EGR Valve: Description and Operation
EGR Valve And Position Sensor
PURPOSE
The Exhaust Gas Recirculation (EGR) valve recirculates a portion of exhaust gas into the intake manifold, lowering combustion chamber
temperatures and reducing Oxides of Nitrogen (NOx) formed during combustion.
OPERATION
The Powertrain Control Module (PCM) regulates the quantity of recirculated exhaust gas proportional to engine load and other operating
conditions. The EGR valve opens and closes in relation to vacuum applied and released by two PCM controlled solenoids.
