DTC P2762 (Flash Code 33) Torque Converter Clutch Pressure Control Solenoid (SLU) Control Circuit Performance (AWR6B45)

1. DTC P2762 description

Lock-up control solenoid (SLU) is installed on the valve body assembly and adjusts the lock-up clutch oil pressure. The TCM controls lock-up control solenoid (SLU) based on the engine speed, throttle opening position, turbine speed sensor signal, output speed sensor signal, etc. Lock-up control solenoid (SLU) performs the lock-up control and slip lock-up control by adjusting the lock-up clutch oil pressure. When the lock-up control solenoid is activated, the TCM accumulates the difference between the required solenoid current and the actual solenoid current as a feedback error current. If the TCM detects an abnormal lock-up control solenoid (SLU) feedback error current, the DTC is set.
