P2759

DTC P2759 Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical (Shift Solenoid Valve SLU)

DESCRIPTION





The amount of current flowing to the solenoid is controlled by the duty ratio* of the ECM output signal. The higher the duty ratio* becomes, the higher the lock-up hydraulic pressure becomes during the lock-up operation.
*: The duty ratio is the ratio of the current ON time (A) to the total of the current ON and OFF times (A + B).
Duty Ratio (%) = A / (A + B) x 100





MONITOR DESCRIPTION
When an open or short in the linear solenoid valve (SLU) circuit is detected, the ECM interprets this as a fault. The ECM turns on the MIL and stores the DTC.
