Code P0456

I need some help with this code guys. The manual says this is an "evap emissions control system small leak". Where is the best place to start checking for this leak? Anyone experience this before? Thanks for the help.

Mike, first check the gas cap for a good seal. Maybe the O-ring is broken?

The second most likely cause of this code is the evap purge solenoid located above the spare tire. They are prone to corrode.
