    THROTTLE BODY Failure

    Who out there has had this

    6S5-13750-00-00 THROTTLE BODY ASSY

    fail. I have 2.6 volts when closed on TPS 2.

    Has anyone fixed theirs or is it not worth the risk.

    Will be removing from the ski tomorrow.

    Cheers

    Daniel

    There is nothing to fix on the TB. My SHO killed an Ecu, TB, and a harness all in one day...thank Jesus for warranty.

    My truck killed 2 throttle bodies in a week. Turned ouy to be a wire harness issue. You might want to check through your harness just to be safe.

    well, I've seen the butterfly stop opening because the needle bearing around the throttle body's main shaft seize and stop working! usually i think its because we ride in salt water and its always ingesting salt air through the supercharger, it can be fixed if someone has the expertize!!
    hope this helps you!
    pm me if you need additional info on how I fixed it before!

    Update on this

    the 2.6-2.8 volts on TPS2 is normal. Comparied it to a mates ski. So after worrying about this problem for a few day. This is my view on how it works.

    TPS1 has a range from about 0.8-4.8volts.
    TPS2 has a range from about 2.7-4.8 volts.

    The ECU only compares the 2 above part throttle or at about 2.7 volts. I don't recall at what TB angle. TPS2 voltage does not start to increase until part throttle. I made the assumption that they are compared the whole throttle range. The service Manual does not give you voltage values to work with for some reason. It does for the APS but not the TPS.

    Anyway that's my take. I could be wrong.

    I've had the fault twice and I found once corrosion built up on area where plate moves. This time the mechanical part was locked up......I soaked it in Seadoo XPS spray lube. I can tell you you don't want to force it with your fingers much.....plastic gears in it I believe

    Yeah I did open it for inspection. All clean. Your right, plastic gears. Not sure why the ECU through that code on me twice. It kind of sent me in the wrong direction.

    Yep that's the acceleration position switch values. Not the TPS values.

    The gears will strip super easy.....if it stays bound up and trys to move it will just damage drive gear....I was told not to work it to much by hand but I did break it free gently
