1.
Connect Scantool.
2.
Engine "ON".
3.
Monitor the "INPUT & OUTPUT SPEED SENSOR" parameter on the scantool.
4.
Accelerate the Engine speed until about 2000 rpm in the 4th gear.
Specification : INPUT SPEED - (OUTPUT SPEED × GEAR RATIO) ≤ 200 RPM

5.
Is "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.

GENERAL DESCRIPTION
E2F16E1A
The value of the input shaft speed should be equal to the value of the output shaft speed, when multiplied by the 5th gear
ratio, while the transaxle is engaged in the 5th gear. For example, if the output speed is 1,000 rpm and the 5th gear ratio
is 0.868, then the input speed is 868 rpm.
DTC DESCRIPTION
E0A9DE14
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 5th
gear ratio, while the transaxle is engaged in 5th gear. This malfunction is mainly caused by mechanical troubles such as
control valve sticking or solenoid valve malfunctioning rather than an electrical issue.
DTC DETECTING CONDITION
E705144B
Item
Detecting Condition
Possible cause
DTC Strategy
• 5th gear incorrect ratio
Enable Conditions
• Engine speed >450rpm
• Output speed >900rpm
• After 2 sec is passed from shift finish of
shift to 5th gear
• Input speed > 0rpm
• A/T oil temp sensor voltage <4.5V
• Voltage of Battery >10V
• TRANSAXLE RANGE SWITCH is normal
Threshold value
• ㅣInput speed/5th gear ratio - output speed
ㅣ ≥ 200rpm
Diagnostic Time
• More than 1sec
Fail Safe
• Locked into 3 rd gear.(If diagnosis code 0735 is output
four times, the transaxle is locked into 3rd gear)
• Faulty Input speed sensor
• Faulty output speed sensor
• Faulty UD clutch or 2nd brake
