The OBDII reports Code PO455 - EVAP Emission Control System Leak (Large). How can I fix this issue? I don't see the EVAP Emission Control System diagram under the hood.

Hi there,

In most cases the evap vent control valve is the culprit, but it's best to have a smoke test done to find the leak in the system, then do the repair to save some money.
