system utilizes a microcomputer and maintains overall control of the engine, transmission etc An outline of the engine control is given here INPUT SIGNALS (1) Engine coolant temp signal circuit The engine coolant temp sensor detects the engine coolant temp and has a built–in thermister with a resistance, which varies according to the engine coolant temp The engine coolant temp is input into TERMINAL THW of the engine control module as a control signal (2) Intake air temp signal circuit The intake air temp sensor is installed in the mass air flow meter and detects the intake air temp which is input as a control signal to TERMINAL THA of the engine control module (3) Oxygen density signal circuit The oxygen density in the exhaust emission is detected by the heated oxygen sensors and input as a control signal to TERMINALS OX1A, OX2A, OX1B and OX2B of the engine control module (4) RPM signal circuit Camshaft position is detected by the camshaft position sensor and its signal is input to TERMINAL G2 of the engine control module as a control signal Also,engine RPM is detected by the crankshaft position sensor and is input as a control signal to TERMINAL NE+ (5) Throttle position signal circuit The throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINAL VTA of the engine control module (6) Vehicle speed circuit The vehicle speed sensor (Electronically controlled transmission) detects the vehicle speed and inputs a control signal to TERMINAL SP2+ of the engine control module (7) Battery signal circuit Voltage is constantly applied to TERMINAL BATT of the engine control module With the ignition SW turned on, the voltage for engine control module start–up power supply is applied to TERMINALS +B, B2 of the engine control module via the EFI relay The current flowing through the IGN fuse flows to TERMINAL IGSW of the engine control module Voltage is constantly applied to TERMINAL BM of the engine control module (8) Intake air volume signal circuit Intake air volume is detected by the mass air flow meter and the signal is input to TERMINAL VG of the engine control module as a control signal (9) Stop light SW signal circuit The stop light SW is used to detect whether the vehicle is braking or not and the signal is input into TERMINAL STP of the engine control module as a control signal (10) Starter signal circuit To confirm whether the engine is cranking, the voltage is applied to the starter motor during cranking is detected and the signal is input into TERMINAL STA of the engine control module as a control signal (11) Engine knock signal circuit Engine knocking is detected by knock sensors and the signal is input into TERMINALS KNK1 and KNK2 as a control signal 97 2004 LEXUS GS 430 / GS 300 (EWD544U) ENGINE CONTROL (2JZ–GE) CONTROL SYSTEM ∗ SFI system The SFI system monitors the engine condition through the signals input from each sensor (Input signals from (1) to (11) etc.) to the engine control module And the control signal is output to TERMINALS #10, #20, #30, #40, #50 and #60 of the engine control module to operate the injector (Inject the fuel) The SFI system controls the fuel injection operation by the engine control module in response to the driving conditions ∗ ESA system The ESA system monitors the engine condition through the signals input to the engine control module from each sensor (Input signals from (1), (2), (4), to (11) etc.) The best ignition timing is decided according to this data and the memorized data in the engine control module and the control signal is output to TERMINALS IGT, IGT2, IGT3 This signal controls the igniter to provide the best ignition timing for the driving conditions ∗ Heated oxygen sensor heater control system The heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp of exhaust emissions is low), and warms up the oxygen sensors to improve detection performance of the sensors The engine control module evaluates the signals from each sensor (Input signals from (1), (2), (4), (7), to (9) etc.), and outputs current to TERMINALS HT1A, HT2A, HT1B and HT2B to control the heater ∗ Fuel pump control system The engine control module outputs current to TERMINAL FPC and controls the fuel pump control ECU and fuel pump drive speed in response to the driving conditions ∗ ACIS ACIS includes a valve in the bulkhead separating the surge tank into two parts This valve is opened and closed in accordance with the driving conditions to control the intake manifold length in two stages for increased engine output in all ranges from low to high speeds ∗ ETCS–i The ETCS–i controls the engine output at its optimal level corresponding to the opening of the accel pedal under all driving conditions ∗ MPX The MPX communicates with the combination meter, A/C control assembly, as well as body ECU of the multiplex communication system DIAGNOSIS SYSTEM With the diagnosis system, when there is a malfunction in the engine control module signal system, the malfunctioning system is recorded in the memory The malfunctioning system can be found by reading the code displayed by the malfunction indicator lamp FAIL–SAFE SYSTEM When a malfunction has occurred in any system, if there is a possibility of engine trouble being caused by continued control based on the signals from that system, the fail–safe system either controls the system by using data (Standard values) recorded in the engine control module memory or else stops the engine 98 2004 LEXUS GS 430
