SOURCE: P0449 Evaporative Emission Control System Vent

While looking for the location of the vent/solenoid for you, I came across a blog that said this error can be caused by a loose or faulty gas cap. You may want to look at that first and possibly solving the problem. Replace the cap, get autoparts store to reset the code and see what happens.

There is a solenoid that open and closes with 12 volts, usually located close to the fuel filler tube area. This open to allow you to fill your tank, then closes after some inputs for the computer are satisfied, and then a pressure sensor verifies the system is working. First, make sure the cgas cap is tight, and if the light doesn't go away in a couple days of normal driving, get the solenoid checked.

    Check engine light on steady, and codes 0445 & 0449 from computer


    The codes you list are generic and unfortunately the descriptions provided are too. Do a bit of research into the applicalbe parts and you'll likely find a trend of malfunctions and repairs for your particular model year. After that it's time to either get greasy or see the mechanic, doesn't sound like it will be too bad, though.

    I have a 2001 pontiac grand am se v6 . The service engine soon light came on and i got a free diagnostic ran and it brought up these codes; P0443, P0449, and P0141.


    PO443, Evaporative Emission Control System Purge Control Valve Circuit Malfunction
    PO449, Evaporative Emission Control System Vent Valve/Solenoid Circuit Malfunction
    PO141, Oxygen Sensor Heater Circuit Malfunction (Bank 1 Sensor 2).
    I don't understand why the free diagnostic didn't come with a service recommendation?
    P.S. I hope that you know when one of your headlights are out!
