The value of the input shaft speed should be equal to the value of the output shaft speed, when multiplied by the reverse gear ratio, while the transaxle is engaged in the reverse gear. For example, if the output speed is 1,000 rpm and the reverse gear ratio is 4.586, then the input speed is 4,586 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 reverse gear ratio, while the transaxle is engaged in reverse 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 | Possible cause |
DTC Strategy | ● Reverse gear incorrect ratio | ● Faulty Input speed sensor ● Faulty output speed sensor ● Faulty RVS clutch or L/R brake |
Enable Conditions | ● Engine speed >450rpm ● Output speed >100rpm ● Shift stage "R". gear ● Input speed >0rpm ● A/T oil temp output ≥ -23.5℃ ● Voltage of Battery >10V ● TRANSAXLE RANGE SWITCH is normal and after 2sec is passed from IG ON | |
Threshold Value | ●ㅣInput speed/Rev. gear ratio - output speed ㅣ≥200rpm | |
Diagnostic Time | ● More than 1sec | |
Fail Safe | ● Locked into 3rd gear.(If diagnosis code P0736 is output four times, the transaxle is locked into 3rd gear) |
