How to Clean Purge Solenoid Valve

How To Clean Purge Solenoid Valve? [Step By Step Guide]

The tiny valve could develop clogging that needs to be removed to improve its performance.  

How to clean purge solenoid valve? The Purge solenoid valve is an integral part of the vehicle. The purge solenoid valve is connected to the engine. It begins passing the heated air when the engine warms up. Use the air pressure can or water spray to clean the purge solenoid valve.

How to Clean Purge Solenoid Valve?

The primary job of the purge solenoid valve is to control the fuel vapour and do not allow it to escape from the fuel tank. 

The valve is connected to the charcoal canister to the engine, where the combustion occurs. Different types of sensors are attached to it to check the flow and pressure in the machine. 

For example, the “Check Engine” light gets activated when the sensor experience drop in pressure. Fluctuation in the airflow from low to high is registered in the computer system. 

A step-by-step guide to clean the Purge Solenoid valve

Step 1: Use the Sprayer

Get the MAF Cleaner or carb cleaner sprayer. Both come with the liquid formula packed in the tin container.

The sprayer throws the liquid or air with high pressure, allowing the dirt and dust particles trapped inside the valve to come out quickly. It is the easiest way to clean the valve tubes.

Step 2: Use the hand movement

Pull out the valve and hold it in your hand. Cover the two ends of the purge valve with the help of your fingers. Next, shake the purge valve rapidly for a few minutes. It will release the dirt trapped inside and allow it to remove from one of the ends of the value. 

Step 3: Remove the liquid

The trapped vapor inside the valve might have taken the form of liquid. Open both the ends of the valve and allow the liquid to come outside.

Keep repeating the first and second steps until the liquid and dirt particles are removed from the purge valve. 

Step 4: Spray contact cleaner

The contact cleaner comes in a tin size container. The tin contains liquid stored under high pressure. When you spray the liquid in high pressure, the dirt trapped in the purge valve gets removed due to pressure.

Once the dirt is removed, let the valve dry for a while before you connect back to the engine.

If none of the methods works, you have to use a deep cleaning. The technique is a little trickier and needs expert help. 

The purge valve is made of fixed material. Different parts are stick together with the glue. You have to open them carefully without breaking them to clean them. Hardware tools or cutting machines are be needed to separate the cover. 

So if you can handle the procedure carefully, only try the deep cleaning. Otherwise, please leave it to the expert and clean it from the repair center.

How do I know if my purge solenoid is bad?

Non-working purge solenoid would trigger various system errors. The indicators will tell you whether the purge solenoid is working fine or has developed problems. 

These are some of the common issues found when purge solenoid is bad.

Check engine light

The first trigger prompt in the car is the “Check engine light” alert. The engine light will start blinking as soon as there is a problem with the purge solenoid valve. 

High fuel consumption

The fuel consumption goes up when the purge valve malfunctions. Fuel vapors move through the purge valve. When the valve fails, the flow of the vapors gets halted. The steam should escape from the valve and burn in the process. 

But when the purge valve fails, the process stops and causes the engine to burn more fuel to generate the same energy to run the vehicle. You will experience a drop in the performance of the car.

Engine Performance drops

The blockage in the purge valve or broken parts causes the air to leak in the engine at high pressure. The air flows in the combustion chambers, reducing the car engine’s performance. Also, the heat generated from the high-pressure air could lead to many other issues in the engine compartment.

Difficulty in starting the engine

The engine would take time to start. Whenever you experience this issue, it commonly leads to the purge valves problem. The vacuum leak causes stress in the valve, making it difficult for the engine to run smoothly. 

Consequently, the vehicle will take time to start due to unmetered air release from the valve. Additionally, the air-fuel ratio will be affected, making the problem more serious.

Can you fix a purge valve?

Yes. You can fix the purge valve by yourself. The repair is needed if the parts are broken. A purge valve is an inexpensive repair. Most purge valve system prices are between $100 and $150. Get the car repair from the authorized repair center to avoid long-term problems.

Can you clean a purge solenoid valve?

Yes. You can clean the purge solenoid valve easily. It is a small part connected to the engine’s airflow that prevents the hot air from escaping. The purge solenoid valve stops working when there is a blockage inside. 

The dirt particles get stuck in the valve. It may badly affect the performance of the car engine. The cleaning method is directly connected to removing the blockage. Use can easily remove the valve and use the high-pressure liquid or air to move the dirt particles out from the system.

What causes problems with purge valves?

The significant issues with the purge valves are detected when the purge valve is stuck open or closed. The device contains a door system that opens and closes when the vapor passes through the system.

When the system fails, the air passes through the valve quickly or does not pass when the doors are closed. The device has to function properly to avoid engine problems.

How do you clean a vapor canister purge valve?

Use the air blower to remove the trapped particles in the purge valve. The purge valve in the car engine is a small device. It is connected with the tube from both ends.

The device ensures the engine’s vapor is passed through the valve. When the purge valve fails, either the device leaks the vapor in the machine or blocks the flow of the air. In both cases, the purge valve causes the problem.
