DTC P2716 Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT): Description
WARNING: This page is about a different car, the 2008 Toyota Yaris. However, it is still accessible from the selected car via links, so may be relevant.
The throttle pressure that is applied to the primary regulator valve (which modulates the line pressure) causes shift solenoid valve SLT, under electronic control, to precisely modulate and generate the line pressure according to the extent that the accelerator pedal is depressed or the engine power output.
This controls the line pressure and provides smooth shifting characteristics.
Upon receiving a throttle valve opening angle signal, the ECM controls the line pressure by sending a predetermined duty ratio* to the solenoid valve, modulating the line pressure and generating throttle pressure.
*: The duty ratio is the ratio of the current ON time (A) to the total of the current ON and OFF time (A + B). Duty Ratio (%) = A / (A + B) x 100
