Avoiding Exhaustion (EGR Valve Replacement)

September 22, 2024

No, ERG isn’t the sound a pirate makes.  It’s a part in your vehicle that recirculates exhaust gas to reduce certain gases and pollutants in the atmosphere.  In fact, ERG stands for “Exhaust Gas Recirculation.”

One gas our vehicles may make when they burn fuel is nitric oxide, which can play a big role in creating smog and acid rain.  It’s better for our planet if our vehicles aren’t spewing that into the air.  

One inventive way of reducing it is by taking the exhaust and channeling it back to the vehicle’s air intake system. When it travels through the engine again, its composition is changed, and it comes out cleaner.  It also helps the engine be more efficient.

The EGR valve can fail after a while, and some signs you may notice are the engine is miss firing, it may suddenly lose power or your Check Engine light may come on.  You may also see your fuel economy decrease or hear your engine knock. A bad EGR valve can also make your vehicle fail an emissions test.

There are several different types, including newer ones that are electronically controlled rather than working on vacuum pressure.  They are found in newer gasoline and diesel vehicles. If you notice any of the symptoms of a failing EGR valve, bring your vehicle in so a technician can check to see if your EGR is still up to its “exhausting” job.
