Engine Control (2TR–FE)System OutlineThis system utilizes an engine ECU and maintains overall control of the engine, transmission and so on. An outline of theengine control is explained Signals(1)Water temp. signal circuitThe water temp. sensor (Engine coolant) detects the engine coolant temp. and has a built–in thermistor with aresistance which varies according to the engine coolant temp. thus the engine coolant temp. is input in the form of acontrol signal into TERMINAL THW of the engine ECU.(2)Intake air temp. signal circuitThe intake air temp. sensor is installed in the air flow meter and detects the intake air temp., which is input as a controlsignal into TERMINAL THA of the engine ECU.(3)RPM signal circuitCamshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position ft position is input as a control signal to TERMINAL G2 of the engine ECU, and engine RPM is input intoTERMINAL NE+.(4)Throttle signal circuitThe throttle body assembly detects the throttle valve opening angle, which is input as a control signal into TERMINALSVTA1 and VTA2 of the engine ECU.(5)Vehicle speed signal circuitThe speed sensor detects the vehicle speed and inputs a control signal to TERMINAL SPD of the engine ECU via thecombination meter.(6)Battery signal circuitVoltage is constantly applied to TERMINAL BATT of the engine ECU. When the ignition SW is turned on, the voltage forengine ECU operation is applied via the MAIN relay to TERMINAL +B of the engine ECU.(7)Starter signal circuitTo confirm whether the engine is cranking, the voltage applied to the starter motor during cranking is detected and thesignal is input into TERMINAL STA of the engine ECU as a control signal.(8)Engine knock signal circuitEngine knocking is detected by knock control sensor (Bank 1) and the signal is input into TERMINAL KNK1 of theengine ECU as a control l System?EFI systemThe EFI system monitors the engine condition through the signals, which are input from each sensor to the engine best fuel injection volume is decided based on this data and the program memorized by the engine ECU, and thecontrol signal is output to TERMINALS #1, #2, #3 and #4 of the engine ECU to operate the fuel injector (Inject the fuel).The EFI system produces control of fuel injection operation by the engine ECU in response to the driving conditions.?ESA systemThe ESA system monitors the engine condition through the signals, which are input to the engine ECU from eachsensor. The best ignition timing is detected according to this data and the memorized data in the engine ECU, and thecontrol signal is output to TERMINALS IGT1, IGT2, IGT3 and IGT4. This signal controls the ignition coil to provide thebest ignition timing for the driving conditions.?Fuel pump control systemThe engine ECU operation outputs to TERMINAL FC and controls the C/OPN relay. Thus controls the fuel pump drivespeed in response to conditions.?Air injection systemAir injection system sends air forcibly into the exhaust pipe with the air pump at the cold start. It activates the catalyst atearly stage to promote to clean up exhaust emission. Air injection control driver runs the air pump and air switchingvalve with signal from the engine sis SystemWith the diagnosis system, when there is a malfunctioning in the engine ECU signal system, the malfunction system isrecorded in the memory. The malfunctioning system can be found by reading the display (Code) of the check engine –Safe SystemWhen a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control basedon the signals from that system, the fail–safe system either controls the system by using data (Standard values) recorded inthe engine ECU memory or else stops the engine.100HIACE (EWD622E)
