Component Description
FUNCTIONS WITHIN THE SYSTEM
The control valve motor uses a DC motor to control the EGR flow from the exhaust manifold. The DC motor controls the valve position according to the driving conditions, in accordance with the commands from the ECM.
INDIVIDUAL FUNCTION WITHIN THE SYSTEM
The EGR volume control valve contains the control valve motor and control position sensor.
INDIVIDUAL OPERATION
EGR Volume Control Position Sensor
The control position sensor uses a permanent magnet and semiconductor element to detect the valve shaft angle and transmit a signal to the ECM. In this way, the ECM transmits a signal for controlling the valve position to the DC motor according to the driving conditions.
COMPONENT LOCATION
EGR volume control valve is installed to the exhaust side of cylinder head.
