Hey buddy don't go so far. Check the tank cap first
P0449 Evaporative Emission Control System Vent Valve/Solenoid Circuit Malfunction
Evaporative Emission Control System control valve malfunction. You need a new evap control surge solenoid valve.
This ODB code could indicate a problem with any part of the evaporative emission control system: gas cap, rubber hoses, canister, or purge solenoid.
where is the evaporative emission system vent valve control on a 2000 galant 4 cly engine
It is located on the upper right rear of gas tank. You have to remove tank to access it.
It is mounted to the frame of the truck just in front of the fuel tank.
The car should be taken to a mechanic if the owner doesn't know what he or she is doing. Otherwise, there are books for each type of car that can be gotten to help fix almost anything wrong if the person knows what they are doing.
install updated vent control solenoid valve and jumper harness.
Usually the problem with this code is an open vent solenoid valve. 12 volts is provided to solenoid and the pcm grounds the solenoid. When the pcm checks the circuit it is looking for 12 volts on the wire at pcm. The pink wire should have 12 volts and the white wire should be the ground circuit from the pcm. Ohm your vent valve it will probably be open.
In a 2000 Toyota Corolla, the canister vent valve solenoid is typically located near the evaporative emission canister. To find the exact location, you can follow these general steps: Locate the evaporative emission canister: The canister is usually positioned in the engine compartment or underneath the vehicle, near the fuel tank. It is a rectangular or cylindrical-shaped component. Trace the vent hose: The vent hose is connected to the evaporative emission canister. Follow this hose to locate the canister vent valve solenoid. The solenoid is typically mounted on or near the canister itself. Inspect for an electrical connector: Look for a wiring harness or electrical connector connected to the canister vent valve solenoid. This connector provides power and control signals to the solenoid.
