Kia Sedona (2008 year). Instruction — part 101

1. If there is no mechanical defaults in A/T, all slippages occur in torque converter.

2. Therefore, engine revolution is output, but input and output speed revolution must be "zero" due to

wheel's lock.

3. If 2nd brake system (2nd gear operating part) has faults, input speed revolution will be out of

specification.

4. If output speed revolution is output. It means that the foot brake force is not applied fully.

Remeasuring is required.

5. Is "STALL TEST" within specification?

YES



Go to "SIGNAL CIRCUIT INSPECTION" procedure.

NO



Go to "COMPONENT INSPECTION" procedure.

SIGNAL CIRCUIT INSPECTION

1. Connect Scan tool.

2. Engine "ON".

3. Monitor the "INPUT & OUTPUT SPEED SENSOR" parameter on the scan tool.

4. Accelerate the Engine speed until about 2000 RPM in the 2nd gear.

Specification: INPUT SPEED - (OUTPUT SPEED x GEAR RATIO) < or = 200 RPM

CAUTION:

1. Do not let anybody stand In front of or behind the vehicle while

this test is being carried out.

2. Check the A/T fluid level and temperature and the engine

coolant temperature.



Fluid level: At the hot mark on the oil level gauge.



Fluid temperature: 176-212°F (80-100°C).



Engine coolant temperature: 176-212°F (80-100°C).

3. Chock both rear wheel (left and right).

4. Pull the parking brake lever on with the brake pedal fully

depressed.

5. The throttle should not be left fully open for more than eight

second.

6. If stall test is being performed more than once, move the

selector lever to `N' and run the engine at 1000 RPM to allow the
transaxle fluid to cool prior to subsequent tests.

5. Does "INPUT & OUTPUT SPEED SENSOR" within specifications?

YES



Go to "COMPONENT INSPECTION" procedure.

NO



Check for electrical noise of circuit in INPUT & OUTPUT SPEED SENSOR or Replace INPUT &
OUTPUT SPEED SENSOR. Repair as necessary and Go to "VERIFICATION OF VEHICLE
REPAIR" procedure.

3. Drive a car with gear position 2 in "SPORTS MODE".

4. Compare it with reference data as below.

Specification: refer to DTC P0731.

5. Is oil pressure value within specifications?

YES



Repair AUTO TRANSAXLE (Clutch or Brake) as necessary and Go to "VERIFICATION OF
VEHICLE REPAIR" procedure.

NO



Replace AUTO TRANSAXLE (BODY CONTROL VALVE faulty) as necessary and Go to
"VERIFICATION OF VEHICLE REPAIR" procedure.

VERIFICATION OF VEHICLE REPAIR

Refer to DTC P0731.

DTC P0733 GEAR 3 INCORRECT RATIO

COMPONENT LOCATION

GENERAL DESCRIPTION

The value of the input shaft speed should be equal to the value of the output shaft speed, when multiplied by the
3rd gear ratio, while the transaxle is engaged in the 3rd gear. For example, if the output speed is 1,000 RPM and
the 3rd gear ratio is 1.686, then the input speed is 1,686 RPM.

This code is set if the value of input shaft speed is not equal to the value of the output shaft, when multiplied by
the 3rd gear ratio, while the transaxle is engaged in 3rd gear. This malfunction is mainly caused by mechanical
troubles such as control valve sticking or solenoid valve malfunctioning rather than an electrical issue.
