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

an 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:
