DTC P0710-00: Transmission Fluid Temperature Sensor "A" Circuit Range/Performance [12/2019 - 10/2021]: Procedure

1. Read the DTCs using the GTS.

   Powertrain > Transmission > Trouble Codes 

   Result

   Result	Proceed to
   Only DTC P0710-00 is output	A
   DTC P0710-00 and P0710-15 are output	B
   DTC P0710-00 and other DTCs are output	C

   HINT: 

   If any DTCs other than DTC P0710-00 are output, perform troubleshooting for those DTCs first.

Result: 

B 

GO TO DTC CHART (DTC P0710-15). Refer to  DTC P0710-15: Transmission Fluid Temperature Sensor "A" Circuit Short to Battery or Open [12/2019 - 10/2022]  

Result: 

C 

GO TO DTC CHART. Refer to  DIAGNOSTIC TROUBLE CODE CHART [12/2019 - 10/2021] 

Result: 

A 

See step  2

1. Check the automatic transaxle fluid level.

   Refer to ADJUSTMENT [12/2019 - 10/2022]

   OK

   Automatic transaxle fluid level is correct.

   Proceed to
   OK
   NG

Result: 

NG 

ADJUST AUTOMATIC TRANSAXLE FLUID LEVEL. Refer to  ADJUSTMENT [12/2019 - 10/2022] 

Result: 

OK 

See step  3

1. Disconnect the C54 ECM connector.
2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   C54-86 (THO1) - C54-133 (ETHW)	ATF temperature 10°C (50°F)	5 to 8 kΩ
   C54-86 (THO1) - C54-133 (ETHW)	ATF temperature 110°C (230°F)	0.22 to 0.28 kΩ
   C54-133 (ETHW) - Body ground	Always	10 kΩ or higher
   C54-86 (THO1) - Body ground	Always	10 kΩ or higher

   HINT: 

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

   ATF Temperature	Specified Condition
   25°C (77°F)	2.5 to 4.5 kΩ

   Result

   Proceed to
   OK
   NG

Result: 

NG

PERFORM REGISTRATION. Refer to  REGISTRATION [12/2019 - 10/2022] 

1. Disconnect the C51 transmission wire connector.
2. Disconnect the C54 ECM connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   C51-1 (OT+) - C54-86 (THO1)	Always	Below 1 Ω
   C51-2 (OT-) - C54-133 (ETHW)	Always	Below 1 Ω
   C51-1 (OT+) or C54-86 (THO1) - Body ground	Always	10 kΩ or higher
   C51-2 (OT-) or C54-133 (ETHW) - Body ground	Always	10 kΩ or higher

   Result

   Proceed to
   OK
   NG

Result: 

OK 

REPLACE TRANSMISSION WIRE (ATF TEMPERATURE SENSOR). Refer to  COMPONENTS [12/2019 - 10/2022] 

Result: 

NG 

REPAIR OR REPLACE HARNESS OR CONNECTOR (TRANSMISSION WIRE - ECM)
