Hey guys, Juts bought a Gl450. 2007. it has 110k miles on it. Check engine light came on. I checked and gas cap wasn't oem. so i bought an gem one. they didn't change a thing. what else could it be to cause that code?

So i bought the EVAP canister vent valve. I can't figure out where it is located. after i changed this and if it is this, should the check engine light go right off?
