It is a common misconception that the EGR valve needs to be replaced. In many cases, it can be cleaned instead to avoid costly replacement. The EGR valve is responsible for regulating exhaust gas temperature and it can get clogged up from carbon deposits from the engine.
The best way to clean your Honda Accord EGR valve is with a spray can of brake cleaner or carburetor cleaner, which will dissolve the deposits. Don’t forget to use gloves and safety glasses before you start cleaning!
What is an EGR Valve?
EGR valves are used in cars to regulate the pressure. Their function is to release exhaust gases into the atmosphere.
EGR valves are used in cars to regulate the pressure. Their function is to release exhaust gases into the atmosphere. They are also known as Exhaust Gas Recirculation Valves, which are vital for regulating the engine’s intake of air and for reducing emissions of hydrocarbons.
Emission Control System and How It Works
The emission control system might be the most important part of your car, as it ensures that the air pollution from the exhaust is reduced to a minimum.
In order to understand how an emission control system works, one has to first understand what happens when a car is running. When you start your engine, it emits hydrocarbons and carbon dioxide into the air. The exhaust gases will mix with the oxygen in the atmosphere and produce ozone and nitrous oxide which can easily cause smog. The emission control systems stop this from happening by trapping these gases before they reach the atmosphere.
The function of an emission control system can be broken down into three categories: oxidizing, catalytic converter and particulate filter. Oxidizing refers to breaking down harmful gases such as hydrocarbons and nitrous
Symptoms of a Dirty EGR Valve
This article will teach you about the symptoms of a dirty or broken EGR valve in your Honda Accord.
The EGR valve is one of the most important parts of your engine because it regulates the amount of exhaust gas that enters the combustion chamber by allowing only a portion of the exhaust gas to be diverted back into your engine.
The symptoms of a dirty or broken EGR valve are rough idle, rough engine, engine stalls, and poor acceleration.
A dirty or broken EGR valve can cause the following symptoms in your Honda Accord:
- The vehicle may need to be constantly idled in order to complete a drive without stalling.
- The vehicle may not be able to start when cold, but will work normally after it has warmed up.
- The vehicle will not idle while at a stop.
- There may be a noticeable lack of power while driving.

How to Clean a Dirty EGR Valve on a Honda Accord
The EGR valve is a critical component of the vehicle’s exhaust system. It lets excess gasses escape from the engine. When it becomes dirty or broken, it might cause major problems to the car, including overheating and fuel consumption. The associated repairs can be expensive, that is why you should try to clean or replace your EGR valve by yourself before turning to a mechanic for help
Luckily, Honda Accord EGR valves are designed so that they can be easily accessed by DIYers. And if you want to learn how to clean your dirty or broken EGR valve on your own accord, then keep reading!
The first step in this process is locating it under the hood of the vehicle. Turn off the engine and remove any nearby hoses and clamps that could interfere with your work.
When working on your car’s engine, it’s important to make sure you do not have power running to the battery. This can be done by unhooking the cables from the battery. This way, if you accidentally short-circuit your car’s electrical system, it will not cause a fire.
Remove the engine cover if your Honda has one and find the EGR valve. The valve location will vary between vehicles. It is toward the front of the engine on the driver’s side for most Hondas. The owner’s manual will have a diagram to help you find the exact location of the EGR valve.
Remove the EGR valve from the engine. In a Honda, the EGR valve will have one electrical connection to the engine and may also have 1 to 2 hoses attached. These connections will likely be held with retainer clips that will just need to be pressed to release the plug. Hoses may be held in place with screws. The valve will also be bolted in with 1 or 2 bolts. Use a socket wrench to take the bolts out and you will be able to slide the EGR valve right out of the engine.
Look for holes in the valve. If there are any holes in the EGR valve or weak places that look as if they are about to become holes, you should replace the valve instead of cleaning it.
The valves of your car’s fuel injector can get clogged with dirt and leaves over time. Carbon cleaners will remove the build-up and ensure that gas is flowing properly. Fill up a container with carbon cleaner, turn the valve upside down on a stable surface, and let it soak in the cleaner for at least 15 minutes.
Use a wire brush to remove any visible deposits left on the EGR valve. After soaking in the cleaner, any deposits should brush right off. Replace the EGR valve. Put it back exactly as you found it, hook the wires and hoses back up and bolt the valve back into place.
Honda Accord EGR Valve cleaning is not a difficult process, It just needs some time and the right tools. The first step is to find the location of your Honda Accord’s EGR valve. It will be right near the engine, close to the firewall, and up high on the driver’s side in most cases.
You may need to remove a few parts in order to get access to it. You should consult your Honda service manual for specific instructions on how you should go about this process since it can vary depending on what year and model you have.
