EGR Solenoid: Description and Operation
PURPOSE/OPERATION
The EGR control solenoid regulates the amount of vacuum supplied to the EGR valve. The EGR control solenoid is a duty-cycle type solenoid. It
has a valve that opens and closes the vacuum source line to atmosphere many times per second. This allows only a certain amount of ported
vacuum to be applied to the EGR valve, thereby controlling the amount of EGR operation. The ECM opens and closes the negative circuit and the
control relay supplies the positive circuit.
