Pressure Control Solenoid ”D” Electrical
(Shift Solenoid Valve SLT)
CIRCUIT DESCRIPTION
The throttle pressure that is applied to the primary regulator
valve (which modulates line pressure) causes the solenoid
valve SLT, under electronic control, to precisely and minutely
modulate and generate line pressure according to the accelera-
tor pedal effort, or engine power output detected.
This controls the line pressure and provides smooth shifting
characteristics.
Upon receiving the throttle valve opening angle signal, ECM
controls the line pressure by sending a predetermined (*) duty
ratio to the solenoid valve, modulating the line pressure, gener-
ating throttle pressure.
(*) Duty Ratio:
The duty ratio is the ratio of the period of continuity in one cycle.
For example, if ”A” is the period of continuity in one cycle, and
”B” is the period of non
−
continuity, then
DTC No.
