How To Clean Purge Solenoid Valve

Among all the components of a car, the engine is of the utmost importance. The engine is the engine that propels the car forward, and the engine is the engine that uses up the fuel. It is common for the engine of your car to become clogged with dirt and grime over the course of time. The result can be a decrease in the performance of the car and a decrease in its fuel efficiency. If it is not dealt with properly, it can even result in the failure of the engine. Keeping your purge solenoid valve clean is one of the most important things you can do to keep your engine running smoothly. From the engine to the exhaust system, this valve is responsible for controlling the flow of fuel vapor from the engine.

In the event that the purge solenoid valve becomes clogged, a build-up of pressure in the engine can result, which, in turn, can decrease the performance of the engine as well as its fuel economy. In some cases, it can even lead to the engine stalling out. Whenever possible, ensure that your purge solenoid valve is being cleaned by a qualified mechanic on a regular basis in order to avoid these problems.

The purpose of this article is to explain how to clean a purge solenoid valve if you want to know how to do so. To begin with, let me explain a little bit about what a purge valve on a car is and what a step-by-step guide I can give you to clean it.

How to Clean Purge Solenoid Valve

In an Evaporative Emission Control system, the purge solenoid valve is a part. Fuel vapors are impossible to escape from the fuel tank due to the fact that it prevents them from escaping. The valve opens gradually in a modern car as the engine warms up during the course of running the engine. As a result, some vapors can be moved from the charcoal canister to the engine where they are burned, allowing for some vapour to be emitted. In spite of this, various sensors are used to monitor the flow of the fluid. It is for this reason that the computer illuminates the “Check Engine” light when there is more or less flow than what should be produced under the right circumstances.

This is how you clean the purge solenoid:

Step:1

Start by spraying the inside of both the purge solenoid valve tubes with lots of carb cleaner or MAF cleaner.

Step:2

It is important that you cover the ends of the purge valve with your fingers and shake it thoroughly with your fingers. Make sure they are covered until all the dirt has been washed away.

Step:3

Let the liquid flow out of the ends by uncovering them. Once the dirt, debris, and charcoal have been removed, the next step is to repeat the first and second steps above until the liquid comes out clean from the bottom.

Step:4

In addition to the valve connector, spray some contact cleaner inside the car switch as well. Once everything has dried, you can move on to the next step.

DEEP CLEANING

There should be an opening of the purge valve when it is supposed to be closed. In spite of this, you may be able to open it by using a screwdriver with a flat blade or maybe even a knife if you have one. Listed below are some instructions on how you can deep clean the solenoid valve of your purge system.

Step:1

In most cases, purge valves appear to be composed of two halves that are glued together. By using a flat-blade screwdriver, it will be easy for you to separate the two. Using your hands, separate the case from the box as much as you can before applying any glue.

Step:2

As soon as the purge valve is split into two parts, one part will have the purge valve components, and the other will be empty. Due to this, the case of the valve body should be removed from the valve.

Step:3

Inspect the rubber parts and O-rings in the interior of the vehicle. Keep them lubricated by using silicone grease as a lubricant. When reassembling the valve, it is important to make sure the O-ring is sealed properly to prevent the possibility of a leak from occurring.

Step:4

It should be sprayed with MAF or Carb Clean and then rubbed with a dry cloth to deep clean the orifices of the solenoid using a dry cloth.

Step:5

Please make sure that you put everything back in the correct order once you have cleaned the purge valve’s interior. In the event that you are not careful, you may damage the solenoid valve on your purge system. It is recommended that you reseal the case just like it was when new by using a strong glue like epoxy glue. However, it is very important to keep in mind that using such a glue means that it will be impossible in the future to open the case for deep cleaning again.

Can you fix a purge valve?

The good news is that you can fix a purge valve yourself, and the best thing about it is that you will not have to pay too much to fix it. When you know that it is the purge valve that is the problem, you will have less stress and you will not have to worry as much about the check engine light. Some mechanics refer to it as a canister purge valve, because it is a simple problem that sometimes occurs with canisters.

There is no big deal if your purge valve breaks, and your car won’t smoke or develop visible problems as a result of its failure, but it can cause damage in some internal areas as a result of its failure. Despite the fact that it is a sensitive part of your vehicle and requires basic skills, you should be able to replace the purge valve on your own, though it is always advisable to have experts do it for you if you can.

How do I know if my purge solenoid is bad?

