Code p0449
I have a p0449 code reading on my check engine light. I have replaced evap canister, evap purge valve, plug connector on canister solenoid, and gas cap. Check engine light is still on. Any suggestion?

the code is for an open in the vent valve control circuit
so if the cannister came with a new vent valve...you need to check for power to the vent valve. with key on remove the vent solenoid connector..oneof the wires should have battery voltage. if it doesn't check the f4ua fuse in the underhood fuse block. if the fuse is good the wiring is open.
