Evaporative Emission Control System issue?

After I got my car out of the shop from an inspection that required a new catalytic converter I got two OBD-II codes:

P0441 and P0446

I do notice that after driving for a while you get a faint aroma of gas towards the back after parking and getting out (both sides).

This is a 1999 Toyota Corolla, any help or pointers would be appreciated.

    P0441 Evaporative Emission Control System. Due to an Incorrect Purge Flow.

    P0446 Evaporative Emission Control System. Due to a Vent Control Malfunction.

    Take it to your nearest mechanic and ask if they can take a look at the "Purge valve or Canister", this being related to Error P0441. And as for P0446 ask them to look at the "EVAP Canister"

    Hope i helped :)

    don't think it. bypass to a diverse guy or woman. likely scenerio is you do no longer tighten your gas cap good adequate or the gasket in the cap has long previous undesirable. whether it must be something else in the gas evaporative gadget.

    Loose Gas Cap and Service engine lights on, but gas cap new and tests good, suspect EVAP System.as possible problem
