P2762 Torque Converter Clutch Control Solenoid Valve Feedback Current Stuck (SLU) - General Information

Component Location





General Description

The PCM/TCM controls the locking and unlocking of the Torque Converter Clutch (or Torque Converter Clutch), to the input shaft of the transmission, by applying hydraulic pressure. The main purpose of T/C clutch control is to save fuel by decreasing the hydraulic load inside the T/C. The PCM/TCM outputs current to control the Torque Converter Clutch Control Solenoid Valve (TCCSV) and hydraulic pressure is applied to the TCC according to the TCC current value. When the amount of current is high, high pressure is applied and the Torque Converter Clutch is locked. The normal operating range of the Torque Converter Clutch Control current value is from 200 mA (unlocked) to 1000 mA (locked).

DTC Description

TCM control slip amount (Engine rpm - Turbine rpm) of Torque convertor clutch and rise up duty ratio of SLU solenoid in order to engage for Torque convertor clutch. TCM set this code If feedback current and measured current are not match.
(Warning lamp : continuously 2 driving cycle)
