On my 05 avalanche it's located behind the gas tank,over the frame.It look's like a cylinder and has a 2 prong wire going to it and a 5/8 hose shrink wraped to it.
The evap emission control system vent valve solenoid on a 2007 Avalanche is typically located near the charcoal canister, which is usually in the rear of the vehicle, near the fuel tank. You can consult the vehicle's service manual for specific instructions on locating and replacing the vent valve solenoid.
A P0449 code on a Chevy Avalanche typically indicates a problem with the evaporative emission control system vent valve/solenoid circuit. This may result in issues with fuel vapor escaping from the fuel tank. It is recommended to have a professional diagnose and repair the issue to prevent potential fuel system problems.
This ODB code could indicate a problem with any part of the evaporative emission control system: gas cap, rubber hoses, canister, or purge solenoid.
P0449 Evaporative Emission Control System Vent Valve/Solenoid Circuit Malfunction
install updated vent control solenoid valve and jumper harness.
Evaporative Emission Control System control valve malfunction. You need a new evap control surge solenoid valve.
P1443 Evaporative Emission Control System - Vacuum System - Purge Control Solenoid or Purge Control Valve fault Loose or defective gas cap will cause this code.
where is the evaporative emission system vent valve control on a 2000 galant 4 cly engine
Can't!! EVAP is the system that purges and burns vapors from gas tank. It either holds pressure like it should or has leak. Or the vent solenoid or control of solenoid is inop.
If it is the valve on top of the fuel tank, it weel need to be replaced.
It is mounted to the frame of the truck just in front of the fuel tank.
