    You need to do a thorough inspection of the Evaporative System. A code only really tells you what part of the system is malfunctioning, not the part. If you have incorrect purge flow, it could be many things. All this says is that the Purge flow is incorrect.
    I do Emissions work in California and Evap codes are really tough, some times. The State of CA will give us 2.3 hours to Diagnose an Evap code.
