6. EGR CONTROL
The EGR system is composed of an EGR valve, EGR
solenoid valve, EGR vacuum controller, ECU, etc. The
exhaust gas is recirculated when the EGR solenoid
valve opens to allow the intake manifold pressure to be
transmitted to the EGR valve .
ECU controls the EGR solenoid valve based on the
signals sent from the water temperature sensor, OZ
sensors 1 and 2, crank angle sensor 1, etc .
Refer to C.2-1 Section 8.
