I get this code frequently on my Commander. I believe it means you're getting moisture in your sport mode harness somewhere. It will clear itself in a couple of days once things dry out. I've never had any mechanical issues come up like going into limp mode or anything like that but it does suck having to look at the engine light being on especially when far from camp. Someday I'll dig around under my dash and try to waterproof the connections a little better and see if that doesn't help.
