Where does the purge valve connect to?
EVAP Canister The vapors are stored in the canister until the engine is being driven. The PCM then opens the canister purge valve, which allows intake vacuum to draw the vapors into the engine. The EVAP canister is connected to the fuel tank through the tank vent line.
What happens when your purge valve goes bad?
If the canister purge valve fails and sticks open, it will create a vacuum leak that can affect the engine idle speed and quality. A vacuum leak can also be created if the purge solenoid, or any of the hoses that may be attached to it break or become damaged.
How does a purge valve work?
In modern cars, the purge valve is an electrically-operated solenoid, that is controlled by the engine computer. When the engine is running and fully warmed up, the engine computer gradually opens the purge valve to allow some amount of fuel vapors to be moved from the charcoal canister and burned in the engine.
How hard is it to change a purge valve?
The canister purge valve replacement and the cost ro replace the purge valve is generally a simple and easy procedure, since there might be just one valve to replace in your car.

When should purge valve open?
When your engine is off the valve is closed. Once your engine is up and running the computer continuously and moderately opens the purge valve. This action allows fuel vapor to move from the charcoal canister to burn in the engine. A hose connects all of these parts to form the EVAP system.
Is it okay to drive with a bad purge valve?
It’s certainly possible to drive with a broken purge valve, but we don’t recommend it. The longer you drive with a bad valve, the more risk you run of damaging the vehicle’s EVAP system and other parts. There’s also the possibility of wasting fuel and pumping out more emissions than is necessary.
What is a purge valve and how is it used?
The purge valve, also known as the canister purge valve, is part of your vehicle’s evaporative emission control (EVAP) system. It traps the fuel vapors created in your fuel tank and prevents them from escaping into the air. The valve operates using a solenoid, which can sometimes malfunction and cause it to become stuck open or closed.
What does the purge valve do?
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. Air purging is vital to prevent contamination…
How do you replace a purge valve?
Step 1: Go under the rear of your car and locate the purge valve. Step 2: Remove the connecting hose and the screws on the valve. Step 3: Once the screws are out, slide the valve out of the canister and gently try to remove the electrical connector on the valve. Step 4: Install the replacement purge valve.
What is the purpose of the purge control valve?
The canister purge valve is a vital part of the Evaporative Emission Control System (EVAP). The purpose of the EVAP system is to prevent large amounts of fuel vapors from escaping into the atmosphere and from getting into your vehicle.
