What is a Canister Purge Valve?

A canister purge valve, mostly known as a purge valve, is a principal component of your car’s EVAP or evaporative emission control system.

Due to this system, fuel vapors created in the fuel tank can’t escape into the environment as a charcoal canister catches & collects the fuel steams. A solenoid is used to operate the purge valve. Sometimes the solenoid doesn’t function properly. Consequently, the valve starts failing.

What does a canister purge valve do?

The purge valve catches the fuel vapor from your car fuel tank and stores the vapor in the canister for a limited time. When your vehicle engine runs under a certain condition, the vapors are expelled to the engine and burn inside it. The canister purge valve will control how much fuel vapor will eject from the canister to the engine.

In late car models, the purge valve will function automatically and be controlled by the engine computer. The purge valve will remain closed when your car engine is off. When you run the engine, and it gets warmed up, the engine computer starts opening the valve to let the fuel vapor move from the canister to the engine. Several sensors control the vapor flow.

What are the symptoms of a bad purge valve?

The following signs let you determine about the purge valve failing.

Check Engine Light Will Illuminate: The first symptom that lets you identify a susceptive purge valve is- the check engine light. If your car computer senses an unexpectedly high or low purge flow, it will light up the check engine light.

Decrease fuel efficiency: A decreased fuel efficiency is another sign of a faulty purge valve. If your canister purge valve doesn’t function correctly, it causes the fuel vapor to burn to escape. Consequently, your vehicle requires more fuel to generate power, which reduces fuel economy.

Engine Issues: A vacuum leak will form if your car canister purge valve is stuck open. It affects your vehicle engine severely. Due to the vacuum leak, an unexpected volume of air will flow into your engine that your car computer couldn’t monitor. It will mess up the air to fuel ratio, causing your vehicle rough idling. Plus, you can have trouble starting or other engine issues.

How much is a purge valve?

Generally, you need to spend around $55-$110 to get a high-quality and expensive canister purge valve. You can also get a better-quality purge valve at a lower cost. And the labor cost of replacing a purge valve will be around $50. It means changing a valve is a simple task and doesn’t take a long time.
