Toyota Rav4 P0456 Evap leak when Cold!

Have seen this a few times now on Toyota in particular. I think its because its system might be better at detecting really small leaks then a purge and vent style evap system. So during cold nights when the plastic start to contract a lot its cause that small crack to leak. Either you need to wait until its cold enough to smoke the system or perform a visual inspection like i did with my borescope. Thanks for watching. like comment and subscribe for more.
