    2004 GPR1300 Code54

    I have an issue with this code coming on once the ski is warmed up. It does not effect the performance one bit. No issues on the low end or top end.

    Ski has a Riva fuel controller and many other mods.

    Im assuming since it doesnt effect any performance that possibly it may be a false code being thrown...any ideas on how to keep this from happening? Any other thoughts, suggestions or ideas?

    Thanks in advance!

    code 54 is stepping motor malfunction. You need a new stepping motor on your throttle bodies. PM WFO he usually has parts in stock.

    Wouldnt a true malfunction cause some sort of noticeable difference in power somewhere? There is absolutely no difference in any rpm range or throttle position.

    If the stepper motor was bad on the throttle bodies...what kind of symptons would be present? Besides for obviously a fault code being thrown.

    Thanks

    low idle, or no idle at all, mean it will shut down.

    So if the fault code is present...but none of these conditions are occuring...then what should I be looking for? What sends this code or what trips this code?

    Thanks
