DTC P0741 TORQUE CONVERTER CLUTCH CIRCUIT - STUCK OFF
GENERAL DESCRIPTION
E07758A2
The PCM/TCM controls the locking and unlocking of the Torque Converter Clutch (or Damper Clutch), to the input shaft
of the transmission, by appling 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 duty pulses to control the Damper Clutch Control Solenoid
Valve(DCCSV) and hydraulic pressure is applied to the DC according to the DCC duty ratio value. When the duty ratio
is high, high pressure is applied and the Damper Clutch is locked. The normal operating range of the Damper Clutch
Control duty ratio value is from 30%(unlocked) to 85%(locked).
DTC DESCRIPTION
EAAEC30F
The PCM/TCM increases the duty ratio to engage the Damper Clutch by monitoring slip rpms (difference vlaue beteween
engine speed and turbine speed). To decrease the slip of the Damper Clutch, the PCM/TCM increases the duty ratio by
appling more hyraulic pressure. When slip rpm does not drop with 100% duty ratio, the PCM/TCM determines that the
Torque Converter Clutch is stuck OFF and sets this code.
