Kia Sedona (2008 year). Manual - part 106

MONITOR SCAN TOOL DATA 

1. Connect scan tool to data link connector (DLC).  

2. Engine "ON".  

3. Select "D RANGE" and drive vehicle.  

4. Monitor the "TORQUE CONVERTER (DAMPER) CLUTCH" parameter on the scan tool. 

Specification: TCC SLIP > 5 RPM

5. Is TCC SLIP" within specifications? 

YES  



Fault is intermittent caused by poor contact in the sensor's and/or TCM (PCM)'s connector or was 
repaired and TCM (PCM) memory was not cleared. Thoroughly check connectors for looseness, 
poor connection, bending, corrosion, contamination, deterioration or damage. Repair or replace as 
necessary and go to "VERIFICATION OF VEHICLE REPAIR" procedure.  

NO  



Go to "COMPONENT INSPECTION" procedure.

2. Ignition "ON" & Engine "OFF".  

3. Select A/T solenoid valve actuator test and operate actuator test.  

4. Can you hear operating sound for using TCC SOLENOID VALVE actuator testing function? 

YES  



Go to step 2.  

NO  



Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR" 
procedure.  

2. CHECK OIL PRESSURE

1. Connect oil pressure gauge to "DR" ports.  

2. Ignition "ON" & Engine "OFF".  

3. After connecting scan tool and monitor the "TCC SOLENOID VALVE DUTY" parameter on the 

scan tool data list.  

4. Select 1st gear and accelerate Engine speed to 2500 RPM.  

5. Measure oil pressure. 

Specification: approx. 598.2034 kPa (6.1 kg/cm

DTC P0743 TORQUE CONVERTER CLUTCH CIRCUIT - ELECTRICAL 

COMPONENT LOCATION

GENERAL DESCRIPTION 

The PCM/TCM controls the locking and unlocking of the Torque Converter Clutch (or Damper 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 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 

The PCM/TCM checks the Damper Clutch Control Signal by monitoring the feedback signal from the solenoid 
valve drive circuit. If an unexpected signal is monitored (for example, high voltage is detected when low 
voltage is expected, or low voltage is detected when high voltage is expected) the PCM/TCM judges that 
DCCSV circuit is malfunctioning and sets this code.
