DTC P0446 — EVAPORATIVE EMISSION CONTROL SYSTEM VENT

CONTROL LOW INPUT

DTC DETECTING CONDITION:

Two consecutive driving cycles with fau

 

I would check the the vent valve connector first there maybe corrosion at the connector causing it not to operate and trip the P0440 code

The vent valve is under the lower right rear quarter panel , just above the carbon canister (black box )

 

For the leak you will want to check the gas cap for proper seal on the fill tube ,also check the carbon canister for any damage . Sometimes if you back into a snow pile that is iced up and crack the canister which causes a leak

 

 

Hope this helps
