I have been chasing a few different codes down and just noticed the rollover cap in the filler neck is missing. Could that cause a evap code? Specifically related to the gas cap, 0455,0456,0457?
I have a 2015 Ram 1500, 87,000 miles with all three of these codes. I replaced the gas cap, ESIM and purge canister already. Dealership says I need a new gas tank and is asking right at $4,000. Has anyone else needed to go to that extreme to fix these codes?
