failed emission because of P0442. A small leak was detected. on 2001 Toyota Camry

I was told to repair or replace the canister/purge valve. If I were told to replace those parts, should I pay for a general diagnostic then have the part repaired? how much does a repair or replace costs? The light came one once before and I replaced the gas cap. It did not go off but was told by the person at Auto Zone that the gas cap was the problem.