Check Engine Light

Check engine light is one of the first signs that you should check if you suspect a problem. In order to detect a problem within the purge solenoid valve, the vehicle’s computer will illuminate this light. This is why you should get the help of a qualified mechanic in order to diagnose the problem because it may be caused by other problems affecting the engine as well. The cost of engine repairs may end up being much higher if a small mistake is made.

High fuel consumption

It is necessary to burn the fuel vapors escaping from the purge valve when the valve malfunctions due to the fact that the fuel vapors must escape. In order to provide you with sufficient power, your vehicle will have to consume more fuel in order to achieve this.

Engine performance issues

There is a risk of leakage when the purge valve is stuck open. It is important to keep in mind that this causes the air to flow extremely high in the combustion chamber, causing various problems with the engine’s performance and causing different types of problems.

Difficulty starting

A common sign of a purge valve malfunction is difficult starting of the engine. There is a vacuum leak that occurs in the canister purge solenoid due to a problem within the solenoid, which is caused by the vacuum leaking. This leads to a decrease in the starting speed of the vehicle due to the unmetered air that finds its way into the engine as a result of the vacuum leak. In this case, it affects the air-fuel ratio, which will increase the difficulty of starting the engine once it has been started.

What causes problems in the purge valves?

It has been observed that holes or blockages in the supply lines of purge valves can cause problems in the purge valves. In this condition, the solenoid valves will not perform properly and will fail to function. As such, the valves will remain closed on account of the failure to function. It is also possible, however, for the valves to remain closed if the solenoid’s electrical portion fails.

Is it safe to drive with a bad purge valve?

There is no need to worry even if your car has been diagnosed as having a bad purge valve because you can still drive it. You will, however, run the risk of further damaging the EVAP system as well as other parts of the vehicle by doing this. There is no danger to your life, but you are putting your car in danger and you may end up paying a lot of money for it.

There are a variety of factors that may prevent you from being able to repair your own home, such as a lack of proper tools, time, skills, or a safe environment to work in. It is recommended that you seek professional help from a mechanic if you wish to get quality repairs done.

THE IMPORTANT PARTS OF A PURGE VALVE

There are three main parts that make up a car purge valve:

  • Casing: In order to protect the plunger and the solenoid inside the casing, it is made of plastic.

  • Electrical Plug: The electrical plug serves a dual purpose, in that it supplies power to the solenoid and it also activates or deactivates the purge valve when in use.

  • Internal Solenoid and Plunger: The purge valve is opened and closed by the internal solenoid and plunger, which can be found inside the valve housing.

THREE MOST COMMON PURGE VALVE PROBLEMS REVEALED

There are three main problems with purge solenoid valves, which can cause them to malfunction:

  • As a result of cracks in the casing, as well as the pipes that supply and drain it, the casing could leak. A crack in the casing of the valve will cause the liquid or gas that is being purged to escape.

  • There might be a problem with the coil. This will lead to the valve not being able to open or close if this is the case, since no current will be generated.

  • In order for the valve to operate properly, debris or carbon build-up inside of the valve needs to be removed.

This can result in the valve not functioning as it should due to all three of these problems.

Step-By-Step Guide To Clean The Purge Valve Without Opening

A quick and easy way to help improve your car’s performance is to clean the purge solenoid valve on your car. The valve doesn’t need to be opened in order for it to be cleaned – actually, you might not even have to remove it from the car in order to clean it! In this guide, you will learn how to clean your purge solenoid valve easy and quickly by following the instructions listed below.

STEP 1: USE THE SPRAYER

In order to clean the tubes of the purge solenoid valve, you should use a carb cleaning spray or a spray meant for cleaning Mass Air Flow Sensors.

STEP 2: USE THE HAND MOVEMENT

Put your fingers over the ends of the tubes and shake them for a few seconds. Let the clearer do the work for a few minutes and then leave it like that for a few minutes.

STEP 3: REMOVE THE LIQUID

As soon as the cleaner has soaked into your fingers for some time, remove them and allow it to drain out. You will be able to notice that the color of the cleaning liquid has darkened due to the fact that it has now been mixed with all the dirt and debris that has accumulated on the valve tubes. Continue to drain out the liquid again a few more times until you notice the liquid no longer appears dark when you repeat the second step.

STEP 4: SPRAY CONTACT CLEANER

The purge solenoid valve’s connector is also connected to the car switch, so it is important that you spray a good contact cleaner on these to prevent contamination from occurring.

STEP 5: LET IT DRY

Make sure that everything is completely dry before starting the car engine.
