It also depends on how much damage has been caused by the damaged purge valve, affecting how much it costs to replace the purge valve. 


If black smoke is coming out of the exhaust due to the damage caused, then the repair involved by the mechanic will end up being a higher price, and it will be a higher cost to replace the purge valve. 

The benefit of canister purge valve replacement

Symptoms of a bad or damaged canister purge solenoid


Very similar to the canister purge valve, the canister purge solenoid is a key part of the car’s mechanisms. The canister purge solenoid is a component within the emissions system just like the canister purge valve, and is found on the evaporative emissions system, also known as the EVAP system, of many modern cars. 


Cars on the market today are equipped with the EVAP system that works to reduce the pollution that can be emitted from your car and the vehicle’s fuel, which is released in the form of vapors from your car. This emissions system is in charge of trapping this vapor so that it can be used as fuel for the engine. 


The canister purge solenoid is the part of the EVAP system that is responsible for cleaning and unclogging the EVAP system, by acting as the switch that lets the vapor into the engine, and meaning that if or when the purge solenoid fails it can cause issues for the EVAP system and the emissions output levels. The canister purge solenoid performance directly affects the ability of the canister purge valve to work and the overall price of the cost of a canister purge valve replacement. 


In order to see how the canister purge solenoid can directly affect the canister purge valve, then there are three key symptoms of a failing solenoid that you need to know.

Rough idle


One of the first symptoms of a faulty canister purge valve that requires a valve replacement is that of a rough idle. If the canister purge valve fails and remains open for a long period of time, then it can create a vacuum leak that can negatively affect the idle speed of your engine and the quality of the performance of your engine. The vacuum leak can also occur if the canister purge solenoid occurs or becomes damaged over time, altering the price of how much it costs to replace the purge valve. 

Difficulty starting the car 


Another sign that is usually associated with a faulty canister purge valve and can affect the overall cost of canister purge replacement is difficulty starting your car. If the canister purge valve fails and causes a vacuum leak as a result of a problem with the canister purge solenoid, then the air can flow into the engine and damage the air to fuel ratio. This gives you a better idea of how much it will cost to replace the purge valve. 

Check Engine Light on


A defective canister purge solenoid that is no longer working might also turn on the Check Engine light on your dashboard. Although this can mean that there are various issues in your car, the check Engine Light is also a clear sign of issues with the canister purge valve itself. If the computer in your vehicle notices any problems with the purge solenoid circuit or the signal coming from mtech purge solenoid valve, it can turn on the Check Engine Light to tell the driver there is an issue that needs to be fixed. This light can also be caused by various other issues, so it is recommended to have your car analyzed by a mechanic to scan for diagnostic trouble codes so that you can figure out how much it costs to replace the purge valve. 

Lower Gas Mileage


If your canister purge valve is not operating in the right way, then it might negatively affect your gas mileage and fuel economy. The reason for the lower gas mileage is that the vapors that your car uses in combustion within the engine can find its way into the EVAP canister and eventually be churned out to the environment, meaning that you will lose some of the fuel vapors that you are burning. 

How to replace the purge valve


The procedure is not uniform for every single canister purge valve, so it will depend on the make, model and year of your car that you are trying to get repaired or fixed. Some of the purge valves are near the fuel tank in your car, while others are located closer to the engine, and the technician will need to determine where the purge valve is in your specific model of car. This allows them to analyze the purge valve and diagnose the condition before taking it apart or figuring out how much it costs to replace the purge valve. 


As soon as the technician finds the purge valve, he will have to remove the parts that are in the way, which can be determined by where it is located in your car. This could be a various number of parts, and they will vary based on the location of the purge valve. The purge valve will need to be disconnected from any tubes or hoses, and a new purge valve will be installed, which affects the cost to replace the purge valve.

When to replace the purge valve


Usually, the mechanic will be able to tell when the canister purge valve is damaged or has failed by their visual inspection. Although you can still drive the car, you can cause further damage to your vehicle if you continue to drive on it, as well as to other parts. The more you drive the car on a damaged canister purge valve, the more that you will damage other components. You will need to fix the problem eventually, but try not to let it sit too long, despite not being an immediate and necessary fix. 


If you are driving and notice black smoke coming out of the exhaust pipe in your vehicle, then you need to stop driving your car right away and bring it to the mechanic so that you can fix your problem as soon as possible. If you do not bring your car to the mechanic, then you could end up damaging serious parts like the catalytic converter. 


The price to replace the catalytic converter replacement is very expensive, with the average cost of the repair being between $945 and $2475 depending on the type of car you have, and including parts and labor. This is much pricier than how much it costs to replace the purge valve. 


Most vehicles will not be able to experience canister purge valve failures very often, but a few cars will experience the purge valve failure that requires the replacement. 

How to save money on replacing the canister purge valve


If you want to save money on replacing the canister purge valve, then you should check around your local area for the best rate from various mechanics. The price of labor and parts could be different from one mechanic to another in your area or the surrounding areas, but you are not likely to see a big difference with the prices of this fix or repair. 


However, if you have some repair knowledge and some of the right tools, you can always try and do this job yourself to save some money and time by avoiding going to the mechanic. It won’t take you very long and it is definitely not as complicated as other repairs and replacements that can be done on your car. Instead of working on the engine or the transmission, this repair of the canister purge valve is easy and quick.


However, despite being fast you should still have researched the topic and know what you are doing. You can end up damaging the vehicle more or not putting in the parts correctly if you are inexperienced and have no experience with repairing a car or a part in your vehicle.
