General Description
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 input speed is 1000 rpm and the 3rd gear ratio is 1.000, then the output speed is approx. 1000 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 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 malfuctioning rather than an electrical issue.
DTC Detecting Condition
Item | Detecting Condition | Possible Cause |
DTC Strategy | ? 3rd gear incorrect ratio | ? Faulty Input speed sensor ? Faulty output speed sensor ? Faulty R/D or F/C or E/C F/C-Front Clutch F/C-Front Clutch E/C - End Clutch OWC - One Way Clutch K/D - Kicdown brake L/R - Low & Reverse brake |
Enable Conditions | ? Engine speed >400rpm ? Output speed(PG-B) >600rpm ? Shift stage 3rd. gear ? Input speed(PG-A) >300rpm ? A/T fluid temp sensor voltage >-10? ? Inhibitor switch : "D" ? Solenoid is normal |
Threshold Value | ??Input speed/3rd gear ratio - output speed|=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) |
