[CVT: RE0F10G]
COMPONENT PARTS
CVT CONTROL SYSTEM : Input Speed Sensor
INFOID:0000000010622710
• The input speed sensor is installed to the front side of transaxle
case.
• The input speed sensor detects input shaft speed.
• The input speed sensor generates an ON-OFF pulse signal according to the rotating body speed. TCM
judges the rotating body speed from the pulse signal.
CVT CONTROL SYSTEM : CVT Fluid Temperature Sensor
INFOID:0000000010622711
• The CVT fluid temperature sensor is installed to control valve.
• The CVT fluid temperature sensor detects CVT fluid temperature in oil pan.
• 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:0000000010622712
• 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:0000000010622713
• 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:0000000010622714
• 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-486, "TRANSAXLE : Component Description"
.

COMPONENT PARTS
• 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:0000000010622715
• 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-486, "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.
• The N/H (normal high) produces hydraulic control when the coil
is not energized.
CVT CONTROL SYSTEM : Select Solenoid Valve
INFOID:0000000010622716
• 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
• The select solenoid valve uses the linear solenoid valve [N/H (nor-
mal 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) type produces hydraulic control when the
coil is not energized.
CVT CONTROL SYSTEM : Torque Converter Clutch Solenoid Valve
INFOID:0000000010622717
• 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-486, "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:0000000010622718
• 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-486, "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
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 : G Sensor
INFOID:0000000010632036
• 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.
CVT CONTROL SYSTEM : Electric Oil Pump
INFOID:0000000010632037
• Electric oil pump
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.
