Code po449 is the canister vent valve solenoid error.This is a common problem with these valves because they are under the truck in the rear by the spare tire and they get all the dirt and water and snow,if you live in an area where you get snow.You will find it on the canister under the vehicle by the spare tire.

I do not have the PO449 code,but it is in with
the EVAP System codes
You will need professional help with EVAP Leaks,
only because they are so small, and there are a lot
of components in the system
So an EVAP Smoke Machine is used to find them.
It is about $1100 piece of equip. Fairly cheap and
fast at finding your problems.
Also a scanner may be necessary to actuate components
That is 9 grand plus 2 g for software.
No one ever puts a machine or computer on your vehicle,ever.
What is used, is a code reader or scan tool,to look at your
vehicles ECM or PCM. Your vehicle, is more of an assortment
of processors,than computers.

That's an Evap Emission Control System Vent Valve/Solenoid Circuit.
The vent valve for the emission control system is not working.
Usually it is mounted on the charcoal canister. It won't affect the running of the car,but the light will be annoying. Have the vent valve replaced.
