![]() RELATED: 6 Causes of a Knocking or Pinging Car Engine EGR Valve Function If you can, you need to make repairs immediately before any further damage occurs. If you have a check engine light on for a faulty EGR valve, keep an ear out to see if you can hear any knocking. While this won’t always happen if you have a faulty EGR valve, the chances go up dramatically if the valve is stuck closed. Keeping the combustion chamber at a lower temperature prevents the fuel from igniting before it should. One of the lesser-known perks of the EGR valve is that it actually reduces engine knocking. RELATED: Rough Idle Causes & How to Fix it 6. That’s because the EGR valve is typically open then as it recirculates exhaust to lower the overall temperature of the combustion chamber. However, if the EGR valve is stuck closed, you’ll notice more problems while idling after the engine has already warmed up. That’s because usually, the EGR valve starts in the closed position. If your EGR valve is stuck open, then you’re going to get a rough idle, especially when your vehicle hasn’t warmed up yet. You might also notice that your acceleration has become jerky or rough. You’ll notice the problem more at lower speeds if the EGR valve is stuck open and at higher speeds if the EGR valve is stuck closed. Not only does an optimized engine improve fuel economy, but it also improves engine performance. While this might sound like a great symptom, it can damage your engine. One of the advantages of this is that it reduces the combustion chamber’s temperature and improves efficiency.īut when the EGR valve is stuck open, the engine will suck in air that is already measured by the MAF sensor, leading to a lean air-fuel mixture and a reduction in fuel consumption. Your EGR valve works to send the right amount of exhaust back to the combustion chamber. You might notice slightly more smoke when the EGR valve is bad, but this isn’t very common. In fact, if you have a faulty EGR valve, your vehicle will most likely fail an emissions test. Your EGR valve’s primary purpose is to reduce emissions, so you can expect that if it’s not working correctly, your overall emissions will increase. For instance, you might get a check engine light that indicates excessive exhaust chemicals or misfires, even though the problem stems from a faulty EGR valve. While the check engine light will usually point you straight to the EGR valve, it is possible that it might come on due to a symptom instead of a cause. Whether the EGR valve is clogged, stuck open, or stuck closed, you’re going to get a check engine light.
