Hi Im David and thanks for visiting the site. chance are a plastic evap line got damaged and unfortunately the only way to find the leak if it not visible is to have a smoke test done on the evap system.
do you still need assistance?
ok bud thanks
yes, do that
ok. keep me posted
Missing Fuel cap - Incorrect fuel filler cap used - Fuel filler cap remains open or fails to close - Foreign matter caught in fuel filler cap - EVAP purge control solenoid - EVAP canister - Fuel tank pressure sensorTroubleshooting DTC P1456 (EVAP system leakage [fuel tank system]) Pinch off all the hoses between the fuel filler neck and the fuel tank, and retest. If the leak stops, replace the fuel fill cap first. If youve still got the leak after replacing the fuel fill cap, then replace the fuel filler pipe. Theres an O-ring between the plastic and threaded part of the filler neck that may be leaking.
unfortunately yes. chances are anyways, the problem is going to be on top of the tank
ok. allow me a few moment to get you those instructions. thanks.
i cant find any instruction on removing the tank. let me keep looking.
sure, let me work on getting a diagram of the top of the tank to point out the vent hose and pressure hose for you.
ok. up under the vehicle, on the side that the filler tube is there is a vent tube. its metal but turns into a rubber hose. thats what needs to be pinched off. ive circled the areas where the rubber hoses go.
