P2769 Scion Code - Short in Torque Converter Clutch Solenoid Circuit Shift Solenoid Valve SL
Quick Answer
Shift solenoid valve SL is turned on and off by signals from the Engine Control Module (ECM) to control the hydraulic pressure acting on the lock-up relay valve, which then controls the operation 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 P2769 Scion Description
Based on the signals from the throttle position sensor, airflow meter, and crankshaft position sensor, the ECM sends a signal to shift solenoid valve SL to regulate the hydraulic pressure and provide smooth torque converter engagement. Shift solenoid valve SL responds to commands from the ECM. The valve controls the lock-up relay valve to perform the torque-converter lock-up function. If the ECM detects an open or short circuit for shift solenoid valve SL, it will illuminate the MIL and store the Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P2769 Scion?
- 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)
