< SYSTEM DESCRIPTION >
[CVT: RE0F10D]
COMPONENT PARTS
*: These components are included in control valve assembly.
CVT CONTROL SYSTEM : TCM
INFOID:0000000010622425
• The TCM consists of a microcomputer and connectors for signal
input and output and for power supply.
• The vehicle driving status is judged based on the signals from the
sensors, switches, and other control units, and the optimal tran-
saxle control is performed.
• For TCM control items, refer to
.
CVT CONTROL SYSTEM : Transmission Range Switch
INFOID:0000000010622426
• The transmission range switch is installed to upper part of tran-
saxle case.
• The transmission range switch detects the selector lever position.
CVT CONTROL SYSTEM : Primary Speed Sensor
INFOID:0000000010622427
• The primary speed sensor is installed to side cover of transaxle.
• The primary speed sensor detects primary pulley speed.

• The primary 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 : Output Speed Sensor
INFOID:0000000010622428
• The output speed sensor is installed to back side of transaxle.
• The output speed sensor detects final gear speed.
• The output 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 : Input Speed Sensor
INFOID:0000000010622429
• 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:0000000010622430
• 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:0000000010622431
• 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:0000000010622432
• The secondary pressure sensor is installed to control valve.
• The secondary pressure sensor detects the pressure applied to the secondary pulley.
