Hi,

To fix a po449 on a Chevrolet Venture will take a little troubleshooting, and probably a "scan tool" that is actually capable of sending commands to the control computer. This is because you have to "listen & feel" around the EVAP module while telling it to open & close this solenoid.

I have provided a link that has more details about this code.

Good Luck, Greg
