The EGR vacuum modulator is a component found on some EGR systems. It controls the flow of the EGR system by using a vacuum operated diaphragm to increase or decrease EGR flow. When the vacuum is high, combustion temperatures and airflow are naturally lower so the diaphragm will close and restrict flow, when vacuum is low airflow and combustion temperatures are higher, so EGR flow must be increased.
