Does anyone know where this valve is located on and 07 s80.

 

do you mean the purge control valve?

 

I guess that what i,m looking for, its throwing a code of p4241 evaporative emission system vent valve stuck open

 

Did you check the gas cap then clear the code to see if it returns?

 

yes cleared code and a few miles later check engine light came back

 

so the things to check out are 1) is there a vaccuum leak (the purge valve controls the canister via a vaccuum line that runs from the front to the cannister near the rear wheel) 2) is the purge valve working? (you'd need to check if there's additional codes for the purge valve - more common are the small evap leak vs large evap leak fault codes) 3) fault within the cannister

I'd start by checking out the parts diagrams on a dealer web store like tascaparts.com or others then inspect the vaccuum line and other components

 

Thks, that give me a start as where to go looking..
