Re: code p0440/p0442 help????????
Catalytic converter would set a p0420 code, catalyst efficiency, if the system reads the cat is not doing it's job. Plugged cats cause performance issues, but both are unrelated to the emissions system. The evap system consists of the purge solenoid, vent solenoid, the lines, and a charcoal canister.
