• 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 : Primary Pressure Sensor
INFOID:0000000010245525
• The primary pressure sensor is installed to control valve.
• The primary pressure sensor detects the pressure applied to the primary pulley.
• When pressure is applied to the ceramic device in the primary pressure sensor, the ceramic device is
deformed, resulting in voltage change. TCM evaluates the primary pressure from its voltage change. Voltage
is increased along with pressure increase.
CVT CONTROL SYSTEM : Secondary Pressure Sensor
INFOID:0000000010245526
• 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 metal diaphragm in the secondary pressure sensor, the metal diaphragm 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 : Primary Pressure Solenoid Valve
INFOID:0000000010245527
• The primary pressure solenoid valve is installed to control valve.
• The primary pressure solenoid valve controls the primary reducing valve. For information about the primary
reducing valve, refer to
TM-444, "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 fact that the
force pressing on the valve spool installed inside the coil
increases nearly in proportion to the current. This allows it to pro-
duce 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 : Secondary Pressure Solenoid Valve
INFOID:0000000010245528
• The secondary pressure solenoid valve is installed to control valve.
• The secondary pressure solenoid valve controls the secondary reducing valve. For information about the
secondary reducing valve, refer to
TM-444, "TRANSAXLE : Component Description"
.
• The secondary pressure solenoid valve uses the linear solenoid
valve [N/H (normal high) type].
NOTE:
• The principle of the linear solenoid valve utilizes the fact that the
force pressing on the valve spool installed inside the coil
increases nearly in proportion to the current. This allows it to pro-
duce a fluid pressure that is proportional to this pressing force.

is not energized.
CVT CONTROL SYSTEM : Select Solenoid Valve
INFOID:0000000010245529
• The select solenoid valve is installed to control valve.
• The select solenoid valve adjusts the forward clutch engaging pressure and the reverse brake engaging
pressure. For information about the forward clutch and reverse brake, refer to

CVT CONTROL SYSTEM : Torque Converter Clutch Solenoid Valve
INFOID:0000000010245530
• The torque converter clutch solenoid valve is installed to control valve.
• The torque converter clutch solenoid valve controls the torque converter clutch control valve. For information
about the torque converter clutch control valve, refer to
TM-444, "TRANSAXLE : Component Description"
.
• The torque converter clutch solenoid valve utilizes a linear sole-
noid valve [N/L (normal low) type].
NOTE:
• The principle of the linear solenoid valve utilizes the fact that the
force pressing on the valve spool installed inside the coil
increases nearly in proportion to the current. This allows it to pro-
duce a fluid pressure that is proportional to this pressing force.
• The N/L (normal low) type does not produce hydraulic control
when the coil is not energized.
CVT CONTROL SYSTEM : Line Pressure Solenoid Valve
INFOID:0000000010245531
• The line pressure solenoid valve is installed to control valve.
• The line pressure solenoid valve controls the pressure regulator valve. For information about the pressure
regulator valve, refer to
TM-444, "TRANSAXLE : Component Description"
.
• The line pressure solenoid valve uses the linear solenoid valve [N/
H (normal high) type].
NOTE:
• The principle of the linear solenoid valve utilizes the fact that the

increases nearly in proportion to the current. This allows it to pro-
duce a fluid pressure that is proportional to this pressing force.

is not energized.
CVT CONTROL SYSTEM : G SENSOR
INFOID:0000000010304575
• G sensor detects front/rear G and inclination applied to the vehicle.
• G sensor converts front/rear G and inclination applied to the vehi-
cle to voltage signal. TCM evaluates front/rear G and inclination
angle of the vehicle from the voltage signal.

COMPONENT PARTS
CVT CONTROL SYSTEM : Electric Oil Pump
INFOID:0000000010304576
• It is operated with the signal from TCM during stop/start operation.
Oil pressure required for restart of the engine is obtained instead of
the mechanical oil pump.
• During operation, the status signal (Duty) is sent to TCM.
Electric oil pump status signal characteristics
CVT CONTROL SYSTEM : Electric Oil Pump Relay
INFOID:0000000010304577
• The electric oil pump relay is deactivated when the vehicle speed reaches 11 km/h (7 MPH) or more and
becomes activated when it reaches 6 km/h (4 MPH) or less.
• It is ON with the signal from TCM. It is ready for operation of the electric oil pump by TCM.
CVT CONTROL SYSTEM : Manual Mode Switch
INFOID:0000000010497871
• The manual mode switch
[mode select switch and position
select switch (upshift/downshift)] is installed in the CVT shift selec-
tor assembly.
• The mode select switch detects the position (the main shift gate
side or manual shift gate side) of the selector lever and transmits a
manual mode signal or a not manual mode signal to the combina-
tion meter. Then, the TCM receives a manual mode signal or non-
manual mode signal from the combination meter.
• The position select switch (upshift) detects that the selector lever is
shifted to the upshift side of the manual shift gate and transmits a
manual mode upshift signal to the combination meter. Then, the
TCM receives a manual mode upshift signal from the combination
meter.
• The position select switch (downshift) detects that the selector lever is shifted to the downshift side of the
manual shift gate and transmits a manual mode downshift signal to the combination meter. Then, the TCM
receives a manual mode downshift signal from the combination meter.
CVT CONTROL SYSTEM : Shift Position Indicator
INFOID:0000000010245533
TCM transmits shift position signal to combination meter via CAN communication. The actual shift position is
displayed on combination meter according to the signal.
