What do I repair/replace for code 446

Question

Trouble codes 440, 441, 446

Answer 1

P0440 EVAP emission control malfunction

P0441 EVAP emission control system incorrect purge flow

P0446 EVAP emission control system vent control

You may not have to replace anything at the air fiter and this happens alot when changing a air airfilter , The airfilter housing there is a EVAP vent hose that attaches to the Purge control this hose tends to get disconnected, If disconnected just reconnect. These three codes always show up in whenever there is a fuel cap not properly installed or fuel cap is not properly sealing, Or the emission hose is disconnected
