I just looked up the parts diagram, Yamaha calls that part a "stepping motor". I have no idea what that does? Based on the diagram, the o-ring is in the correct spot. That part is $112 USD. If it were me, I'd clean up both that part & the hole it goes in. It looks pretty dirty to me? After that, coat the part/o-ring with grease to lubricate/seal the o-ring. If that doesn't make the error code go away, it may need to be replaced. Like I said earlier, I have no idea what a "stepping motor" is, or if that would cause the idling problems/code 14????

Based on the "Code 14", my interpretation is that a "hose" is kinked, or plugged.... That part in your picture doesn't like a hose? It looks like an electrical component. Being that Yamaha calls it a "stepping motor" leads me to believe this part is most likely NOT the source of your problem....
