ECM
INFOID:0000000012197626
The ECM consists of a microcomputer and connectors for signal
input and output and for power supply. The ECM controls the engine.
Accelerator Pedal Position Sensor
INFOID:0000000012197627
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensor detects the accelera-
tor position and sends a signal to the ECM.
Accelerator pedal position sensor has two sensors. These sensors
are a kind of potentiometers which transform the accelerator pedal
position into output voltage, and emit the voltage signal to the ECM.
In addition, these sensors detect the opening and closing speed of
the accelerator pedal and feed the voltage signals to the ECM. The
ECM judges the current opening angle of the accelerator pedal from
these signals and controls the throttle control motor based on these
signals.
Idle position of the accelerator pedal is determined by the ECM
receiving the signal from the accelerator pedal position sensor. The
ECM uses this signal for the engine operation such as fuel cut.

COMPONENT PARTS
Electric throttle control actuator consists of throttle body, throttle valve, throttle control motor and throttle posi-
tion sensor.
THROTTLE CONTROL MOTOR RELAY
Power supply for the throttle control motor is provided to the ECM via throttle control motor relay. The throttle
control motor relay is ON/OFF controlled by the ECM. When the ignition switch is turned ON, the ECM sends
an ON signal to throttle control motor relay and battery voltage is provided to the ECM. When the ignition
switch is turned OFF, the ECM sends an OFF signal to throttle control motor relay and battery voltage is not
provided to the ECM.
THROTTLE CONTROL MOTOR
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The current opening angle of the throttle valve is detected by the throttle position sensor and it provides feed-
back to the ECM to control the throttle control motor to make the throttle valve opening angle properly in
response to driving condition.
THROTTLE POSITION SENSOR
The throttle position sensor responds to the throttle valve movement.
The throttle position sensor has two sensors. These sensors are a
kind of potentiometers which transform the throttle valve position into
output voltage, and emit the voltage signal to the ECM. In addition,
these sensors detect the opening and closing speed of the throttle
valve and feed the voltage signals to the ECM. The ECM judges the
current opening angle of the throttle valve from these signals and the
ECM controls the throttle control motor to make the throttle valve
opening angle properly in response to driving condition.
Ignition Coil With Power Transistor
INFOID:0000000012197629
The ignition signal from the ECM is sent to and amplified by the
power transistor. The power transistor turns ON and OFF the ignition
coil primary circuit. This ON/OFF operation induces the proper high
voltage in the coil secondary circuit.

Fuel Injector
INFOID:0000000012197630
For the fuel injector, a high pressure fuel injector is used and this
enables a high-pressure fuel injection at a high voltage within a short
time. The ECM is equipped with an injector driver unit and actuates
the fuel injector at a high voltage (approximately 65 V at the maxi-
mum).
High Pressure Fuel Pump
INFOID:0000000012197631
The high pressure fuel pump is activated by the exhaust camshaft.
ECM controls the high pressure fuel pump control solenoid valve built into the high pressure fuel pump and
adjusts the amount of discharge by changing the suction timing of the low pressure fuel.

COMPONENT PARTS
Fuel Rail Pressure Sensor
INFOID:0000000012197632
The fuel rail pressure (FRP) sensor is placed to the fuel rail and
measures fuel pressure in the fuel rail. The sensor transmits voltage
signal to the ECM. As the pressure increases, the voltage rises. The
ECM controls the fuel pressure in the fuel rail by operating high pres-
sure fuel pump. The ECM uses the signal from fuel rail pressure sen-
sor as a feedback signal.
Low Pressure Fuel Pump
INFOID:0000000012197633
The low pressure fuel pump is integrated with a fuel pressure regula-
tor and a fuel filter. This pump is build into the fuel tank.
Fuel Tank Temperature Sensor
INFOID:0000000012197634
The fuel tank temperature sensor is used to detect the fuel tempera-
ture inside the fuel tank. The sensor modifies a voltage signal from
the ECM. The modified signal returns to the ECM as the fuel temper-
ature input. The sensor uses a thermistor which is sensitive to the
change in temperature. The electrical resistance of the thermistor
decreases as temperature increases.
<Reference data>
*: These data are reference values and are measured between ECM terminals.
Fuel Level Sensor
INFOID:0000000012197635
The fuel level sensor is mounted in the fuel level sensor unit.
The sensor detects a fuel level in the fuel tank and transmits a signal to the combination meter. The combina-
tion meter sends the fuel level sensor signal to the ECM via the CAN communication line.
It consists of two parts, one is mechanical float and the other is variable resistor. Fuel level sensor output volt-
age changes depending on the movement of the fuel mechanical float.

Mass Air Flow Sensor (With Intake Air Temperature Sensor 1)
INFOID:0000000012197636
MASS AIR FLOW SENSOR
The mass air flow sensor (1) is placed in the stream of intake air. It
measures the intake flow rate by measuring a part of the entire
intake flow. The mass air flow sensor controls the temperature of the
hot wire to a certain amount. The heat generated by the hot wire is
reduced as the intake air flows around it. The more air, the greater
the heat loss.
Therefore, the electric current supplied to hot wire is changed to
maintain the temperature of the hot wire as air flow increases. The
ECM detects the air flow by means of this current change.
INTAKE AIR TEMPERATURE SENSOR 1
The intake air temperature sensor 1 is built-into mass air flow sensor. The sensor detects intake air tempera-
ture and transmits a signal to the ECM.
The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical
resistance of the thermistor decreases in response to the temperature rise.
<Reference data>

Turbocharger
INFOID:0000000012197637
Turbocharger boost is controlled by adjusting the pressure to the dia-
phragm of the boost control actuator.
TURBOCHARGER BOOST CONTROL SOLENOID VALVE
Turbocharger boost control solenoid valve is ON/OFF duty controlled by ECM.

And it adjusts the pressure in the diaphragm of the boost control
actuator. The longer the turbocharger boost control solenoid valve is
ON, the higher the boost is increased.
Turbocharger Boost Sensor (With Intake Air Temperature Sensor 2)
INFOID:0000000012197638
TURBOCHARGER BOOST SENSOR
The turbocharger boost sensor detects the pressure of the outlet
side of the intercooler. When increasing the pressure, the output
voltage of the sensor to the ECM increases.
INTAKE AIR TEMPERATURE SENSOR 2
The intake air temperature sensor 2 is built-into turbocharger boost sensor. The sensor detects intake air tem-
perature and transmits a signal to the ECM.
The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical
resistance of the thermistor decreases in response to the temperature rise.
