Toyota Repair: 98 Toyota Corolla Engine Light on, emission control system, toyota corolla

Question
Dear expert:

2 weeks ago my car engine light turn on, I went to Auto Zone to check on the code. Here is what their computer print out.
Code P0446
"The PCM has determined that a malfunction exists in the electrical circuit for the Vent control in the evaporative emission control system."

Code P0441
"The PCM has determined that the purage flow in the evaporative emission control system is incorrect for the current engine operating condition."

Please tell me where and how it can be fix.

Thanks  

Answer
The most common cause for these codes is that the gas cap was not tight, clear the codes and make sure the gas cap is tight and see if the code returns, if it does look under the hood for any disconnected hoses related to the evap system, if not, take it to a toyota dealer for further diagnosis as there are many other things that can cause these codes.
