COMPONENT PARTS

CVT CONTROL SYSTEM : Output Speed Sensor

INFOID:0000000009019839

• 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 rev-

olution. 

• The output speed sensor generates the ON-OFF pulse (short waveform) in proportion to the rotating body

speed which is “The higher the rotating body speed is, the faster the change cycle is”. The TCM judges the

rotating speed from the changing cycle of this pulse signal.

CVT CONTROL SYSTEM : CVT Fluid Temperature Sensor

INFOID:0000000009019840

• 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:0000000009019841

• 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:0000000009019842

• 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-70, "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 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 Valve

INFOID:0000000009019843

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

• The low brake solenoid valve adjusts the tightening pressure of the low brake. 

• The low brake solenoid valve uses the linear solenoid 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 produce 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 : High Clutch & Reverse Brake Solenoid Valve

INFOID:0000000009019844

• The high clutch & reverse brake solenoid valve is installed to control valve.

• The high clutch & reverse brake solenoid valve adjusts the tightening pressure of the high clutch and reverse

brake. 

• The high clutch & reverse brake 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 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 : Torque Converter Clutch Solenoid Valve

INFOID:0000000009019845

• 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-70, "TRANSAXLE : Component Description"

.

• The torque converter clutch solenoid valve utilizes a linear solenoid valve [N/L (normal low) type].

CVT CONTROL SYSTEM : Line Pressure Solenoid Valve

INFOID:0000000009019846

• 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-70, "TRANSAXLE : Component Description"

.

CVT CONTROL SYSTEM : G Sensor

INFOID:0000000009019847

• G sensor is installed to floor under instrument lower cover.

• G sensor detects front/rear G and inclination applied to the vehicle. 

• G sensor converts front/rear G and inclination applied to the vehicle to voltage signal. TCM evaluates front/

rear G and inclination angle of the vehicle from the voltage signal. 

CVT CONTROL SYSTEM : Overdrive Control Switch

INFOID:0000000009019848

• The overdrive control switch is installed to the selector lever knob. 

• When the OD OFF indicator lamp on the combination meter is OFF and the overdrive control switch is

pressed, the overdrive is cancelled and the OD OFF indicator lamp is ON.

• When the OD OFF indicator lamp on the combination meter is ON and the overdrive control switch is

pressed, the overdrive is active and the OD OFF indicator lamp is OFF. 

CVT CONTROL SYSTEM : OD OFF Indicator Lamp

INFOID:0000000009019849

DESIGN/PURPOSE

The O/D OFF indicator notifies the driver that the shift control of

transmaxle is in O/D OFF.

BULB CHECK

Approximately 2 seconds after ignition switch ON.
