GENERAL DESCRIPTION
E2F0A586
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.
DTC DESCRIPTION
E6DFDA57
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.
DTC DETECTING CONDITION
E0EAA5E4
Item
Detecting Condition
Possible cause
DTC Strategy
• 3rd gear incorrect ratio
Enable Conditions
• Engine speed > 450rpm
• Output speed >900rpm
• After 2 sec is passed from shift finish of
shift to 3rd gear
• Input speed > 0rpm
• A/T oil temp > -23.5 C(-9.4 F)
• Voltage of Battery >10V
• TRANSAXLE RANGE SWITCH is normal
Threshold value
• ㅣ Input speed/3rd gear ratio - output
speed ㅣ ≥ 200rpm
Diagnostic Time
• more than 1sec
Fail Safe
• Locked into 3 rd gear.(If diagnosis code
P0733 is output four times, the transaxle
is locked into 3rd gear)
• Faulty Input speed sensor
• Faulty output speed sensor
• Faulty UD clutch or OD clutch
