Where does the canister purge solenoid come from?
The canister purge solenoid is an emissions control component that is commonly found on the evaporative emissions (EVAP) system of many modern vehicles. Modern vehicles are equipped with an (EVAP) system that works to reduce the evaporative emissions pollution that can come from the vehicle’s fuel, which is released in the form of vapors.

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 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.

What happens if the canister purge valve fails?
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 created if the purge solenoid, or any of the hoses that may be attached to it break or become damaged.
How to tell if an EVAP purge valve is failing?
Poor Engine Performance On top of a rough idle, a vehicle with a failing EVAP canister purge valve will display signs of poor engine performance. The engine may feel like its running “weak” and won’t generate sufficient power for acceleration. Accelerating will feel like you’re pressing the pedal down and moving slower.
When to replace an evaporation vent solenoid?
The component failure itself prevents fresh air from entering the EVAP system that will negatively impact the operation of the EVAP system. This triggers a check engine light or may cause the vehicle to not start in some worse case scenarios. If the EVAP vent solenoid is malfunctioning, it must be replaced.
How does the EVAP purge solenoid work in a car?
Hydrocarbon is distributed by the EVAP purge solenoid into the fuel system and burnt during the combustion process. The filtered hydrocarbons are converted to carbon dioxide and released back into the air by the EVAP vent solenoid. This component is typically in an open position when the vehicle is running and closes when the vehicle is turned off.
How do you remove an EVAP vent bracket?
Using a flat blade screwdriver, carefully depress on the clip and slide the EVAP vent solenoid off the bracket. Step 9: Remove the old EVAP vent solenoid. After you’ve released the clips and unbolted the unit, it should come off the vehicle rather simply. In some cases, there is a secondary ground wire attached to the unit.
How does the air conditioner solenoid system work?
It works by allowing air into a charcoal-based canister which becomes pressurized when vapor enters the chamber. Once the solenoid is triggered, air is introduced to the EVAP and relieves pressure on most US and domestic cars, trucks and SUV’s.
Can a defective canister set off the Check Engine light?
A defective canister purge solenoid may also set off the Check Engine Light. If the computer detects any problem with the purge solenoid circuit or signal, it will set off the Check Engine Light to alert the driver that a problem has occurred.
What causes a check engine light on a purge solenoid?
If the computer detects any problem with the purge solenoid circuit or signal, it will set off the Check Engine Light to alert the driver that a problem has occurred. A Check Engine Light can also be caused by a wide variety of other problems, so it is recommended to have the vehicle scanned for trouble codes to be sure. 5. Low Fuel Economy
How does the vapor canister purge valve work?
The Evaporative Emission Control system features a vapor canister purge valve which manages the quantity of fuel vapor coming out of the charcoal canister. The purge valve used to be controlled with a vacuum but now, newer cars allow the engine control unit to electronically control it.
Where is the purge valve in a car?
There is a vacuum line that connects the intake manifold with the charcoal canister that contains the fuel vapors. The purge valve lies within the vacuum line to allow these vapors into the intake manifold at the appropriate time. Older vehicles use vacuum operated purge valves while newer vehicles used electronically operated ones.
