Egr valve how much does it cost




















This leads to improved fuel economy. Newer EGR systems can even reduce temperatures in the combustion chamber by cooling the exhaust gases. The EGR valve is also known as the exhaust gas recirculation valve.

All the exhaust gases of a vehicle are dependent on the EGR valve to manage their flow. Exhaust gases are typically only recirculated in low or medium load cruising scenarios. This means the EGR valve will stay closed at idle and at full throttle, preventing these exhaust gases from entering the combustion chamber. If there is a problem with the EGR valve, then it may not be able to open and close properly. This could increase emissions and reduce fuel economy, which is the opposite of what the EGR system is supposed to do.

You may not necessarily realize this is happening until you notice some of the more obvious symptoms. The Check Engine light will likely illuminate on the dashboard when you have a failing or bad EGR valve.

For example, if the EGR valve does not close all the way or open all the way when it is supposed to, then the computer will detect something is wrong and activate the Check Engine Light. If the valve is open under full throttle, there will be less combustible air in the engine when you need it most. This could cause pinging and light acceleration. Is it dangerous to drive with a bad EGR valve? Yes, it is. When the EGR valve opens, exhaust gases are reintroduced into the combustion chamber to cool it and reduce oxygen consumption.

The temperature at which oxygen is burned is higher than the temperature at which fuel is burned. Open Position: Rough idling and problems with acceleration are the two most common indicators that the EGR valve is stuck open. Prices for a new EGR valve vary for each make and model. There are many contributing factors: the size of the business, its location, and the demand for the service. As with many of the components in your car, the impact driving with a clogged or damaged EGR valve has on its own performance, and other associated parts could lead to more severe damage and even costlier repairs.

The effects a faulty EGR valve has on your engine performance, specifically the rise in temperature, can cause additional damage to the engine if allowed to operate under such circumstances. Driving for long distances with excessive deposits on your cylinder head could lead to irreparable damage. Running a car using high-quality fuel can help limit deposits. They tend to include cleaning additives that keep those sooty carbon build-ups to a minimum. The EGR valve is controlled by your engine management system.

It connects into your exhaust system via a metal tube, feeding the exhaust gases back in through the inlet manifold. The valve is driven by a solenoid on the EGR unit or by a solenoid on the vacuum circuit. Some EGR units include a cooler that lowers the temperature of the gasses before being sent back into the combustion system.
