P1760 - Linear Solenoid For Line Pressure Control Circuit Malfunction (Shift Solenoid SLT)

CIRCUIT DESCRIPTION

DTC Detecting Condition:

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 accelerator pedal effort, or engine power output detected.
This reduces the function of 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, and generating throttle pressure.




Reference:
Refer to the chart for the wave form between terminals SLT+ and SLT- during engine idling.
