    Seadoo 4-tec "Knock Sensor Adapter"?

    I have a 2004 GTX LTD 185 hp boat. Getting knock sensor out of range fault. When I refer to the shop manual on page #430 it refers to a static test of the "Knock Sensor Adapter" which is supposed to have 19000 - 21000 ohms resistance. I don't have a know sensor adapter on my boat which I bought used. Does anybody know of all 4-tecs have "knock sensor adapters"?

    Thanks,
    Ron

    Should be under the intake manifold. Center of engine.

    I know where the knock sensor is. What I'm trying to determine is if the "knock sensor adapter" (a short cable with resistors in it) between the knock sensor and the plug from the cable going to the ECM is essential to proper knock sensor function.
