Automatic Transaxle System DTCS

AUTOMATIC TRANSAXLE SYSTEM DIAGNOSTIC TROUBLE CODE (DTC) LIST

DTC No. Diagnosis item
P0712 Fluid temperature sensor system 
If the fluid temperature sensor output voltage is 4.59 V or more even after driving for 1 second, it is judged that there is an open or a short to battery in the fluid temperature sensor and diagnosis code P0713 is set.
P0713 Fluid temperature sensor system 
If the fluid temperature sensor output voltage is 0.07 V or less even after driving for 1 second, it is judged that there is a short to ground in the fluid temperature sensor and diagnosis code P0712 is set.
P0715 Input shaft speed sensor system 
If no output pulse is detected from the input shaft speed sensor for 1 second or more while driving in 3rd or 4th gear at a speed of 30 km/h or more, there is judged to be an open circuit or a short circuit in the input shaft speed sensor and diagnosis code P0715 is set.
P0720 Output shaft speed sensor system 
If the output from the output shaft speed sensor is continuously 50% lower than the vehicle speed for 1 second or more while driving in 3rd or 4th gear at a speed of 30 km/h or more, there is judged to be an open circuit or a short circuit in the output shaft speed sensor and diagnosis code P0720 is set.
P0703 Brake switch system 
If the brake switch is ON for 5 minutes or more while driving, it is judged that there is an open or a short to battery in the brake switch and diagnosis code P0703 is set.
P0750 Low and reverse solenoid valve system 
If the resistance value for a solenoid valve is too large or too small, it is judged that there is a short circuit or an open circuit in the solenoid valve and the respective diagnosis code P0750 is set. The transmission is locked into 3rd gear as a fail-safe measure.
P0755 Underdrive solenoid valve system 
If the resistance value for a solenoid valve is too large or too small, it is judged that there is a short circuit or an open circuit in the solenoid valve and the respective diagnosis code P0755 is set. The transmission is locked into 3rd gear as a fail-safe measure.
P0760 Second solenoid valve system 
If the resistance value for a solenoid valve is too large or too small, it is judged that there is a short circuit or an open circuit in the solenoid valve and the respective diagnosis code P0760 is set. The transmission is locked into 3rd gear as a fail-safe measure.
P0765 Overdrive solenoid valve system 
If the resistance value for a solenoid valve is too large or too small, it is judged that there is a short circuit or an open circuit in the solenoid valve and the respective diagnosis code P0765 is set. The transmission is locked into 3rd gear as a fail-safe measure.
P0743 Damper clutch control solenoid valve system 
If the resistance value for a solenoid valve is too large or too small, it is judged that there is a short circuit or an open circuit in the solenoid valve and the respective diagnosis code P0743 is set. The transmission is locked into 3rd gear as a fail-safe measure.
P0731 1st gear synchronous error 
If the output from the output shaft speed sensor multiplied by the 1st gear ratio is not the same as the output from the input shaft speed sensor after the shift to 1st gear has been completed, diagnosis code P0731 is set. If diagnosis code P0731 is set four times, the transmission is locked into 3rd gear as a fail-safe measure.
P0732 2nd gear synchronous error 
If the output from the output shaft speed sensor multiplied by the 2nd gear ratio is not the same as the output from the input shaft speed sensor after the shift to 3rd gear has been completed, diagnosis code P0732 is set. If diagnosis code P0732 is set four times, the transmission is locked into 3rd gear as a fail-safe measure.
P0733 3rd gear synchronous error 
If the output from the output shaft speed sensor multiplied by the 3rd gear ratio is not the same as the output from the input shaft speed sensor after the shift to 3rd gear has been completed, diagnosis code P0733 is set. If diagnosis code P0733 is set four times, the transmission is locked into 3rd gear as a fail-safe measure.
P0734 4th gear synchronous error 
If the output from the output shaft speed sensor multiplied by the 4th gear ratio is not the same as the output from the input shaft speed sensor after the shift to 4th gear has been completed, diagnosis code P0734 is set. If diagnosis code P0734 is set four times, the transmission is locked into 3rd gear as a fail-safe measure.
P0736 Reverse gear synchronous error 
If the output from the output shaft speed sensor multiplied by the reverse gear ratio is not the same as the output from the input shaft speed sensor after the shift to reverse gear has been completed, diagnosis code P0736 is set. If diagnosis code P0736 is set four times, the transmission is locked into 3rd gear as a fail-safe measure.
P1604 No ID from ECU 
  • No massage from ECU for
  • Input shaft speed > 1000rpm
  • 500ms passed from relay voltage greater than or equal to 10V
P1603 CAN communication BUS OFF 
  • CAN massage transfer error for
  • Input shaft speed > 1000rpm
  • 500mses passed from relay voltage greater than or equal to 10V
P0741 Damper clutch abnormal system 
  • Detect 4 times the lockup clutch control duty = 100% for 4 seconds.
  • When PCM commands lockup
P0742 Damper clutch stuck ON 
  • Torque converter slip rpm is less than or equal to 5rpm is continue for 10 seconds consecutively
  • All the other direct clutches are normal
