Hello,

I have managed to pull the above noted codes...both at the same time (?)...I have read previous posts but would welcome any other ideas. Looks like a Vent Control Solenoid?

DTC P0440 — EVAPORATIVE EMISSION CONTROL SYSTEM
MALFUNCTION
 DTC DETECTING CONDITION:
 Two consecutive driving cycles with fault
 TROUBLE SYMPTOM:
 Gasoline smell
 There is a hole of more than 1.0 mm (0.04 in) dia. in evaporation system or fuel tank.

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

(PS the car is a manual transmission , right? )
