SOURCE: Missing flapper valve on an 06 town & country van's gas tank

I doubt if that is the reason your check engine light is on. It is more likely an o2 sensor. However make sure your cap is tight when you add gas and don't leave the engine running while the cap is off. That can trigger the light

Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)

P0455 Mitsubishi Description
This diagnosis detects leaks in the Evaporative Emission System (EVAP) purge line using engine intake manifold vacuum. If pressure does not increase, the Engine Control Module (ECM) will check for leaks in the line between the fuel tank and EVAP canister purge volume control solenoid valve under the following vacuum test condition.
The vacuum cut valve bypass valve is opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP canister vent control valve will then be closed to shut the EVAP purge line off. The EVAP canister purge volume control solenoid valve is opened to depressurize the EVAP purge line using intake manifold vacuum. After this depressurization is implemented, the EVAP canister purge volume control solenoid valve will be closed.

When pumping gas it kicks off and flapper is bent


There is an automatic valve in the filler neck of your fuel tank that is designed to keep gas from jumping back up the filler neck and out the fill fitting. If that valve is bad, you'll have a heck of a time filling the tank, as the nozzle is constantly kicking off and your fill rate is VERY slow. Probably best to take it to a dealer or your trusted mechanic. They might want to replace the flapper at the same time.

Fuel tank flapper valve broke


THe flapper valve will be part of the filler housing and it will require the replacing of that end of the filler tube. Possible get a 2nd hand one fromk the wreckers THe flapper will be on the bottom of the tank and I cannot see any connection to the engine light which would have come on immediately if there was a connection. Run fault codes to determine which sensor./ servo put the light on

Hard to put fuel in tank


Ford Contours have a cheap plastic "flapper valve" at the bottom of the filler neck which supposedly prevents fuel from sloshing back up the neck while fueling. This valve is useless and was never lneeded. When it sticks closed it will make fueling difficult if not impossible. Solution - simply find a heavy cable and push it down the filler neck until it reaches the valve. Give it a heavy rap...sometimes you have to keep doing it over and over until it breaks off the flapper valve. The flapper valve will then float in the tank and will not cause problems. It's a miracle cure that costs nothing. I believe I used a drain snake that I bought at home depot and cut off the large end to do the job. I haven't had a problem with this solution in the past 3 years.

Happy fueling
