what is the recall I should ask them to do for the symptom below? on 2009 Toyota Corolla

my dealer want 800 to swapp the Charcoal Canister on my 2009 Corolla CE. Check Engine light was coming on solid consistently for a week or 10 days, now it is staying off. They also dinged me 100 to tell me the error.
