Electric Throttle Control ActuatorINFOID:0000000012431279
Electric throttle control actuator consists of throttle control mo
tor, throttle position sensor, etc.
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 valve in response to driving conditions via the throttle control motor.
Engine Coolant Temperature SensorINFOID:0000000012431280
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.

*: These data are reference values and are measured between ECM terminals.
Engine Oil Pressure SensorINFOID:0000000012431281
The engine oil pressure (EOP) sensor is detects engine oil pressure
and transmits a voltage signal to the ECM.
Engine Oil Temperature SensorINFOID:0000000012431282
The engine oil temperature sensor is used to detect the engine oil
temperature. The sensor modifies a voltage signal from the ECM.
The modified signal returns to the ECM as the engine oil tempera-
ture input. The sensor uses a thermistor which is sensitive to the
change in temperature. The electrical resistance of the thermistor
decreases as temperature increases.

Heated Oxygen Sensor 2
INFOID:0000000012431289
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 cont rolled 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 ox ygen sensor 2 is not used for
engine control operation.
Heated Oxygen Sensor 2 HeaterINFOID:0000000012431290
SYSTEM DESCRIPTION
The ECM performs ON/OFF control of the heated oxy gen sensor 2 heater corresponding to the engine speed,
amount of intake air and engine coolant temperature.
OPERATION
Ignition Coil With Power TransistorINFOID:0000000012431291
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/O FF operation induces the proper high voltage in the coil
secondary circuit.
Intake Air Temperature SensorINFOID:0000000012431292
The intake air temperature sensor is built-into mass air flow sensor
(1). 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. Electrical resistance of the thermistor
decreases in response to the temperature rise.

No. Component Description
1. BCM The BCM receives the fan ON and A/C ON signals from the front air control and sends a com-
pressor ON request to the ECM.
2. Fuse Block (J/B) Located in the passenger compartment, behind the left lower IP, the Fuse Block (J/B) con-
tains the front blower motor relay and several fuses required for the air conditioner control
system.
3. Blower relay The blower relay controls the flow of current to fuse 20, 21 and 22 in the Fuse Block (J/B).
The relay is connected directly to ground, and is energized when the ignition switch is in the
ON or START position.
4. Front blower motor The front blower motor varies the speed at which the air flows through the ventilation system.
5. Front blower motor resistor Ground for the blower is supplied through blower resistor and the blower speed switch. As
the switch is moved from position 1 through 4, more current is allowed to flow through the
motor, for a higher speed. This is because less resistors are in the path as the switch is
moved to a higher position. When the switch is on the highest position, all resistors are by-
passed.
6. Thermo control amp. Thermo control amp. is composed of thermistor and amplifier. When the A/C switch signal is
received from the front air control, the thermo control amp. transmits the A/C ON signal to the
BCM according to evaporator fin temperature. When the thermistor detecting temperature of
the air that passes through evaporator is extremely low, the thermo control amp. sends the
A/C OFF signal to BCM, and stops the compressor.
7. Front air control The front air control controls the operation of the A/C and heating system.

• The fluid temperature sensor uses a thermistor, and changes the signal voltage by converting changes in the
CVT fluid temperature to a resistance value. TCM evaluates the CVT fluid temperature from the signal volt-
age value.
CVT CONTROL SYSTEM : Secondary Pressure SensorINFOID:0000000012430998
• The secondary pressure sensor is installed to control valve.
• The secondary pressure sensor detects the pressure applied to the secondary pulley.
• When pressure is applied to the ceramic device in the secondary pressure sensor, the ceramic device is deformed, resulting in voltage change. TCM evaluates the secondary pressure from its voltage change. Volt-
age is increased along with pressure increase.
CVT CONTROL SYSTEM : Primar y Pressure Solenoid ValveINFOID:0000000012430999
• The primary pressure solenoid valve is installed to control valve.
• The primary pressure solenoid valve controls the primary pressure control valve. For information about the
primary pressure control valve, refer to TM-73, "
TRANSAXLE : Component Description".
• The primary pressure solenoid valve uses the linear solenoid valve [N/H (normal high) type].
NOTE:
• The principle of the linear solenoid valve utilizes the fa ct that the force pressing on the valve spool installed
inside the coil increases nearly in proportion to the current . This allows it to produce a fluid pressure that is
proportional to this pressing force.
• The N/H (normal high) produces hydraulic control when the coil is not energized.
CVT CONTROL SYSTEM : Low Brake Solenoid ValveINFOID:0000000012431000
• The low brake solenoid valve is installed to control valve.
• The low brake solenoid valve adjusts the tightening pressure of the low brake.
