Engine code P0497

Hello,

The code:
P0497: EVAP System Low Purge Flow

This code can get trigged by a faulty EVAP purge valve. If the EVAP system is not releasing excess pressure as its designed to it will produce a trouble code.
This can be as simple as replacing the purge valve. But it can also be restriction in the tubing or other factors that impacting the purge for the valve.

I have attached the diagnostics procedure for this code. Follow those step by step and that will narrow down the possible causes and will help you find the exact reason.
