What does a purge volume control valve do?

In particular, the canister purge valve is an emissions control component that allows the engine intake vacuum to take the exact amount of fuel vapors from the EVA canister into the engine intake manifold. In newer model vehicles the purge valve is electrically operated solenoid controlled by the engine computer.

What happens when a canister purge valve goes bad?

Rough Idle

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 caused by a broken or damaged purge solenoid or any of the hoses attached to it.

Where is the purge volume control valve located?

The Canister purge control valve is most often located in the engine bay on a hose going from the intake to the canister. It can also be located near the fuel tank.

Can I 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.

How do I know if my purge valve is stuck open?

The most common problem with the purge valve is when it sticks or does not close fully. This may cause the "Check Engine" light to come on. In some cars, a stuck-open purge valve can cause difficulty starting right after refueling at a gas station: for the first few seconds the engine may run rough and stumble.

How much does it cost to replace a purge valve?

To have your canister purge valve replaced, you will pay anywhere between $110 and $170. The parts are the expensive component here, as they will run between $75 and $110. The labor, on the other hand, usually only costs about $50, meaning this is a rather quick and straightforward procedure.

Will a bad purge valve throw a code?

When a canister purge valve is stuck in the closed position, it will prevent the system from burning the evaporated fuel in the engine. This will cause a low purge flow code and can cause premature failure of the charcoal canister in the evaporative emissions system.

How long does EVAP purge valve last?

Normally the canister purge solenoid lasts the life of the vehicle, but it can wear out from time to time. If the canister purge solenoid starts to go out, the Check Engine light will come on and your car will not pass an emissions test.

How long does it take to change a purge valve?

The replacement time for the location next to the fuel tank would take about 1 hour and 30 minutes to 2 hours due to raising up the vehicle and having to remove the spare tire if there is any and to remove the fuel filler neck if its in the way.

Can a purge valve cause hesitation?

A faulty purge valve causes no start, stall and hesitation condition when the purge valve leaks allowing full flow of stored gasoline vapors into the engine or excess air, causing a no start, stall or hesitation. ... In addition to the systems listed above, you may see a check engine light.

Can you drive without a purge valve?

This valve, although it's a small component, is crucial for your EVAP system to work properly. Without it, your engine is going to have a hard time working and it will run extremely rich. This rich fuel to air mixture can also have an impact in the long run on other components in your car.
