    I've had this check engine light on for a while now and I have had the code ran multiple times. It says is a large or gross evap leak. I've done some research and talked to some people and we believe it has something to do with the Fuel Vapor Pressure Sensor. I was wondering if anyone knew where this would be located on a 2007 grand prix gxp. Also if anyone has any other suggestions as to what may be causing this light let me know!

    I get an evap code on my 07 GP at least once every two weeks... I changed the gas cap and then it came on a couple weeks later then I went back to the old one and etc.... it says its a small evap leak? GP runs awesome so maybe its a hose? or is there an evap canister?
