What Is an EGR Valve? (EGR Valve Service)

October 27, 2025

If you've ever felt your vehicle hesitate, go, then hesitate again, you might think there's something wrong with the transmission.  After all, it's not moving smoothly  down the road.  But there are plenty of malfunctions that can cause those symptoms, one of them being something you may have never heard of: the EGR valve.

EGR stands for Exhaust Gas Recirculation. It's a system that channels small amounts of exhaust back into the engine to cool down the cylinders and reduce polluting gases.  Those include nitrogen oxides that can cause smog. The EGR valve regulates how much of the vehicle's exhaust gas is recirculated. After years and long distances traveled, that valve can get clogged or fail. Sometimes the EGR valve can stick open.  When the EGR valve isn't working properly, your vehicle can start releasing those nitrogen oxides and pollute the air.

The symptoms of a malfunctioning EGR valve include:

  • Engine losing power
  • Engine idling roughly
  • Pinging and knocking sounds in the engine
  • Stalling and hesitation
  • Fuel economy decreasing
  • Check Engine light illuminated

 

Depending on its condition, the EGR valve can be cleaned or it may need to be replaced.  Consult with your service advisor to see what options are recommended to you.

The EGR system is part of your vehicle's pollution and emissions control equipment. If you care about keeping our planet's atmosphere clean, you'll want to make sure it's doing its job—for everyone's benefit.
