Q: charcoal canister replacement? on 2004 Toyota Camry

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
My engine light came on and the "diagnosis" was to replace the charcoal canister, for a price of $548 plus tax. I cannot find that term on this website. Any thoughts as to what I need?
