EC-1502 [YD (WITHOUT EURO-OBD)] EGR VOLUME CONTROL SYSTEM EGR VOLUME CONTROL SYSTEM PFP:14710 Description EBS0151B SYSTEM DESCRIPTION *: This signal is sent to the ECM through CAN communication line. This system controls flow rate of EGR led from exhaust manifold to intake manifold. The opening of the EGR ● Engine stopped ● Engine starting ● Low engine coolant temperature ● Excessively high engine coolant temperature ● High engine speed ● Wide open throttle COMPONENT DESCRIPTION The EGR volume control valve uses a step motor to control the flow Sensor Input Signal to ECM ECM Function Actuator Crankshaft position sensor Engine speed EGR volume control EGR volume control valve Vehicle speed sensor* Vehicle speed Engine coolant temperature sensor Engine coolant temperature Ignition switch Start signal Accelerator pedal position sensor Accelerator pedal position Mass air flow sensor Amount of intake air Air conditioner switch* Air conditioner operation SEF908Y SEF411Y |
