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:0000000012198152
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:0000000012198153
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:0000000012198154
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.

Fuel Rail Pressure Sensor
INFOID:0000000012198155
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:0000000012198156
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.
Mass Air Flow Sensor (With Intake Air Temperature Sensor 1)
INFOID:0000000012198157
MASS AIR FLOW SENSOR
The mass air flow sensor (MAF sensor) is placed in the stream of
intake air. It measures the intake flow rate by measuring a part of the
entire intake flow. The MAF sensor controls the temperature of the
heater in sensing element to a certain amount.
The temperature distribution around the heater changes according
to the increase in intake air volume. The change is detected by a
thermistor and the air volume data is sent to ECM by the MAF sen-
sor.
INTAKE AIR TEMPERATURE SENSOR 1
The intake air temperature sensor 1 (IAT sensor 1) is built-into the mass air flow sensor. The sensor detects
intake air temperature and transmits a signal to the ECM.
The temperature sensing unit uses a thermistor which is sensitive to the change in temperature.

COMPONENT PARTS
The electric wastegate control actuator operates based on a signal
from ECM and adjusts the turbo charger boost control valve angle
via link rod. The electronic control allows the turbocharger wastegate
control valve to be opened even in non-supercharging regions. This
reduces pumping losses and contributes to the fuel economy. In
charging regions, wastegate valve angles are controlled by the elec-
tronic control with a high degree of accuracy.
TURBOCHARGER BYPASS CONTROL
When an operating signal received from ECM energizes the sole-
noid, the turbocharger bypass control valve opens the valve by suck-
ing in the plunger. The electronically-controlled turbocharger bypass
control valve quickly opens the bypass valve when releasing the
accelerator pedal during driving under supercharge. This reduces
surge sound generated by the back flow of supercharged air to the
compressor fin.
Turbocharger Boost Sensor (With Intake Air Temperature Sensor 2)
INFOID:0000000012198159
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.

Multi-way Control Valve
INFOID:0000000012198160
The multi-way control valve changes flow paths to Heater & EGR
cooler, Oil cooler, and Radiator, according to coolant temperature
and driving conditions.
Engine Coolant Temperature Sensor 1
INFOID:0000000012198161
The engine coolant temperature sensor is used to detect the engine
coolant temperature. The sensor modifies a voltage signal from the
ECM. The modified signal returns to the ECM as the engine coolant
temperature input. The sensor uses a thermistor which is sensitive to
the change in temperature. The electrical resistance of the ther-
mistor decreases as temperature increases.

Engine Coolant Temperature Sensor 2
INFOID:0000000012198162
The engine coolant temperature sensor is used to detect the radia-
tor-outlet water temperature. The sensor modifies a voltage signal
from the ECM. The modified signal returns to the ECM as the radia-
tor-outlet water temperature input. The sensor uses a thermistor
which is sensitive to the change in temperature. The electrical resis-
tance of the thermistor decreases as temperature increases.
<Reference data>
*: These data are reference values and are measured between ECM terminals.
Crankshaft Position Sensor (POS)
INFOID:0000000012198164
The crankshaft position sensor (POS) is located on the oil pan facing
the gear teeth (cogs) of the signal plate. It detects the fluctuation of
the engine revolution.
The sensor consists of a permanent magnet and Hall IC.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation of
the engine revolution.
Camshaft Position Sensor (PHASE)
INFOID:0000000012198165
The camshaft position sensor (PHASE) senses the retraction of
intake camshaft to identify a particular cylinder. The camshaft posi-
tion sensor (PHASE) senses the piston position.
When the crankshaft position sensor (POS) system becomes inoper-
ative, the camshaft position sensor (PHASE) provides various con-
trols of engine parts instead, utilizing timing of cylinder identification
signals.
The sensor consists of a permanent magnet and Hall IC.
When engine is running, the high and low parts of the teeth cause
the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor changes.

Intake Valve Timing Control Solenoid Valve
INFOID:0000000012198166
Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.
Intake Valve Timing Intermediate Lock Control Solenoid Valve
INFOID:0000000012198167
Intake valve timing intermediate lock control solenoid valve is acti-
vated by ON/OFF signals from the ECM.
The intake valve timing intermediate lock control solenoid valve
opens/closes the path of oil pressure acting on the lock key in the
camshaft sprocket (INT).
• When the solenoid valve becomes ON, oil pressure to the lock key
is drained to perform intermediate lock.
• When the solenoid valve becomes OFF, oil pressure is acted on
the lock key to release the intermediate lock.
Exhaust Valve Timing Control Position Sensor
INFOID:0000000012198168
Exhaust valve timing control position sensor detects the protrusion of
the signal plate installed to the exhaust camshaft front end.
This sensor signal is used for sensing a position of the exhaust cam-
shaft.
The sensor consists of a permanent magnet and Hall IC.
When engine is running, the high and low parts of the teeth cause
the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
Exhaust Valve Timing Control Solenoid Valve
INFOID:0000000012198169
