System Description
The hydraulic control mechanism consists of the oil pump directly driven by the engine, the hydraulic control valve that controls line pressure and transmission, and the input signal lin
LINE PRESSURE AND SECONDARY PRESSURE CONTROL
Normal Control
Optimize the line pressure and secondary pressure, depending on driving conditions, on the basis of the throttle position, the engine speed, the primary pulley (input) revolution speed, the secondary pulley (output) revolution speed, the brake signal, the transmission range switch signal, the lock-up signal, the voltage, the target gear ratio, the fluid temperature, and the fluid pressure.
Feedback Control
For the normal fluid control and the select fluid control, secondary pressure is detected for feedback control by using a secondary pressure sensor to set a high-precision secondary pressure.

P0506 ISC system
Description
The ECM controls the engine idle speed to a specified level via the fine
adjustment of the air, which is let into
the intake manifold, by operating the electric throttle control actuator. The
operating of the throttle valve is varied
to allow for optimum control of the engine id ...
