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.
Where is the purge solenoid located?
Purge solenoid is located on the front rad support on the left of vehicle when looking at vehicle from the front.
Where is vapor canister?
Usually the vapor canister’s are located on most vehicles on the driver’s side fender.

What does a canister purge valve solenoid do?
Definition A canister purge valve is a solenoid valve controlled by the Power Train Control Module . 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.
How do you replace a purge valve?
Step 1: Go under the rear of your car and locate the purge valve. Step 2: Remove the connecting hose and the screws on the valve. Step 3: Once the screws are out, slide the valve out of the canister and gently try to remove the electrical connector on the valve. Step 4: Install the replacement purge valve.

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.
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 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.
