DTC P2759 TORQUE CONVERTER CLUTCH PRESSURE CONTROL SOLENOID CONTROL CIRCUIT ELECTRICAL (SHIFT SOLENOID VALVE SLU)CIRCUIT DESCRIPTION
DTC Detection Conditions:
The current flow 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 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
Duty Ratio = A / (A + B) x 100(%).
MONITOR DESCRIPTION
Monitor Strategy:
Typical Enabling Conditions:
Typical Malfunction Thresholds:
When an open or short is detected in the shift solenoid valve (SLU) circuit, the ECM determines that there is a malfunction. The ECM turns on the MIL and stores this DTC.
