Welcome!
That code means your gas tank isn't airtight like it's supposed to be. Most common reason for it is a loose gas cap. Check that first since it's easy to check. Less common, but other things that can set off that code... - bad gasket on the gas cap - several vacuum hoses attached to the fuel tank, including vents alongside the fill pipe - leak at the flange plate bolted to the gas tank (fuel pump mounting) - leak (crack) in the actual fuel tank itself - problem with the fuel tank pressure sensor I'll move this to General Tech, since thats a better place for it. |
If you don't tighten your gas cap to at least 3 clicks, the CEL will come on after a while. Make sure the gas cap is tightened to at least 3 clicks, then reset the ECU. if the CEL comes back on, you got a problem - likely somewhere JimBlake suggested above.
