In most cars, the EVAP vent valve is located underneath the vehicle, close to or at the charcoal canister near the fuel tank, see the photo. For that reason, it often fails due to corrosion. The most common problem with the vent valve is when it sticks open or fails.

Where is the vent control valve located?
In most cars, the EVAP vent valve is located underneath the vehicle, close to or at the charcoal canister near the fuel tank, see the photo. For that reason, it often fails due to corrosion. The most common problem with the vent valve is when it sticks open or fails.
Where is the EVAP control system located?
The EVAP emissions control canister is located on the driver side, near the rear tires.
Where is the purge valve located on a Nissan Altima?
The purge valve is located in the vacuum line between the fuel vapor containment canister and the intake manifold. It opens at specific times to let fuel vapors stored in the canister be drawn into the intake manifold and burned as part of the combustion process.
What is EVAP canister?
The canister purge valve is a vital part of the Evaporative Emission Control System (EVAP). The EVAP system seals the fuel system of your vehicle to prevent harmful fuel vapors from entering the environment.
What does a vent valve do?
The purpose of the canister vent valve, also called simply the vent valve, is to control the flow of air into and out of the Evaporative Emission Control (EVAP) system, a feature on all modern cars.
Can EVAP system cause car not to start?
Hello, typically, an evaporative emission system vapor leak will not prevent the vehicle from starting. It may cause a check engine light — but many things can cause a check engine light to illuminate.
What is purge valve?
A purge valve is an integral component of a vacuum material conveying system that not only provides an on/off flow of material into a conveying line, but also a way to purge that conveying line with air at the end of every material loading cycle.
Can gas cap cause large EVAP leak?
The EVAP system is sealed and the most common components that can cause a leak are the gas cap, vent valve, and purge valve and the hoses and connectors, see the diagram below. The first thing to check with this code is the gas cap.
What’s the difference between a vent valve and a purge valve?
The Vent Solenoid is a normally open valve that is commanded closed to seal the EVAP system and stop air flow into the charcoal canister. The Purge Solenoid is normally closed but is opened by the PCM to allow manifold vacuum in the EVAP system — thus drawing fuel vapours from the EVAP system.
