P2757 Toyota Code - Torque Converter Clutch Pressure Control Solenoid Performance 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 P2757 Toyota Description

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.
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.
Torque converter lock-up is controlled by the ECM based on the input turbine speed sensor (speed sensor NT), output speed sensor (speed sensor NC), engine speed, engine load, engine temperature, vehicle speed, ATF temperature and gear selection. The ECM determines the lock-up status of the torque converter by comparing the engine speed (NE) to the input turbine speed (NT). The ECM calculates the actual transmission gear by comparing the input turbine speed (NT) to the output shaft speed (NC). When conditions are appropriate, the ECM requests lock-up by applying control voltage to shift solenoid valve SLU. When shift solenoid valve SLU is turned on, it applies pressure to the lock-up relay valve and locks the torque converter.
If the ECM detects no lock-up after lock-up has been requested or if it detects lock-up when it is not requested, the ECM interprets this as a fault in shift solenoid valve SLU or lock-up system performance.
The ECM will turn on the MIL and store the Diagnostic Trouble Code (DTC).
