In an effort to keep the air we breathe clean, modern vehicles with internal combustion engines are designed to reduce the emissions by recirculating exhaust gas into the engine.  It has a part that controls how much of that gas to put back into the engine, and that’s known as the EGR valve.

EGR stands for exhaust gas recirculation, and when your fails or get blocked up, you might notice a few of telltale signs.  You may find your acceleration is slow or uneven, your vehicle stalls or idles roughly, you notice a knock or ping when you step on the gas or your fuel economy isn’t what it used to be.  

If your vehicle has those symptoms, bring it in so a technician can track down what is causing the problems. It’s important to have your vehicle checked because a bad EGR valve can lead to expensive engine damage if the combustion temperatures get too high.  An overheated engine can cause your head gasket to fail.  Plus, you may damage your vehicle’s valves and cylinders.  A bad EGR valve can also result in damage to your catalytic converter, another expensive item to replace. 

Our technicians can scan your vehicle’s computers for codes, test the EGR valve and inspect its wiring and vacuum lines.  If they determine it’s the EGR valve, they’ll install a new one with a new gasket, reconnect the electrical plugs and vacuum hoses, then check how the system is working by taking your vehicle for a test drive. 

When you’re back on the road, you will know that your emissions will be cleaner, your fuel economy better and your engine should last longer.
