Connect scantool to Data Link Cable (DLC)
Warm engine up to normal operating temperature.
Turn "OFF" electrical devices and A/C.
Monitor "MAFS " parameter on the scantool.
Specification : Without EGR actuator operation : 480mg/st ± 50 mg/st
With EGR actuator operation : 350ms/st ± 50 mg/st
※ EGR actuator operates as decelerating after rapid acceleration when idle EGR does not operate, EGR actuator operating duty decreases as time goes by.
This controlling process lasts for about 90 sec. and EGR actuator turns "OFF" (duty 5.0% ) after 90 sec.
