P2759 Lexus Code - Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical Shift Solenoid Valve SLU
Quick Answer
The Engine Control Module (ECM) uses the signals from the throttle position sensor, airflow meter, input turbine speed sensor, output speed sensor, and crankshaft position sensor to monitor the engagement condition of the lock-up clutch. Common causes include Faulty Torque Converter Clutch Pressure Control Solenoid (Shift Solenoid Valve SLU), Torque Converter Clutch Pressure Control Solenoid harness is open or shorted, Torque Converter Clutch Pressure Control Solenoid circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2759 Lexus Description
The ECM compares the engagement condition of the lock-up clutch with the lock-up schedule in the ECM memory to detect mechanical problems of the shift solenoid valve (SLU), valve body, and torque converter.
When an open or short in the shift solenoid valve SLU circuit is detected, the ECM determines there is a malfunction. The ECM will turn on the MIL and store the Diagnostic Trouble Code (DTC).

- Faulty Torque Converter Clutch Pressure Control Solenoid (Shift Solenoid Valve SLU)
- Torque Converter Clutch Pressure Control Solenoid harness is open or shorted
- Torque Converter Clutch Pressure Control Solenoid circuit poor electrical connection
- Faulty Engine Control Module (ECM)
