Check your fuel cap. You may have to buy a new one in some cases because the seal on the old one has gone bad. Before you buy a new one though.... Tighten the old one and try to erase the code is it doesn't go out by itself.

Why is my 2010 ford fusion is throwing code po455. no gas cap required


P0455 is Evaporative Emissions System Leak Detected (Large) and means that there is a large leak in the system probably with one of the EVAP hoses near the fuel tank or EVAP canister or maybe even A leaky purge valve.

2000 Ford Focus...DTC code PO455


code PO455
EVAP Control System Large Leak Detected
Possible Causes:


Aftermarket EVAP hardware non-conforming to specifications Canister vent (CV) solenoid stuck open EVAP canister purge valve stuck closed, or canister damaged EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube disconnected or cracked, or canister is damaged Fuel filler cap missing, loose (not tightened) or the wrong part Loose fuel vapor hose/tube connections to EVAP components Purge sensor or FTP sensor is out of calibration or has failed I would say that your gas cap is a good place to start.

2004 Chevy Cavalier 2.2 eco Automatic 94,000 miles Trouble Code: PO455 Evaporative, Emisson Control Leak, Detected Large Leak. Question: Between the EVAP canister purge solenoid valve, and the EVAP...


in my experience the usual culprit is the evap cannister. the problem is it gets moisture in it and freezes during winter thus cracking the plastic. if you lay under the car and look at the evap box it black plastic and if you see a loose or cracked hose or the box itself is cracked that is most likely it. as a side note you can check the gas cap and buy a new one to see if that rectifies the situation. lastly i don't think the gas tank should be suspect as you would probably notice if gas was leaking out of the tank. if you take the car to a dealer or shop they can do a smoke test and determine where the leak is.

I got a code of PO455 can you explain to me what that actually is??


P0455 is a Large Evaporative System Leak. Usually caused by a loose gas cap. If the cap WAS loose, tighten it up and just drive the car, it may take a few days for the computer to run the tests and and confirm that its OK and will turn the light off by itself. If the cap is tight, then make sure the seal is good, if it is, then the leak is somewhere else, usually on Jeeps I find hoses cracked near the canister, so thats where to start if the gas cap is tight and good.
