What does EGR pressure feedback sensor do?
The EGR pressure feedback sensor, also known as the delta pressure feedback sensor, is a sensor that detects the pressure changes in the EGR system. It works together with the EGR valve to regulate the pressure of the EGR system.
How do I know if my EGR pressure sensor is bad?
EGR valve symptoms can vary, however, the most common symptoms of a faulty EGR valve are explored below:
- Your engine has a rough idle.
- Your car has poor performance.
- You have increased fuel consumption.
- Your car frequently stalls when idling.
- You can smell fuel.
- Your engine management light stays on.
Where is the EGR pressure feedback sensor?
The EGR pressure feedback sensor is generally found mounted somewhere on the engine or to the firewall.
How long does an EGR sensor last?
An EGR valve may last 100,000 miles if the part is designed well, or it may last only 30,000 miles. Occasionally a part is faulty and requires replacing, but this is often covered under warranty depending on the age of the vehicle.
What happens if EGR is stuck closed?
If the EGR system is clogged up, or the valve is stuck closed, the combustion temperature increases. This may cause pinging (detonation), as well as surging on light acceleration.
What is a EGR pressure feedback hose?
The exhaust gas recirculation (EGR) pressure feedback hoses connect the DPFE sensor to the vehicle’s EGR valve between the intake and exhaust manifolds. Over time, heat, pressure, and emission gases traveling through the hoses will eventually cause them to harden, crack, and leak.
Will a new EGR valve improve performance?
An EGR system which is operating properly can improve the efficiency of an engine. Take care of your EGR valve and system, and you can help reduce the wear and tear on your vehicle. Allow the valve to become clogged, and you can accelerate that wear and tear and affect the performance of your car.
