DTC P0710-11: Transmission Fluid Temperature Sensor "A" Circuit Short To Ground [04/2018 -]: Procedure

1. Warm up the engine.
2. Turn the engine switch off.
3. Connect the Techstream to the DLC3.
4. Turn the engine switch on (IG).
5. Turn the Techstream on.
6. Enter the following menus: Powertrain / Transmission / Data List / A/T Oil Temperature No. 1.
7. Read the Data List according to the display on the Techstream.

   Powertrain > Transmission > Data List 

   Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
   A/T Oil Temperature No. 1	ATF temperature sensor value	Min.: -40°C (-40°F) Max.: 150°C (302°F)	Approximately 80°C (176°F): After stall speed test Equal to ambient temperature: When engine is cold	If value is -40°C (-40°F) or 150°C (302°F), ATF temperature sensor circuit is open or shorted

   Powertrain > Transmission > Data List 

   Tester Display
   A/T Oil Temperature No. 1

B 

See step  2

1. Disconnect the C56 ECM connector.
2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   C56-86 (THO1) - C56-133 (ETHW)	Always	79 Ω to 156 kΩ
   C56-133 (ETHW) - Body ground	Always	10 kΩ or higher
   C56-86 (THO1) - Body ground	Always	10 kΩ or higher

   HINT: 

   If the resistance is out of the specified range at any of the ATF temperatures 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
