EVAP Emission Control System Leak
 
I've been getting the following codes:

P0456 = EVAP Emission Control System Leak Very Small
P0442 = EVAP Emission Control System Leak Small
P0455 = EVAP Emission Control System Leak Large

It doesn't set the Check Engine Light, I just get the codes. Does anybody have any suggestions as to where the leak is?

that can happen from a loose, or bad gas cap. i'd replace the cap and have idiot zone clear the code. its the cheapest easiest place to start.

if thats not it, there's lots of parts on the evap system that can be difficult to diagnose.
