What are the Symptoms of a Failing EGR Valve?

The exhaust gas recirculation valve, or EGR valve is part of the exhaust system and is designed to circulate the gases back into the vehicle's intake to reduce temperatures and emissions. This valve can have issues and it can cause problems to the EGR system as a whole. You will want to be able to recognize when the valve is failing so you can get it replaced. Here are some symptoms to watch for:

The Engine Isn't Performing Well

If you notice that your engine is hesitating, having trouble starting, or performing oddly in other ways, it could be because of this one little valve. Any time the engine changes, for the worse, you want to have the vehicle inspected to see what's going on.

Rough Idling

If the engine is idling in a rough manner when you are at a stoplight, you may be able to diagnose the issue as a bad EGR valve. This is one of the most common symptoms of the problem and you might also smell fuel when you are sitting there, idling.

A Knocking Sound

You will want to listen carefully to your vehicle and if you hear a pinging or knocking sound when you try to speed up, it could be the valve that isn't causing the air to fuel mixture to be correct. You want to ensure this issue goes away quickly as it will only get louder and make things worse.

Check Engine Light

While the engine is one big part, it is made up of lots of other smaller parts, one of which is this EGR system. If the valve goes bad, it could cause the check engine light to pop on. You never want to ignore this light as the longer you drive with it on, the more likely you are doing damage to other, more serious parts of the engine.
