Thanks for the video, just want to make sure I understood correctly..... Which was the solution? change the purge valve?
I have a chevy cruze 2015 with the same codes and I did the following in the purge valve:
1. Remove the connection to the manifold and try to blow air but it was sealed.
2. Suck air through the valve and air was passing, I even tasted the evap gases. Based on this, it shouldn't let air pass through the valve since in normally close.
Are these steps enough to guarantee that the purge valve must be changed?
Thank you so much

For the most part the valves are stay close. When there is voltage applied at the valve you should have air flow. You suck on the direction where I unplugged close the intake. If there is air flow the valve is faulty. Normal state on this is closed.

@@elitemobileautoelectric7782 Awesome, I'll try to confirm this before making the change of the purge valve, appreciate your help.

So did you have to replace the valve

[@elitemobileautoelectric7782]

Yes the purge valve is know on these engine to go out a lot. This valve stayed open full time and wouldn’t close
