How to Replace an Exhaust Gas Recirculation (EGR) Pressure Feedback Sensor

The exhaust gas recirculation (EGR) system is used to lower combustion temperatures and reduce oxides of nitrogen (NOx) emissions. This is accomplished by directing exhaust gases into the engine combustion chamber to cool the combustion burn.

Some EGR systems use a pressure feedback sensor in the exhaust stream that tells the powertrain control module (PCM) how much exhaust gas is actually flowing. The PCM then uses this information to adjust the EGR vacuum regulator for optimum EGR flow.

The typical symptoms of a failed EGR pressure feedback sensor include stalling, surging, rough idle, increased emissions, and an illuminated check engine light.

Part 1 of 3: Locate the pressure feedback sensor

In order to safely and efficiently replace your EGR pressure feedback sensor you need a couple of basic tools:

Ford Expedition - EGR Pressure Feedback Sensor - Allen, Texas
Joseph (goes by Lee) arrived on time and immediately got to work. Lee showed me the part that he was replacing and explained the functionality of the sensor to me. I added that my truck would make a strange sound during acceleration and Lee advised that the sound was due to the bad / loose hose on the sensor. Once the new sensor was properly installed, the sound went away.
