COMPONENT PARTS
• 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 SensorINFOID:0000000009464184
• The output speed sensor is installed to back side of transaxle.
• The output speed sensor detects final gear speed.
• 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, t he faster the change cycle is”. The TCM judges the
rotating speed from the changing cycle of this pulse signal.
CVT CONTROL SYSTEM : Input Speed SensorINFOID:0000000009464185

COMPONENT PARTS
• 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.

• 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 ValveINFOID:0000000009464189
• The primary pressure solenoid valve is installed to control valve.
• The primary pressure solenoid valve controls the prim ary reducing valve. For information about the primary
reducing valve, refer to TM-229, "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 fa ct 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 : Secondary Pressure Solenoid ValveINFOID:0000000009464190
