What does the canister purge solenoid do in a charcoal engine?
The EVAP system traps this vapor in a charcoal canister and recirculates it for use as fuel for the engine and prevented from polluting the environment. The canister purge solenoid — also referred to as an EVAP canister valve — is responsible for “purging” the EVAP system by acting as the switch that allows the vapor into the engine.
Can a bad canister purge solenoid cause poor gas mileage?
Poor gas mileage is another sign of a [&failing&] [&canister&] purge valve. The [&fuel&] [&vapors&] your car usually uses for combustion [&will&] end up vented through the EVAP [&canister&] instead.

Where is the purge valve on a canister?
Generally, the valve is mounted within the engine compartment, although it can be mounted directly on the canister. Typically, the purge control valve is a normally closed solenoid valve. It requires a circuit current to act to open the valve, whilst it works against a closing spring.
Is the purge control valve a solenoid valve?
Typically, the purge control valve is a normally closed solenoid valve. It requires a circuit current to act to open the valve, whilst it works against a closing spring. The solenoid valve will have an ignition feed on one side and an ECM controlled switched-earth PWM voltage on the other.
What are the symptoms of a bad canister purge solenoid?
Cost of Replacing a Bad or Failing Canister Purge Solenoid. Common signs of a problem with a car EVAP canister purge solenoid include rough idle, difficult starting, and the Check Engine Light turning on. Our certified technicians can come to you and diagnose the problem.
What is the rating of the canister purge solenoid?
Average rating from 4,869 customers who received a Check Engine Light is on Inspection. The canister purge solenoid is an emissions control component that is commonly found on the evaporative emission control system (EVAP) of many modern vehicles.
Generally, the valve is mounted within the engine compartment, although it can be mounted directly on the canister. Typically, the purge control valve is a normally closed solenoid valve. It requires a circuit current to act to open the valve, whilst it works against a closing spring.
What are the symptoms of a bad purge solenoid?
Usually, a bad purge solenoid will display any of the following 5 symptoms that can alert the driver of a potential problem in need of servicing. 1. Rough Idle One of the first symptoms that a faulty canister purge valve may produce is a rough idle.
How does a solenoid valve work on a canister?
The canister volume will also have a fresh air inlet via a one-way (or solenoid-controlled) vent valve. Fuel vapors are purged from the canister when a vacuum is present on its outlet. Therefore, canister purging occurs when the intake manifold pressure is below atmospheric pressure, such as when the engine is idling.
Where is the purge valve solenoid located on a car?
The other location is behind the fuel tank under the vehicle next to the charcoal canister. The replacement time for the location on the engine would be about 30 to 45 minutes as the intake tubing would need to be remove to access the part.
What are the symptoms of a failing canister purge valve?
The canister purge valve is electrically operated, and is also referred to commonly as a solenoid. The most common purge valve issues are when the purge valve is stuck open or closed, or does not open at the proper time. The symptoms are listed below that may indicate your canister purge valve is not functioning properly.
Where is the vapor canister purge valve located?
Vapor Canister Purge Valve Location Depending on what you drive, there are two typical locations for the vapor canister purge valve. 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.
What are the symptoms of a bad canister purge valve?
One of the first symptoms that a faulty canister purge valve may produce is a rough idle. In this case, you will notice the car running inconsistently while stopped or driving at low speeds. If the canister purge valve fails and sticks open, it will create a vacuum leak that can affect the engine idle speed and quality.
How much does it cost to replace a canister purge valve?
The parts, depending on the car you drive, can be priced between $65 to 125, while the labor, which takes less than an hour to complete, will be anywhere from $40 to $85. For example, on Amazon.com, the best selling canister purge valve parts can retail for about $20 to $50.
What is the function of a canister purge valve?
The canister purge valve serves as part of the emission control system in a car, and it measures the flow and amount of fuel vapor that is recycled into the combustion process via the charcoal canister, or fuel vapor storage device.
What are the symptoms of a bad EVAP canister?
Symptoms of a Bad or Failing Evaporative Emission Control Canister. Common signs include the Check Engine Light coming on, raw fuel smell coming from the back of the car, and a collapsed or leaking fuel tank.
What happens when a canister purge valve is opened?
When a canister purge valve opens, the fuel vapors are sent to the engine where they are burned up. But when there is a problem with the EVAP system like a bad purge valve, the fumes escape, causing that gasoline-like smell on your car.
Can you drive a car with a bad purge valve?
The purge valve works in sync with the charcoal canister to recycle emissions as they should be removed through the internal combustion process. While you can still drive your car with a bad purge valve, you will only expose it to further damage not only to the EVAP system, but as well as to the other parts in your vehicle.
The EVAP system traps this vapor in a charcoal canister and recirculates it for use as fuel for the engine and prevented from polluting the environment. The canister purge solenoid — also referred to as an EVAP canister valve — is responsible for “purging” the EVAP system by acting as the switch that allows the vapor into the engine.

How does a canister purge valve work on a car?
This system restricts the fuel vapours created in your fuel tank from escaping into the atmosphere by trapping them in a charcoal canister. When your engine begins to run at regular speed, the EVAP system slowly allows these vapours to be released into your engine, which burn like regular fuel.
Usually, a bad purge solenoid will display any of the following 5 symptoms that can alert the driver of a potential problem in need of servicing. 1. Rough Idle One of the first symptoms that a faulty canister purge valve may produce is a rough idle.
What happens if you have a canister purge solenoid leak?
If this happens, you may notice a few telltale signs. For one, your check engine light will illuminate. Emissions are closely monitored in modern cars, so if there’s a leak somewhere, your ECU will alert you. Because combustion relies on these vapors for top performance, your mileage will suffer if they aren’t released into the engine.
How does the fuel canister purge system work?
Modern vehicles are equipped with an EVAP system that works to reduce the evaporative emissions pollution that can come from the vehicle’s fuel tank, which is released in the form of vapors. The EVAP system traps this vapor in a charcoal canister and recirculates it for use as fuel for the engine and prevented from polluting the environment.
Is the canister purge valve part of the EVAP system?
The canister purge valve is an integral component of the EVAP system, but also one that is subject to failure over time. What is a canister purge solenoid, and how can it make or break an EVAP system?
