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 1.581, then the input speed is 1,581 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 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 malfuctioning rather than an electrical issue.
Item | Detecting Condition & Limp Home | Possible Cause |
DTC Strategy | ● Rationality-high | ● Inspection components related to the OWC and REAR clutch in A/T ● In case of incorrection of output speed signal ● In case of incorrection of output speed signal |
Enable Conditions | ● Engine speed >400rpm, ● Output shaft speed >500rpm, ● Shift stage 2st. gear, ● Input speed >0rpm, ● A/T oil temperature >10℃ ● A/T range switch rationality Only one signal ● A/T range switch D, 2, L ● Time after shift changing finish >2sec | |
