    Question 2012 seadoo rxtx fault code p0122

    Going crazy with this guys, wont go over 2000 rpm with a very rough idle cause runs way to rich, have check engine light on with code P0122 which is TPS sensor I changed the tps from another working ski it made no difference, changer ecu no different, changed steering sensors no difference, my warranty is gone im traying not to take it to the dealer without warranty it could be a bite on a leg. Can someone that had this issue help because noone is posting their fix lately

    I "think" after you change the sensor you have to have the TPS reset and codes cleared on BUDS or CanDoo.

    Already changed tps sensor also the ones in the steering I also change the ecu with all those part and still doing the same thing doesn't go over 2000rpm and sound rough with bak fire thru the throttlebody

    If you're on a suspension ski, raise the deck all the way up, reach in and squeeze all connectors together. I've had problems if they were even a hair apart.
