The exhaust gas recirculation valve, or EGR valve for short, is one of the most important parts of a vehicle’s emissions control system. It recirculates finely metered quantities of exhaust gas into the intake manifold, which helps reduce cylinder temperatures and nitrogen oxide pollutant emissions.
A faulty EGR valve can cause performance issues and increase your emissions, so it’s essential to know how to detect these signs of an EGR valve failure and get it replaced quickly.
Rough idle
This is one of the most common symptoms that you will notice when your EGR valve is failing. It will cause your car to idle roughly when you turn it on and may feel a bit like a misfire or loss of power when you accelerate.
It will also cause your engine to have a very different air-fuel ratio, which can lead to a reduction in power and fuel efficiency.
The EGR valve is a vital component of your car’s exhaust gas recirculation system, which helps to reduce emissions and improve the performance of your engine. It can help to reduce cylinder temperatures and lower emissions of harmful NOx gasses, which can result in reduced carbon dioxide emissions.
Your car’s EGR valve is usually located on the side of your vehicle’s intake manifold but can be found under the hood as well depending on the make and model of your car. It will have a tube connected to it that feeds the exhaust back into the valve for recycling purposes.
You should check your owner’s manual for the exact location of your evr products. This will help you locate the valve and remove it for cleaning purposes.
A clogged or malfunctioning EGR valve can disrupt the air-fuel ratio, which can affect your engine’s performance and increase your emission levels. It can also lead to an increased amount of soot and carbon deposits that build up inside the EGR valve over time, which is why it’s important to keep your EGR valve clean.
Other factors that can cause your EGR valve to fail include improper maintenance, excessive driving and a bad temperature sensor. The EGR valve is supposed to last ten years or more but this can vary from car to car and will depend on your habits, driving conditions and how much you use your vehicle.
In the event that your EGR valve fails, you’ll likely be able to get it replaced by a mechanic at your local NAPA AUTO PARTS store. The replacement cost will vary but most of the time it’s less expensive than a repair, which is why you should consider getting it replaced soon if you suspect that your EGR valve is failing.
