EGR Control System
In this
EGR control system, the
EGR valve signals are controlled by a duty solenoid which in turn is controlled by the ECM. A vacuum regulator is installed on the vacuum line, which functions to limit vacuum variation and keep up constant pressure, thus maintaining good control. In addition, a vacuum tank is used to provide constant vacuum.
