EGR stands for exhaust gas recircuilation valve locate on the exhaust monifold. The purpose of EGR valve is an emission componet require to reduce NOx emission. When the engine combustion chamber temperature reach above 2500 F degree, it create NOx and is a pollutant that make smog. EGR valve job is to recircuilate exhaust gas back in to the intake monifold and use it to cool down the combustion chamber temperature. EGR valve are control by vaccum, solenoid, or temp sensor
