You probably have a Leak Detection Pump, so make sure that large plastic tube that goes from the LDP to the evap canister is not chafed.

 

There's another area you may want to check if you have a mind to. There's a Fuel Filler Vent Hose that goes from the fuel filler tube to the fuel tank, that runs along the side of the fuel filler hose.

You have to remove the shield that covers these hoses to get at them. Check the vent hose for deterioration and positive connection to the fuel filler tube.

 

Thanks for all the replies. While check accordingly
