ODB code of P0446?

My check engine light came on today on my 2001 V6 Camry and produced a code of P0446 (Evaporative Emission Control System Vent Control Circuit Malfunction)
Can anyone advise as how to further diagnose this issue and what repairs may be necessary?
Thanks
Fred

Evaporation system vent control system malfunction.

The vapor emission system has a leak in the hoses, cracked charcoal canister, defective VSV system, pressure sensor, fuel tank overflow check valve.

A place to start is to check the systems vacuum hoses for leaks and damage.

For more details download the appropriate section for the service manual at the link below.
