What does an EGR valve pressure sensor do?
What does an EGR valve pressure sensor do?
The EGR position sensor detects the movement and position of the exhaust gas recirculation (EGR) valve pintle. The EGR pressure sensor detects exhaust gas flow through the EGR passage.
How is the dpfe sensor connected to the EGR valve?
Basically, follow the EGR pipe until you see 2 metal tubes next to each other split off from it, then follow those to the rubber hoses and those hoses to the DPFE sensor. The EGR Actuator is an electric device that allows small amounts of vacuum pressure to pass on to the EGR Valve.
How does the EGR pressure feedback sensor work?
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.
How is the temperature of the EGR valve controlled?
This EGR valve is controlled through an EGR temperature sensor. The sensor collects vital information and, based on this information, the EGR valve determines when to open and close. When the EGR temperature sensor fails, it causes various issues with the EGR system and the situation should be addressed quickly.
What do pressure feedback ( PFE ) sensors do?
PRESSURE FEEDBACK EGR (PFE) SENSORS A complete cross reference from O.E.M. part numbers to Tomco, Inc. part numbers begin on page 296. PRESSURE FEEDBACK EGR (PFE) SENSORS WHAT THEY DO Change exhaust backpressure into an analog voltage signal. This signal is sent to the computer to control EGR flow, ignition timing and the air/fuel ratio.

How does the EGR actuator work in a car?
