TM-76

< SYSTEM DESCRIPTION >

[CVT: RE0F11A]

COMPONENT PARTS

CVT CONTROL SYSTEM : Primary Speed Sensor

INFOID:0000000009759322

• 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 : Secondary Speed Sensor

INFOID:0000000009759323

• The secondary speed sensor is installed to side cover of transaxle.

• The secondary speed sensor detects secondary pulley speed.

• The secondary 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:0000000009759324

• The output speed sensor is installed to the back side of transaxle

case.

• The output speed sensor detects final gear speed. TCM evaluates

the vehicle speed from the final gear revolution. 

• 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.

COMPONENT PARTS

CVT CONTROL SYSTEM : CVT Fluid Temperature Sensor

INFOID:0000000009759325

• 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 : Secondary Pressure Sensor

INFOID:0000000009759326

• 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 : Primary Pressure Solenoid Valve

INFOID:0000000009759327

• 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-88, "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 : Low Brake Solenoid Valve

INFOID:0000000009759328

• The low brake solenoid valve   is installed to control valve.

• The low brake solenoid valve adjusts the low brake engaging pres-

sure.
