DTC P0732 GEAR 2 INCORRECT RATIO
COMPONENT LOCATION
Fig. 49: Identifying Gear 2 Incorrect Ratio Component Location
Courtesy of KIA MOTORS AMERICA, INC.
GENERAL DESCRIPTION
The value of the input shaft speed should be equal to the value of the output shaft speed, when multiplied by the
2nd gear ratio, while the transaxle is engaged in the 2nd gear. For example, if the output speed is 1000 RPM and
the 2nd gear ratio is 2.442, then the input speed is 2,442 RPM.
DTC DESCRIPTION
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 2nd gear ratio, while the transaxle is engaged in 2nd gear. This malfunction is mainly caused by mechanical
troubles such as control valve sticking or solenoid valve malfunctioning rather than an electrical issue.
