Egr Vacuum Solenoid

Egr Vacuum Solenoid

When it comes to your car, the engine is the heart and soul of the operation. That’s why it’s important to keep it in good working order. The engine relies on a number of different systems to function properly, and one of those is the EGR (exhaust gas recirculation) system. The EGR system helps to reduce emissions by recirculating a portion of the exhaust gas back into the engine cylinders. This gas is then burned again, which reduces the amount of harmful emissions that are released into the atmosphere.

One of the key components of the EGR system is the EGR vacuum solenoid. This solenoid is responsible for controlling the flow of exhaust gas into the EGR system. If the solenoid fails, it can cause a number of problems, including increased emissions, engine hesitation, and a decrease in fuel efficiency.

What does EGR vacuum solenoid do?

The EGR vacuum solenoid is a device that controls the flow of exhaust gases into the engine. It is usually located in the engine bay, and is connected to the exhaust manifold. The EGR vacuum solenoid is controlled by the engine computer, and allows the engine to “breath” during certain conditions. When the engine is running, the EGR vacuum solenoid will open and close based on the amount of vacuum in the intake manifold. If the vacuum in the intake manifold is low, the EGR vacuum solenoid will open and allow exhaust gases to enter the engine. This will help to cool the engine and reduce emissions.

How much does it cost to replace an EGR solenoid?

An EGR solenoid can cost anywhere from $50-$200. The price will depend on the make and model of your vehicle. If you have a mechanic do the work for you, it will likely cost more than if you do it yourself. The EGR solenoid is located on the engine and is responsible for recirculating exhaust gases. Over time, it can become clogged or damaged and will need to be replaced. Replacing the EGR solenoid is a relatively simple process and can be done with a few tools.

Does the EGR valve affect vacuum?

The EGR valve affects vacuum by allowing exhaust gases to enter the intake manifold. This increases the amount of air that is being drawn into the engine, which in turn increases the amount of vacuum. The EGR valve is controlled by the engine computer and is opened and closed as needed.

Will a faulty EGR damage engine?

Yes, a faulty EGR can damage your engine. The EGR, or exhaust gas recirculation, system recirculates a portion of your exhaust back into the engine to be burned again. This helps to reduce emissions and improve fuel economy. However, if the EGR system is not working properly, it can allow harmful gases to enter the engine, potentially causing damage.

How long does an EGR solenoid last?

The lifespan of an EGR solenoid can vary depending on the make and model of your vehicle, as well as how often you use and maintain your vehicle. However, on average, an EGR solenoid should last between 60,000 and 100,000 miles.

Can car run without EGR?

No, a car cannot run without an EGR. The EGR, or exhaust gas recirculation, system is a vehicle emissions control device that redirects a portion of an engine’s exhaust gas back into the engine cylinders. Mixing the recirculated exhaust gas with the fresh air/fuel mixture reduces the overall oxygen concentration in the cylinders, which lowers the peak combustion temperatures. This, in turn, reduces the formation of NOx emissions.

How do you test a EGR vacuum solenoid?

To test a EGR vacuum solenoid, first locate the solenoid and disconnect the electrical connector. Next, use a vacuum pump to apply vacuum to the solenoid and check for leaks. Finally, reconnect the electrical connector and check for proper operation.

How do you clean a EGR solenoid?

  1. First, disconnect the negative battery terminal to prevent any electrical shorts.
  2. Next, using a wrench or socket, loosen the retaining bolts and remove the EGR solenoid.
  3. Take the solenoid apart and clean all of the parts with a degreaser or brake cleaner. Be sure to blow out all of the passages with compressed air.
  4. Reassemble the solenoid and reinstall it.
  5. Reconnect the negative battery terminal and start the engine to test the solenoid.

What is the most common causes of EGR failure?

The most common cause of EGR failure is due to a build-up of carbon deposits on the EGR valve, resulting in it becoming stuck in the open position. This can be caused by a number of factors, including engine oil contamination, fuel contamination, and a build-up of soot on the valve itself. In some cases, the EGR valve may simply be worn out and need to be replaced.


The Egr Vacuum Solenoid is an important part of your car’s engine, and it is important to keep it in good working order. If you think that your Egr Vacuum Solenoid is not working properly, then you should take it to a mechanic to have it checked out.
