I got this code on my 2002 buick century, 66795 miles any body had any experience with working this code?

thanks

 

I means your vehicle has a problem with the Evaporation Emission vent system.
There are a few things that will cause this code to set.
A problem with the vent valve itself , electrical problem ie short to ground, short to power,stuck valve, possible PCM problem.
Did anyone just purchase fuel and not put the gas cap back on tight enough?

 

No gas cap problem in fact when i went to loosen it and check the cap it was under a slight vacum. Do you think it is the vent valve solenoid? i took it out and cleaned the dust from it and checked the lines from the engine all the way back to the tank and could not find any thing wrong but i did not have a way to test the solenoid. Unfortunately you cant find that item at any store so it is a dealer item.
