You can find the component numbers for OEM emissions system parts here. I wouldn’t order from them because the website is very pricey and you can obtain all the components for much less elsewhere, but it is a nice site to find the OEM part numbers. I’ll also provide a link to the service manual, which I use on a daily basis. Plenty of information there.
The Vapor Canister Vent Solenoid is mounted on a bracket just behind the rear tire on the driver’s side of the vehicle. The change out only takes ten minutes and is really easy. After removing the bolt and the bracket that is attached to it as well as the electrical plug, you are finished. After that, repeat the procedure to put it on.
I am going through a similar situation right now. I can’t figure out the P0455 error code. I began with 2 brand-new fuel caps. Light remains on. swapped out the purge valve. There is still light. The Evap vent was then changed. There is still light. I checked all the tubes, connections, and other stuff. They’re alright. performed the traditional “sniff” test. I don’t notice anything odd in the air. In a few days, I’ll replace the fuel pressure sensor to see whether it makes a difference. Additionally, the “gas cap loose” indicator on the dashboard keeps flashing even though the gas cap is not loose. Additionally, if it has been sitting for a while, it takes a lot longer to start up. However, if only five to ten minutes have passed since I turned it off, it turns on immediately. My check engine light is on, and even though I need to renew my tags, I can’t do it while the light is on. Phoenix experiences an abrupt failure. I’m hoping the problem is with this fuel pressure sensor. I’ll inform you. Also, I hope these sites are useful to you.

On a Hyundai Accent, where is the canister purge valve?
Between the intake manifold and the fuel vapor containment canister, there is a purge valve in the vacuum line. It opens at predetermined intervals to allow the canister’s fuel vapors to be sucked into the intake manifold and consumed during the combustion process.
What does a Hyundai’s purge valve do?
The vehicle’s EVAP (Evaporative Emission Control) system includes the purge valve.
The EVAP system stops fuel vapors from leaking from the fuel tank and into the atmosphere. As shown in the diagram, the EVAP system collects fuel vapors from the fuel tank and temporarily stores them in the charcoal canister.
The purge valve in contemporary vehicles is an electrically driven solenoid that is managed by the engine computer. The purge valve is shut when the engine is off. The engine computer pulses the purge valve open when the engine is operating and fully warmed up, allowing some fuel vapors to be expelled from the charcoal canister and burned in the engine. Under the hood, the purge valve may make a repetitive clicking sound as it works.
A multitude of sensors keep tabs on the purge flow. The computer turns on the “Check Engine” light if the purge flow is less than anticipated or higher than anticipated under specific circumstances.
Can you change the purge valve on your own?
The expense of replacing a canister purge solenoid is not too high and the task is rather simple. Total costs should range from $80 to $200.
The labor will normally cost between $50 and $80, while the part will typically cost between $30 and $120. Of course, this price is further increased by the applicable fees and taxes.
You can save a few dollars on labor by replacing the purge valve on your own.
What is the cost to repair a purge valve?
Your evaporative emissions control system includes a small but crucial part called the purge valve, which is also referred to as the canister purge valve in some cases.
This valve prevents gasoline vapors from escaping and entering the atmosphere. Along with other symptoms, a broken purge valve frequently causes the check engine light to come on.
A purge valve replacement typically costs $130. Depending on the make and model of your car, the replacement valve costs anywhere from $35 to $100.
The labor portion of the cost varies according to where you take the car and the hourly rate of the laborer.
Can you clean a purge valve?
Interested in learning how to clean a purge solenoid valve? If so, you are on the appropriate page.
By cleaning the internal components without opening the solenoid, debris or other impurities that prevent the purge solenoid valve from operating correctly can be eliminated.
There is nothing you can do but replace your purge solenoid valve if the solenoid malfunctions or the valve’s casing breaks.
After checking the solenoid’s coil, you can clean the valve if the housing is undamaged. Most of the time, cleaning it makes it work again, saving you the money that would have been required for repair or replacement.
A purge solenoid valve is a straightforward device with three essential components:
- a plunger (flap) and an internal solenoid that, depending on the solenoid’s condition, permits fumes to pass through (either disengaged or engaged).
- a socket that is used to control the solenoid.
- a container with two connectors for fume entry and outflow.
A purge solenoid valve is most likely to have three main issues:
- A breach in the casing, which includes the intake and exit pipes, could allow fuel gases to escape and frequently result in a vacuum leak.
- If the solenoid’s coil is harmed or severed, the flap or plunger may not move as intended.
- If the electromechanical inner portion becomes stuck from carbon or debris build-up, the purge solenoid valve may not be able to properly open and close. Most of the time, it remains stationary in one place.
The purge solenoid valve can be thoroughly cleaned either by opening it or cleaning it without opening it. Following are the steps.
Can you operate a car with a broken purge valve?
