Engine Coolant Temperature Sensor

INFOID:0000000012197639

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.

<Reference data>

*: These data are reference values and are measured between ECM terminals.

Crankshaft Position Sensor (POS)

INFOID:0000000012197640

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.

ECM receives the signals as shown in the figure.

COMPONENT PARTS

Camshaft Position Sensor (PHASE)

INFOID:0000000012197641

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.

ECM receives the signals as shown in the figure.

Intake Valve Timing Control Solenoid Valve

INFOID:0000000012197642

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.

Exhaust Valve Timing Control Position Sensor

INFOID:0000000012197643

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.

stops oil pressure flow to fix the exhaust valve angle at the control

position.

Air Fuel Ratio (A/F) Sensor 1

INFOID:0000000012197645

DESCRIPTION

The sensor element of the A/F sensor 1 is composed an electrode

layer, which transports ions. It has a heater in the element.
The sensor is capable of precise measurement = 1, but also in the

lean and rich range. Together with its control electronics, the sensor
outputs a clear, continuous signal throughout a wide range.

The exhaust gas components diffuse through the diffusion layer at

the sensor cell. An electrode layer is applied voltage, and this current

relative oxygen density in lean. Also this current relative hydrocar-

bon density in rich.

Therefore, the A/F sensor 1 is able to indicate air fuel ratio by this

electrode layer of current. In addition, a heater is integrated in the

sensor to ensure the required operating temperature of approxi-

mately 760

°

C (1,400

°

F).

A/F SENSOR 1 HEATER

A/F sensor 1 heater is integrated in the sensor.

The ECM performs ON/OFF duty control of the A/F sensor 1 heater corresponding to the engine operating

condition to keep the temperature of A/F sensor 1 element within the specified range.

COMPONENT PARTS

The heated oxygen sensor 2, after three way catalyst (manifold),

monitors the oxygen level in the exhaust gas.

Even if switching characteristics of the air fuel ratio (A/F) sensor 1

are shifted, the air fuel ratio is controlled to stoichiometric, by the sig-

nal from the heated oxygen sensor 2.

This sensor is made of ceramic zirconia. The zirconia generates volt-

age from approximately 1 V in richer conditions to 0 V in leaner con-

ditions.

Under normal conditions the heated oxygen sensor 2 is not used for

engine control operation.

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 corresponding to the engine speed,

amount of intake air and engine coolant temperature.

Knock Sensor

INFOID:0000000012197647

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

knocking using a piezoelectric element. A knocking vibration from

the cylinder block is sensed as vibrational pressure. This pressure is

converted into a voltage signal and sent to the ECM.

pulse duty signal, cooling fan control module sends cooling fan motor operating voltage to cooling fan motor.

The revolution speed of cooling fan motor is controlled by duty cycle of the voltage.

COOLING FAN MOTOR

Cooling fan motor receives cooling fan motor operating voltage from cooling fan control module. The revolu-

tion speed of cooling fan motor is controlled by duty cycle of the voltage.

EVAP Canister Purge Volume Control Solenoid Valve

INFOID:0000000012197651

The EVAP canister purge volume control solenoid valve uses a ON/

OFF duty to control the flow rate of fuel vapor from the EVAP canis-

ter. The EVAP canister purge volume control solenoid valve is

moved by ON/OFF pulses from the ECM. The longer the ON pulse,

the greater the amount of fuel vapor that will flow through the valve.

EVAP Canister Vent Control Valve

INFOID:0000000012197652

The EVAP canister vent control valve is located on the EVAP canis-

ter and is used to seal the canister vent.

This solenoid valve responds to signals from the ECM. When the

ECM sends an ON signal, the coil in the solenoid valve is energized.

A plunger will then move to seal the canister vent. The ability to seal

the vent is necessary for the on board diagnosis of other evaporative

emission control system components.

This solenoid valve is used only for diagnosis, and usually remains

opened.

When the vent is closed, under normal purge conditions, the evapo-

rative emission control system is depressurized and allows “EVAP

Control System” diagnosis.

EVAP Control System Pressure Sensor

INFOID:0000000012197653

The EVAP control system pressure sensor detects pressure in the

purge line. The sensor output voltage to the ECM increases as pres-

sure increases.

Battery Current Sensor (With Battery Temperature Sensor)

INFOID:0000000012197654

OUTLINE

The power generation voltage variable control enables fuel con-

sumption to be decreased by reducing the engine load which is

caused by the power generation of the generator.

Based on sensor signals, ECM judges whether or not the power

generation voltage variable control is performed. When performing

the power generation voltage variable control, ECM calculates the

target power generation voltage based on the sensor signal. And

ECM sends the calculated value as the power generation command

value to IPDM E/R. For the details of the power generation voltage

variable control, refer to

CHG-8, "POWER GENERATION VOLTAGE

VARIABLE CONTROL SYSTEM : System Description"

.

CAUTION:

Never connect the electrical component or the ground wire directly to the battery terminal. The con-

nection causes the malfunction of the power generation voltage variable control, and then the battery

discharge may occur.

BATTERY CURRENT SENSOR

The battery current sensor is installed to the battery negative cable. The sensor measures the charging/dis-

charging current of the battery.
