You are correct about the code and description but for Camry, this code does not apply. Can you please reconfirm it?
For the gas cap, it usually would show as P0442.
For Camry EVAP system codes are P0440, P0441, P0442, P0446, P0450 and P0451.

Sorry, I had the code re-read. It is actually P0446

Here is a description of the possible causes and it is not caused by the gas cap.
Most likely problem would be the VSV valve located are rear near to fuel tank. however it could be any of the valve suystems and the diagnostics are rather extensive. Would you like to do the diagnostics your self?
DTC P0446: EVAP VENT CONTROL CIRCUIT.

Yes, I would like to run the diagnostics myself if possible.