Yes, you can usually drive the car to a mechanic with a bad purge control valve without noticing any serious performance problems. However, it’s not advised to continue driving when the purge valve is broken without having it fixed. Emissions from the tank may leak if the purge valve is malfunctioning, which might be bad for the environment and your car’s performance.
What functions the EVAP purge valve?
The valve closes when your engine is off. As soon as your engine starts, the computer gradually and continuously opens the purge valve. By performing this, fuel vapor can travel from the charcoal canister and ignite in the engine. The EVAP system is made up of these components connected by a hose.
What occurs if the purge valve is trapped shut?
A stuck-closed purge valve would prevent the passage of gasoline vapors for recycling, increasing pressure inside the system. Over time, intense pressure can cause the gasket and rubber seals on the car to blow out, which might lead to an oil leak into the engine compartment and the emission system. A car may experience a more significant problem if the condition continues.
Visit a repair right away for an expedient fix if you ever notice this symptom so you can prevent further damage to your car.
What is the lifespan of purge valves?
Even though it is intended to, the purge valve sometimes doesn’t survive the entire life of the car. Your car will probably display one or more conspicuous symptoms if the purge valve malfunctions.
Why does the check engine light remain on even after I replace the purge valve?
Purge valve keeps malfunctioning. The purge valve is the cause, according to the codes, every time the engine light comes on. In the past five months, I’ve changed that out three times. What might the issue be?

EVAP purge valve stalling potential
The evaporative emission control system (EVAP) in your car includes the canister purge solenoid. The complete EVAP system, which consists of the canister purge solenoid, the charcoal canister, and the engine vacuum, are connected by a hose. Depending on the make and model of your car, the part might be inside the rear quarter panel or tucked away in a corner of the engine compartment.
The EVAP system’s main goal is to stop huge amounts of fuel vapors from entering your car and escaping into the atmosphere. Due to the compounds they contain, gasoline fumes can make people feel sick, give them migraines, and have respiratory issues if they breathe them in. Toluene and benzene are a couple of these substances.
The canister purge solenoid often lasts the entire life of the car, but it occasionally wears out. Your automobile won’t pass an emissions test if the canister purge solenoid starts to fail, which will cause the Check Engine light to illuminate. Additionally, the accumulation of gases inside the canister may result in stalling or misfiring in your car.
Activated charcoal is used in the canister purge solenoid to absorb the gasoline vapors. Until you start the car and start driving, activated charcoal sucks up and absorbs the fuel vapors. The powertrain control module, or PCM, then opens the canister, allowing the intake vacuum to draw the vapors into the engine through the tank vent line. Since activated charcoal does not deteriorate over time, a canister shouldn’t require replacement unless it is broken or otherwise damaged.
Due to regular driving clogging the canister with dirt and dust, the canister purge solenoid may malfunction. In addition, the canister may shatter as a result of adverse environmental factors. If this occurs, the canister purge solenoid needs to be replaced because it could damage other parts of your car.
What signs would point to a bad EVAP purge solenoid?
Rough idling, difficult starting, and the Check Engine Light coming on are typical indications that a car’s EVAP canister purge solenoid isn’t working properly.
How much does repairing P0441 cost?
How much will repairs cost? Typically, it will take one hour of labor to identify the P0441’s root cause, costing you $75 to $150 depending on the business you go to. Although they are not particularly expensive, the replacement parts for this service will raise your overall cost.
How can I fix the P0441 error?
You must first diagnose error code P0441 to ascertain the precise nature of the problem before you can fix it. Two of the most popular remedies for this error code involve replacing the gas cap and purge valve. However, there may be further problems that result in this code, such as disconnected or harmed connections in your EVAP system.
What signs indicate an EVAP leak?
- The Check Engine indicator is on.
- poor fuel efficiency
- The service fuel system light is on.
- driving when stalling or surging
- Engine stuttering or misfiring
- Low or absent power.
- In the cabin, you may smell burning carpet or petrol.
- a lot of smoke coming from the exhaust pipe
How far must you travel to turn the check engine light off?
You are urged to do any required repairs or make sure the aforementioned component is working correctly for best results.
Connecting the OBD2 scanner first
Start by joining the OBD2 scanner to the diagnostic port of the car. Start the engine and allow the code reader to display the codes for the check engine light.
2. Delete the error codes
Continue by erasing the recorded check engine codes using the code reader’s user interface. When you’re finished, no error messages ought to show up. At this moment, you can turn off the engine.
3. Log a few miles
Drive your car between 30 and 100 miles to ensure the check engine light does not come back on. The “Drive Cycle” of the car can then be reset because the various sensors need time to calibrate.
The “driving cycle” must register as ready and the check engine light must remain off if you intend to perform an emissions test. Drive cycle readiness is often achieved after 50 to 100 miles of driving, however it’s better to consult your dealership or mechanic regarding the applicability for your particular vehicle.
