    Fx sho error code 23

    Been reading up and found its my manifold intake sensor . What I cannot find is what is its job ? Does it measures the air / fuel mix or is it more to do with if the engine overheats and what would cause it to fail

    What would cause it to fail and if I rode my ski until my new part came would it cause any damage ? I had to ride it the way it was for around 20mins today to get back home I had full power with no limp mode . I will take a look at the connections before I order new one which will be tomorrow

    Also replacing the sensor would that clear the problem or could it be something else

    I dont know how the ecu operates or its part on the Yamaha platform.....on cars they work with other sensors and ecu uses those readings and adjust fuel.....The Yamaha platform may be pressure mapped and in that case will trip a light if intake temps get bad. try reset and restart ski, if code comes right up its the sensor......if you have to ride it for a while may be a cooling issue

    Check your connections and wires for rubbing
