very nice, but Patrick's butterfly is cleaner than yours :)

    Hmmph. I cleaned it pretty thoroughly maybe TWO YEARS ago, and
    relative to how most cars would be by now, it's pretty pristine.
    I also dropped a teeny bit of lube on the shaft pivots while
    I was in there yesterday. Didn't want to keep the airbox off
    too long, because it's still pollen season up here in a big way..

    Re: More throttle info

    Hi Hobbit,

    Fascinating...

    I assume that the car was IG-ON (not READY) when these readings were taken?

    What instrumentation do you use to determine the throttle opening %s?

    Hi Doug,

    Glad that someone noticed my throttle body avatar; that photo is of the 2001. I'm rotating various Prius photos through the avatar on a monthly cycle.

    Yup, it was IG-ON so the throttle motor wasn't trying to fight
    me, and I just eyeballed the autoenginuity reading until it was
    stable before snapping the pic. The car still threw a code
    afterward, of course, because I had the MAF/IAT connector off
    while the ECU was powered up, but not biggie as it just reset
    later.

    Watch your fingers! That motor is powerful. I've seen one eat a screwdriver and bend the throttle plate. Students!!! :rockon:

    Anyway, I liked the animation also. But to really clean the butterfly, one should unmount the throttle body. It is the only use for 5/16" bolts wrapped with electrical tape. To plug the koolaid tubes, of course.
