The exhaust gas recirculation (EGR) valve allows your vehicle to be more efficient in completely burning your fuel by recirculating a small portion of your exhaust gasses back into the engine's combustion chamber. You'll get better mileage and less noxious emissions when you have this device installed on your car or truck. A common problem that occurs in this device is when the EGR pressure feedback sensor starts to fail, causing it to send wrong data to your EGR valve. This will result in rough idling and poor acceleration so you'll need to replace this sensor right away.
Clean it or replace it?
Most of the time, you simply have to clean your EGR valve and the entire system will work like new again. Since the EGR valve reuses exhaust fumes, the valve could collect a buildup of carbon deposits, which could block it and cause idling and acceleration problems. You can easily take out the EGR valve and clean it with some mild solvent. If this doesn't solve the problem, then you'd better have a qualified mechanic take a look at it for you, or you can use a scan tool to narrow down your EGR valve's problem. No amount of cleaning can fix your EGR valve, especially the EGR pressure feedback sensor sensor, so we strongly advise that you replace it ASAP.
How much do I need to spend?
Don't worry, the EGR Pressure Feedback Sensor is a small and inexpensive device that you could easily install yourself. Most sensors would run somewhere between $50 to $100, and you could easily find OEM replacements from trusted retailers online. You don't need to confuse yourself with special features or added benefits from these sensors, they pretty much work the same way. You just need to make sure that you get one that is made specifically for your vehicle's make and model, and you're good to go. We recommend that you check your vehicle's manual for information regarding the EGR pressure feedback sensor, so you could easily make an informed choice when buying a replacement online.
