SOURCE: evap system vent control circuit low

There is air escaping from the gas tank. Often a problem with the gas cap, try tightening the cap, reset the code and see if it comes back on. Essentially it is testing for cracks in the tank.
Also remember just because there was a condition that activated the sensor does not mean it still exists. Have the codes reset. If it comes back it may be a bad seal on the gas cap. But just incase keep an eye out for possible leaks.
Auto Zone can read codes they may also be able to reset them. If not try disconnecting the battery for 10 minutes to see if that will reset the codes
Hope this helps.

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.

What makes my Chevy malibu 2005 v6 put system code po449 out


P0449 - OBD II Trouble Code Evaporative System Vent Valve/Solenoid Circuit Malfunction Our emissions expert has put together the following information about the P0449 fault code. We have also included diagnostic procedures you can take to your repair shop if the mechanic is having difficulty analyzing the code.
OBD II Fault Code
  • OBD II P0449
Fault Code Definition
  • Evaporative System Vent Control Circuit Malfunction
What does this mean? The evaporative control (EVAP) system captures any raw fuel evaporating from the fuel storage system (e.g. the fuel tank, filler neck, and fuel cap). Under precise operating conditions-dictated by engine temperature, speed, and load-the EVAP system stores and purges these captured fuel vapors back into the combustion process. The carbon canister, which stores the raw fuel vapors, utilizes a vent valve that allows fresh air to enter the EVAP system. This displaces the fuel vapor as it's purged into the combustion process. Code P0449 indicates that the evaporative control (EVAP) system vent valve solenoid is malfunctioning. This can be caused by either too little or too much electrical resistance or a mechanical problem with the vent valve itself. Symptoms
  • Check Engine Light will illuminate
  • In most cases, there are no adverse conditions noticed by the driver
  • In some cases, there may be a noticeable fuel odor caused by the release of fuel vapors
Common Problems That Trigger the P0449 Code
  • Missing fuel cap
  • Defective Evaporative Vent Valve
  • Defective or damaged fuel cap
  • Distorted, damaged or cracked Fuel Tank Filler Neck
  • Torn or punctured Evaporative system hose(s)
  • Defective Fuel Tank Sending Unit gasket or seal
  • Split or damaged Carbon Canister
  • Defective or damaged fuel tank
Common Misdiagnoses
  • Fuel cap
  • Evaporative Purge Valve
  • Evaporative Vent Valve
Polluting Gases Expelled
  • HCs (Hydrocarbons): Unburned droplets of raw fuel that smell, affect breathing, and contribute to smog

We hooked up an OBD11 Auto Scanner to our 2005 Chevy Silverado 1500 pickup and got the codes P0449 and P0455 What do they mean and can we fix it ourselves or do we have to take it in.


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.

who do i contact to sue gm? after the n.h.t,s.a told gm on 5-23-73 to recall all 1993 saturns gm refused 29 days later i was in a accident that the n.h.t.s.a wanted recalled for a serious saftey problem i suffered a permanent tramatic brain injury and i wrote a letter to mary barra gmsc-e-o.she handed my letter to a jeffery koppy gms lead counsel who replied by a letter to me that was the old gm and because we filled bankruptcy in 2009 the new gmis not taking any futher action in regards to your letter.it took the feds to get gm to finally get the car recalled on 8-10 93 while i was still in the hospital.it gets worst i was a employee for gm at the time.because of my head injury i can't ever work again. i still had 17 years to work for gm and to get my 30 years to retire which was to be may of 2010.instead i had to retire a little after the accident.the day after accident iwas supposed to sign my transfer papers to another gm plant in michigan i was employed at their wentzville mo. plant because i was in a coma for 3 weeks and in the hospital 3 months that transfer never happened and the house we had at the time of accident was all ready sold. we had to get a lawyer so we could remain there. because my one car accident happened so close to where we lived.it happened on the i-70 expressway in warren county in the city of warrenton mo. all our neighbors knew about it. i was told by my doctors to try and do phyical therapy as much as possible.so my wife took me for a walk almost every day.but all our neighbors knew of what happened to me they just staired at me every day.it made me feel like a freak.so we sold the house and moved to the country.and if all that wasn't bad enough when my youngest daughter finished nursing school she asked me if i would co sign a loan for her in 2002 for a new car i still got my gm discount and because my brain wasn't right i told her to go to the gm dealer in the city i lived in because the sales-man was a very good man. and over the years we bought new cars from him i felt we were good friends.the car my daughter bought was a lemon from the time she bought it.it had nothing to do with the salesman or dealer. it was a 2002 chevy malibu.well one day she gave a friend a ride home and as she pulled into friends driveway the ignition just turned off.like it did to those 124 people who died because of a problem gm knew about for a long time. my daughters ignition failed in 2004 so she had the car towed to the closest dealer .they said the ignition was bad and said she needed a new one so she told them to go go ahead a replace it even gm had long knew of the problem she had to pay to get it replaced.then if you's can believe this about 10 years later i think it was 2013 or 2014 she got a recall letter telling her that the gm dealer put in another bad ignition.try keep sending her recall letters.but with gm almost killing her dad plus alot of other people wih cars with bad ignitions. she said theres no way gm will tought her car as usual it wasn't running any ways.so it just sat there and she got tired of looking at it and she just called the junk yard i forget how much she got but said she was just glad it was gone and could never hurt anybody ever again.but i'm not dead yet and i still want gm to pay me for what they did to me.as far as i'm concerned gm should be forced to stop making cars.think of all those children who lost their mother or another family member because of gm.i guess so many companys are out for the most money than can make their using defective parts. before i sign off i would like to say the plant i worked at in wentzville mo.had the most inspectors and process assurance inspectors that it almost impossible for something to slip by.i can see if a car rolls out missing a nut or bolt from time to time but there is no reason anything saftey related to ever be missed,from what i found out about the saturn car that almost killed me the bad positive battery cable that shorted out every thing in the car like air bags and abs brakes with no air bags to deploy thats why i was ejected head first out thru the front windshield.i'll bet it hurt alot but doctors said i was knocked out instantly.BUT just because i was in a coma my wife who is a nurse said i was thrashing around moaning that they kept giving me alot of morphine shots.so i'm very tired now using one finger to type on computer.so before yous buy a new car make damn sure there aren't any recalls on it jay teffer signing off.watch what car you decide to buy!!!!!!!!!
