Hi I have a P0455 code Evaporative Emission system leak. I changed the gas cap CODE still there, any ideas of were to look OR what to look for. also get a p1000. Car runs awesome but not sure what to look for anyone out there have any ideas. Need help. 2003 Xtype 2.5 manual shift.

 

Bottle cracked(inside pass. fender), hose broke from tank to bottle.Has there been any work done in thoughs areas, or in general that might have damaged something.You can pull off one of the hoses and do a LOW volume pressure test ( 5 lbs or less) and listen for a leak. There is a smoke test that they do but you need special equipment for that.

Repairs

Mechanics have ( supposedly ) checked and verified that the Canister is OK.
Mechanics have ( supposedly ) removed the Gas Tank and Replaced ( supposedly ) the Solenoid Valve.
Mechanics have ( supposedly ) checked and Cleaned the Check valve on the throat of the gas Tank and "cleaned" the sealing surface. They claimed that it was "sticky" from "gunk" built up on it.

The Check Engine Light is still on, Steady.

I can NOT put gas in the tank without the pump constantly clicking Off. I can only get 1/4, 1/8, 1/10, 1/20 or 1/100 of a Gallon of gas into the tank at a time. It takes me 20 minutes to fill up with 18 gallons of gas.

 

When you fill the car and refit the gas cap.....do you wind it until you get it to click three times?
If the cap is not sealing properly, you can get evap errors.

Second thought.....has the fuel tank been opened recently for a fuel pump repair or sender unit replacement?
If the bit "O" rings haven't seated properly you can get a similar effect.

 

No, Gas Cap is fine. Looks brand new and I click it more than 3 times.
Like I said, a shop "supposedly" dropped the tank. They said it was "fixed". It's not. They ordered a new Fill Tube w/hose - but then found out ( after my expense ) that the "Check Valve" was in the throat of the tank, not the top of the Filler Tube. They claimed to have cleaned "gunk" off of Seating Rim of the Valve. Thanks.

 

Sorry, I had a typo in my post.....I meant the big "O" rings that seal the fuel pump access ports.
I recall that another member (Dell) had evap errors he was chasing and eventually found one of the "O" rings hadn't seated correctly giving him a slight leak and evap errors.
