I have a 2007 Aspen 5.7Liter. I got the code P0440 and the "GASCAP" signal. I already got a new gas cap from the dealer and I changed out the ESIM switch by the charcoal canister and I am still getting the same codes after having a buddy erase the codes with his scanner. What? and Where? should I look for next. Does anyone have a diagram or picture of where the vapor canister is located or where I should be looking for maybe a cracked hose as many people have suggested.


Thanks in advance!!!
