EC-950 [YD (WITH EURO-OBD)] ENGINE CONTROL SYSTEM System Chart EBS0137S *1: The input signal is sent to the ECM through CAN communication line. Fuel Injection Control System EBS0137T SYSTEM DESCRIPTION Three types of fuel injection control are provided to accommodate engine operating conditions; normal control, START CONTROL When the ECM receives a start signal from the ignition switch, the Input (Sensor) ECM Function Output (Actuator) ● Accelerator pedal position sensor ● Fuel rail pressure sensor ● Fuel pump temperature sensor ● Engine coolant temperature sensor ● Mass air flow sensor ● Intake air temperature sensor ● Crankshaft position sensor ● Camshaft position sensor ● Turbocharger boost sensor* 3 ● Vehicle speed sensor* 1 ● ESP/TCS/ABS control unit* 1 ● Ignition switch ● Stop lamp switch ● Air conditioner switch* 1 ● Park/neutral position switch ● Battery voltage ● Power steering pressure switch Fuel injection control Fuel injector and Fuel pump Fuel injection timing control Fuel injector and Fuel pump Fuel cut control Fuel injector and Fuel pump Glow control system Glow relay and glow indicator lamp* 2 On board diagnostic system Malfunction indicator (MI)* 2 EGR volume control EGR volume control valve Cooling fan control Cooling fan relay* 2 Turbocharger boost control* 3 Turbocharger boost control solenoid valve* 3 Air conditioning cut control Air conditioner relay* 2 Sensor Input Signal to ECM ECM Function Actuator Engine coolant temperature sensor Engine coolant temperature Fuel injection control Fuel injector Crankshaft position sensor Engine speed Camshaft position sensor Piston position Ignition switch Start signal Fuel rail pressure sensor Fuel rail pressure SEF648S |
