DTC P0712: Transmission Fluid Temperature Sensor "A" Circuit Low Input; DTC P0713: Transmission Fluid Temperature Sensor "A" Circuit High Input [12/2013 - 11/2016]: Procedure

WARNING: This page is about a different car, the 2016 Toyota Highlander, 2015 Toyota Highlander, and 2014 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT TRANSMISSION WIRE (ATF TEMPERATURE SENSOR) 
    1. Remove the TCM from the transaxle.

      *a Component without harness connected
      (Transmission Wire)
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      17 (E2) - 18 (THO1) Always 79 Ω to 156 kΩ
      17 (E2) - Body ground and other terminals Always 10 kΩ or higher
      18 (THO1) - Body ground and other terminals Always 10 kΩ or higher

      HINT: 

      If the resistance is out of the specified range with the ATF temperature shown in the table below, the driveability of the vehicle may decrease.

      ATF Temperature Specified Condition
      10°C (50°F) 5 to 8 kΩ
      25°C (77°F) 2.5 to 4.5 kΩ
      110°C (230°F) 0.22 to 0.28 kΩ

      Result

      Proceed to
      OK
      NG

    Result:  1

    OK 

    REPLACE TCM. Refer to  COMPONENTS [12/2013 - 11/2016] 

    Result:  2

    NG 

    See step  2

  2. INSPECT ATF TEMPERATURE SENSOR 
    1. Disconnect the ATF temperature sensor connector from the transmission wire.
