That part number is not in my 2011 manual. So maybe this is a 2013 thing?
However in the parts list I did find this and in fact it's the same thing I was talking about in the above post.
It's the part that goes on the tank that in the service procedures they called it a "Vent Valve".
Here on the parts list they call it a Rollover Valve.
So again it has no electrical connections so it's not a "sensor". It probably just has a ball bearing in it so if you roll over it closes off the vent line.
Again I cannot see this causing much of an issue and if somehow it got stuck closed, nothing would get to the Evap canister.
So again, maybe in 2013 they added something like Part# 709000413??? Or just a new part number for the same part on the 2011?
