Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical
(Shift Solenoid Valve SLU) (P2759)
DESCRIPTION
The amount of current flow to the solenoid is controlled by the duty ratio* of
the ECM output signal. During the lock-up operation, if the duty ratio increases,
the lock-up hydraulic pressure increases.
HINT:
*: The duty ratio is the ratio ...
