Code p0442 & p0445

[jesse121pm]

I have a code for p0442 and p0445 I replaced my gas cap multiple times and it still will not go away. Does anyone know what else I should do it says there is a small leak and a large leak. Thanks

Without a scan tool it's really hard to diagnose this without throwing parts at it. The most common thing would be a leaking or stuck open evap vent valve.

^^^^ This. Good info. Also check all your evap lines as some of them are plastic and can crack or break and cause a leak.
