EGR Pressure Feedback Sensor: also known as a pressure feedback sensor, this is a sensor that detects pressure changes in the EGR system. It works together with the EGR valve to regulate the pressure in the EGR system. When the EGR pressure feedback sensor detects that the pressure is too low, it will open the EGR valve to increase the flow, and just the opposite, if it detects that the pressure is too high, it will close the valve.
Symptoms of a faulty EGR pressure sensor: A faulty EGR system can lead to engine performance problems such as unstable idle speed, engine hesitation, and a decrease in overall power and fuel efficiency. Failure of the emission test will cause the vehicle to fail the emission test. Check engine light comes on.
