COMPONENT PARTS

EVAP Canister Purge Volume Control Solenoid Valve

INFOID:0000000010379012

The EVAP canister purge volume control solenoid valve controls the flow rate of fuel vapor from the EVAP
canister.

Exhaust Valve Timing Control Position Sensor

INFOID:0000000010471157

Exhaust valve timing control position sensor detects the protrusion of the signal plate installed to the exhaust
camshaft. 
This sensor signal is used for sensing a position of the exhaust camshaft.

Exhaust Valve Timing Control Solenoid Valve

INFOID:0000000010471149

Exhaust valve timing control solenoid valve is controlled by ECM.

Fuel Injector

INFOID:0000000010379013

For the fuel injector, a high pressure fuel injector is used and this enables a high-pressure fuel injection within
a short time.

Fuel Rail Pressure Sensor

INFOID:0000000010471147

The fuel rail pressure (FRP) sensor is placed to the fuel rail. It measures the fuel pressure in the fuel rail. The
sensor sends voltage signal to the ECM. As the pressure increases, the voltage rises. ECM operates fuel flow
actuator according to feedback signal from fuel rail pressure sensor, and controls fuel pressure inside fuel rail.

Heated Oxygen Sensor 1

INFOID:0000000010379015

DESCRIPTION

The heated oxygen sensor 1 is placed into the exhaust manifold. It detects the amount of oxygen in the
exhaust gas compared to the outside air. The heated oxygen sensor 1 signal is sent to the ECM. The ECM
adjusts the injection pulse duration to achieve the ideal air-fuel ratio.

HEATED OXYGEN SENSOR 1 HEATER

Heated oxygen sensor 1 heater is integrated in the sensor.
The ECM performs ON/OFF control of the heated oxygen sensor 1 heater.

Heated Oxygen Sensor 2

INFOID:0000000010379016

DESCRIPTION

The heated oxygen sensor 2, after three way catalyst (manifold), monitors the oxygen level in the exhaust gas.

HEATED OXYGEN SENSOR 2 HEATER

Heated oxygen sensor 2 heater is integrated in the sensor.
The ECM performs ON/OFF control of the heated oxygen sensor 2 heater.

High Pressure Fuel Pump

INFOID:0000000010471146

High pressure fuel pump pumps fuel to the fuel rail.

Hood Switch

INFOID:0000000010471143

Hood switch is located around radiator core support. Hood switch detects open/close condition of hood and
input the hood switch signal to IPDM E/R.

Ignition Coil

INFOID:0000000010379017

ECM turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high volt-
age in the coil secondary circuit.

Intake Air Temperature Sensor

INFOID:0000000010379018

The intake air temperature sensor detects intake air temperature and transmits a signal to the ECM.

Intake Manifold Pressure Sensor

INFOID:0000000010379021

The intake manifold pressure sensor is installed to the intake manifold. Detects intake manifold pressure, and
transmits a voltage signal to the ECM.

Intake Valve Timing Control Solenoid Valve

INFOID:0000000010471150

Intake valve timing control solenoid valve is controlled by ECM.

Knock Sensor

INFOID:0000000010379019

The knock sensor is attached to the cylinder block. It senses engine knocking.

Fuel Pump

INFOID:0000000010379014

Fuel pump is installed in the fuel tank and pumps fuel to the high puressure fuel pump.

Malfunction Indicator Lamp

INFOID:0000000010379020

Malfunction Indicator lamp (MIL) is located on the combination
meter.
MIL will illuminate when the ignition switch is turned ON without the
engine running. This is a bulb check.
When the engine is started, MIL should turn OFF. If the MIL remains
illuminated, the on board diagnostic system has detected an engine
system malfunction.

Reverse/Neutral Position Switch

INFOID:0000000010471177

Reverse/Neutral position switch detects gear position is reverse/neutral.

Refrigerant Pressure Sensor

INFOID:0000000010379022

The refrigerant pressure sensor is installed at the condenser of the air conditioner system. The sensor uses an
electrostatic volume pressure transducer to convert refrigerant pressure to voltage. The voltage signal is sent
to ECM, and ECM controls cooling fan system.

Stop Lamp Switch

INFOID:0000000010379023

Stop lamp switch is installed to brake pedal bracket.
Brake switch signal is applied to the ECM through the stop lamp switch when the brake pedal is depressed.
This signal is used mainly to decrease the engine speed when the vehicle is being driven.

Stop/Start Indicator Lamp

INFOID:0000000010471144

The stop/start indicator lamp is located on the combination meter.
The stop/start indicator lamp turns ON when the stop/start system is
operating.
When a malfunction is detected in the stop/start system, the stop/
start indicator lamp blinks at a slow speed to alert the driver to the
malfunction. When a driver

s operation is judged as dangerous one

during stop/start system operation, the stop/start indicator lamp
blinks at a high speed.

*: Engine is stalled after alert for 1.5 seconds.

Stop/Start OFF Switch

INFOID:0000000010471145

The stop/start OFF switch is mounted on the switch panel of the
driver side lower instrument panel. When the stop/start OFF switch
is pressed, the indicator lump turns ON and the stop/start system
can be deactivated.

Thermostat Heater Control Solenoid Valve

INFOID:0000000010471165

The thermostat heater control solenoid valve regulates the coolant temperature within normal operation tem-
perature.

Turbocharger wastegate control solenoid valve

INFOID:0000000010436298

Turbocharger wastegate control solenoid valve actuates the wastegate diaphragm. An output pressure of the
valve is between ambient pressure and boost pressure. When this valve is driven, the wastegate valve closes.

Turbocharger Boost Sensor

INFOID:0000000010436212

Turbocharger boost sensor is used to get the boost pressure information in order to adapt the intake manifold
pressure to the set-point.

Turbocharger bypass valve control solenoid valve

INFOID:0000000010436213

Turbocharger bypass valve control solenoid valve is used to release high pressure air upstream the compres-
sor in order to decrease pressure between the turbocharger outlet and throttle valve. Accordingly, this opera-
tion prevents the decrease in turbine speed and improves the response time of charging when shifting gears.
