DTC P0449 Evaporative Emission (EVAP) Vent Solenoid Control Circuit

The Evap canister vent valve is located on the canister itself under your car just in front of the fuel tank. #26 in the picture.

Check the wiring associated with it, and that everything is plugged in tight. Might just need replaced.

2005 Cobalt EVAP sensor code P0449

I replaced the sensor with a used one that has no check engine light on it and the light still comes back. The plug and wiring look good and I have power to the red wire but get nothing in the white wire to the sensor. Not a ground or power with the key off, key on or the engine running. Both sensors were the same. Any other ideas??
