Transale fluid temperature (TFT) sensor range/performance (stuck) (P0711)
• Input voltage from TFT sensor to PCM terminal 3D and 2H maintains 0.06 V when 180 seconds have passed
after engine is started, vehicle is driven for 150 seconds or more at vehicle speed between 25 and 59 km/h
{15 and 36 mph}, then 60 km/h {37 mph} or more for 100 seconds or more.
Transale fluid temperature (TFT) sensor circuit malfunction (Open or short) (P0712)
• Input voltage from TFT sensor to PCM terminal 3D and 2H maintains 0.06 V when vehicle speed is above 20
km/h {12 mph}.
Transale fluid temperature (TFT) sensor circuit malfunction (short to ground) (P0713)
• Input voltage from TFT sensor to PCM terminal 3D and 2H maintains 4.67 V when vehicle speed is above 20
km/h {12 mph}.
Input/turbine speed sensor circuit malfunction (P0715)
• No input/turbine speed sensor signal to PCM terminals 3J and 3G when vehicle speed is above 40 km/h {25
mph} and selector lever position is at D, S, or L range.
Gear incorrect (P0731, P0732, P0733, P0734)
• If the RPM difference between the forward clutch drum revolution and differential gear case revolution eceeds
or falls below the pre-programmed RPM difference in the PCM while driving in each gear, the OBD system
judges “gear incorrect”.
Gear 1 incorrect (P0731)
• Revolution ratio of forward clutch drum revolution to differential gear case revolution is below 2.157 while in
1GR.
Gear 2 incorrect (P0732)
• Revolution ratio of forward clutch drum revolution to differential gear case revolution is below 1.249 or above
2.157 while in 2GR.
Gear 3 incorrect (P0733)
• Revolution ratio of forward clutch drum revolution to differential gear case revolution is below 0.863 or above
1.249 while in 3GR.
Gear 4 incorrect (P0734)
• Revolution ratio of forward clutch drum revolution to differential gear case revolution is below 0.6 or 1.249 or
above while in 4GR.
Torque converter clutch (TCC) (Stuck off) (P0741)
• Difference between engine speed and turbine speed more than 100 rpm while in TCC operation.
Torque converter clutch (TCC) (Stuck on) (P0742)
• Difference between engine speed and turbine speed below 50 rpm while TCC no operation.
Pressure control solenoid valve malfunction (P0745)
• If voltage is stuck at 0V or B+ in pressure control solenoid control terminal 3Y of the PCM when the solenoid
valve operates according to PCM calculation.
Shift solenoid A malfunction (Stuck off) (P0751)
• Revolution ratio of forward clutch drum revolution to differential gear case revolution within 0.91–1.09 and
DTCs not output
Shift solenoid A malfunction (Stuck on) (P0752)
• Input/turbine speed sensor signal 188 rpm or above while vehicle stop
Shift solenoid A malfunction (electrical) (P0753)
• If voltage is stuck at 0V or B+ in shift solenoid A control terminal 4AB of the PCM when the solenoid valve
operates according to PCM calculation.
Shift solenoid B malfunction (stuck off) (P0756)
• Revolution ratio of forward clutch drum revolution to differential gear case revolution below 2.157 and DTCs not
output.
Shift solenoid B malfunction (stuck on) (P0757)
• Revolution ratio of forward clutch drum revolution to differential gear case revolution below 1.249 or more than
2.157 in driving in D range.
Shift solenoid B malfunction (electrical) (P0758)
• If voltage is stuck at 0V or B+ in shift solenoid B control terminal 4AC of the PCM when the solenoid valve
operates according to PCM calculation.
Shift solenoid C malfunction (stuck off) (P0761)
• Revolution ratio of forward clutch drum revolution to differential gear case revolution below 2.157 in driving in D
range.
Shift solenoid C malfunction (stuck on) (P0762)
• Revolution ratio of forward clutch drum revolution to differential gear case revolution below 0.863 or 1.249 or
above in driving in D range.
Shift solenoid C malfunction (electrical) (P0763)
• If voltage is stuck at 0V or B+ in shift solenoid C control terminal 4Y of the PCM when the solenoid valve
operates according to PCM calculation.
Shift solenoid D malfunction (stuck off) (P0766)
• Revolution ratio of forward clutch drum revolution to differential gear case revolution below 0.6 or 1.249 or
above in driving in 4GR at D range.
