Check fuel cap light & vapor canister
Today while I was driving the "check fuel cap" light came on. The gas cap was on. There are no visible leaks. I did not notice a fuel smell around the gas cap or filler neck, but I did notice a faint fuel smell around the vapor canister.
I'm going to try replacing the gas cap first just to be sure, but I've got a sinking feeling it's something else.
I checked for codes. There are none.
Can the vapor canister be removed with the bed on? My truck has Line-X covering the bed bolts, so it's really only accessible from below.
