![]() Usually a problem with the EGR pressure feedback sensor will produce a few symptoms that can alert the driver of a potential problem that should be serviced. When the EGR pressure feedback sensor detects that the pressure is low, it will open up the EGR valve to increase flow, and just the opposite will close the valve if it detects that pressure is too high.Īs the pressure reading detected by the EGR pressure sensor is one of the most important parameters used by the EGR system, if it has any issues it can cause problems with the EGR system, which can lead to engine performance issues, and even increased emissions. It works together with the EGR valve to regulate the pressure of the EGR system. 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. One of these components commonly found on many EGR systems is the EGR pressure feedback sensor. ![]() The EGR system is made up of several components that work together to accomplish this task. ![]() ![]() The EGR system works by recirculating exhaust gases back into the engine in order to lower cylinder temperatures and NOx emissions. Many modern vehicles are equipped with an EGR system to help lower the vehicle’s emissions.
