TM-64 < SYSTEM DESCRIPTION > [CVT: RE0F11A] COMPONENT PARTS • 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:0000000009019593 • 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-71, "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:0000000009019594 • 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:0000000009019595 • 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:0000000009019596 • 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-71, "TRANSAXLE : Component Description" • The torque converter clutch solenoid valve utilizes a linear solenoid valve [N/L (normal low) type].
