P0741 2013 Toyota RAV4 Code - Torque Converter Clutch Solenoid Performance

Quick Answer

Torque converter lock-up is controlled by the Engine Control Module (ECM) based on speed sensor NT, speed sensor NC, engine speed, engine load, engine temperature, vehicle speed, ATF temperature, and gear selection. Common causes include Low transmission fluid level, Dirty transmission fluid, Faulty Torque Converter Clutch Solenoid Valve (Shift Solenoid Valve SL). 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 P0741 2013 Toyota RAV4 Description

Torque converter lock-up is controlled by the Engine Control Module (ECM) based on speed sensor NT, 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 counter gear speed (NC). When conditions are appropriate, the ECM requests lock-up by applying a control voltage to shift solenoid valve SL. When the shift solenoid valve SL 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 SL or lock-up system performance. The ECM will turn on the MIL and store the Diagnostic Trouble Code (DTC).
