A car’s EGR valve is an important part of its emissions system and it plays a crucial role in helping to keep harmful gas emissions at bay. The majority of modern vehicles incorporate EGR valves into their design to help reduce nitrogen oxide (NOx) emissions and meet stringent emission standards.
The EGR valve recycles a portion of the exhaust gas back into the combustion chamber where it combines with fresh intake air to lower the combustion temperature, which helps to reduce the production of oxides of nitrogen. These are one of the most harmful forms of gases for the environment and can be produced when engines have high combustion temperatures.
In order to maintain a healthy engine, it’s essential to keep the valve clean and functioning properly. In the long run, this can improve the efficiency of your vehicle and save you money on fuel costs as a result.
How to Clean Your EGR Valve
To clean your evr valve, it is necessary to remove it from your intake manifold and then disassemble it to expose the internals. This can be a difficult task for the novice mechanic so it is important to have the assistance of a trained professional.
If you can’t access the valve then it may have become clogged and you will need to replace it. To see if this is the case, stick your finger in one of the openings and try to push it. If it doesn’t move then it is probably clogged up with carbon deposits which will need to be removed and replaced.
A faulty EGR valve can cause several problems for your car including poor power, reduced acceleration and fuel economy. It can also increase your emissions which is not a good thing and will have an impact on the environment.
The first sign that your EGR valve is failing is the check engine light coming on. The engine management system will detect a problem with the valve and will put this light on the dashboard.
Other signs of an EGR valve failure include the exhaust smelling like fuel, a rough idle and a decrease in power and acceleration. Some cars will also experience a spike in the amount of NOx emissions.

How to Replace Your EGR Valves
In most cases, replacing the EGR valve is straightforward. The valve is located on the inlet manifold, and usually comes with mounting bolts that should be removed before removal.
There are three types of EGR valves, depending on the make and model of your vehicle. They can be vacuum controlled units, electronic vacuum controlled valves or digital valves.
Vacuum controlled EGR valves use a solenoid to activate the valve. If your valve is vacuum-controlled, use a scan tool to activate the solenoid and look for a positive vacuum at the end of the pipe.
