SOURCE: Getting codes P0455 and P0449. From what I read,

The vent solenoid valve has been redesigned to correct the problem you are having. I would recommend purchasing the dealer component.
I am not aware of any aftermarket parts suppliers.

SOURCE: We hooked up an OBD11 Auto Scanner to our 2005

P0449 has to do with the Evap System. The problem could be with wiring short circuit, Could be the EVAP canister purge valve or the ECM.
P0455 has to do with the evap system as well. Could be a leak in one of the hoses to the evap system so you need to check all lines to the evap system. There is also one hose that connects to the top of the tank that we have seen come loose. Could also be a intake leak or a problem with the Canister purge valve. You can fix these yourself somewhat. I would trace down all the lines first to see if anything has come loose under the vehicle to the Black plastic EVAP canisters. Without being able to check the valves you will probably have to take it to a shop to have them checked out or pay the price to replace the valves and gamble they are the problem.

SOURCE: 01 dodge ram 1500 5.2 4WD code P0455 evap system leak.

This code will not stall or no start of your engine, evap only work when engine is off, it is to reduce the fume your gas tank lets out to protect the o zone, but it will not pass Emission test, also could be some thing a small as your gas cap not sealing right.

    My check eng. light came on and I had it checked and the two codes p0455 &p0449 showed up, what should I do about this?


    P0455 stands for evap emissions detection leak and p0449 stands for evap emissions vent control circuit. You should go to a parts store and see if your able to purchase and install. Best of luck!

    2005 chevy 1500 silverado eng. light on ran code p0455 and p0449 how to fix the problem. and how much work it takes. thanks STEVE.


    P0449 is the evap vent valve solenoid circuit malfuntion.
    P0455 is an evap gross leak
    Perhaps the gross leak code has to do with the vent valve. Find the vent valve. It should be near a rectangle evap canister. Maybe under the bed. The small vent line from the fuel tank will go to it. The solenoid is near the cansiter. With the key off the valve will be open. With the key on it should be closed. You may try disconnection the hose and blow through it with both key off and on and see if air will pass through. If the valve has died and is stuck open, that can be the huge leak.

    If it is not the leak then a smoke machine should be used. Easier than searching the lines for bad o-rings, splits, or whatevers.

    I have a 2007 Chey silverado, and the two codes came up, P0449, and P0455. i know one is a large leak in the emissions system and not sure what the other one is. Should i get it hooked up to a fogger or...


  • P0449 - Evaporative Emission (EVAP) Vent Solenoid Control Circuit
  • P0455 - Evaporative Emission (EVAP) System Leak Detected

  • Many times this is caused by the canister vent solenoid. You can definitely hook the smoke to it but quite often is just that particular solenoid malfunctioning.

    I have a 2003 Chevy silverado and I'm getting a p0455 code, what's does that mean


    P0455 Evaporative Emission System Leak Detected (large leak)
    The large leak detected could be in a hose or connector leading to the front under the hood evaporative canister.

    It is not a loose gas cap, though.

    My check engine light is on and I am getting codes P0449 and P0455. What is this and how do i fix it?


    The p0455 is for a leak concern and if that was the only code I'd say give the cap a shot. However the p0455 is most likely just a side effect of the P0449. The P0449 is a test that is run on the vent solenoid circuit to check the electrical functions in basic terms. The computer is putting out voltage amount X and in a properly functioning circuit it knows it will see voltage amount Y come back. It isn't coming back as what it expects to come back at so there must be something electrically wrong with the vent circuit. And of course if the vent doesn't work you get a large leak. If we are just throwing parts at trucks the logical one for you is a vent valve. Since your Vue is a 2008, most likely there is a good chance that it's covered under the emission warranty which is 5 years.
    Thank you for using fixya. and be safe.

    Have a p449 code on my 2003 silverado


    P0449 and P0455 has to do with the Evap Canister control solenoid which causes a large vacuum leak. I think the replacement part number is 19207763. The part is located back by the fuel tank, mounted to its side.

    P0135 is a bad 02 sensor
    P0442 is a evap problem

    i would check the vent solenoid first its a 4ws fuse under the hood in the fuse box make sure you have power to it you should have power at all times the ground comes from the pcm i think if you fix this everything else will work they are all computer controled
