I did replace the gas cap before the check engine light came on not sure if gas cap could be faulty after a year which would cause 3 codes to come up. Anyone know how to check or have a diagram of where these vapor lines are? Gas tank reads E.
Getting codes PO455,461 and 463 can I get to gas tank to check lines from trunk? on 2006 Pontiac G6

I REPLACED THE CAP WITH AN AFTERMARKET CAP. WILL CHECK OUT THE WEB SITE YOU RECOMMENDED. GAS GAUGE DOESN'T WORK AT ALL I SHOWS THE TANK TO BE EMPTY.
