DTC P0710-11: Transmission Fluid Temperature Sensor "A" Circuit Short To Ground [10/2017 - ]: Procedure
WARNING: This page does not describe the selected car, but rather 14 other vehicles, including the 2024 Lexus IS 350, 2024 Lexus IS 300, 2023 Lexus IS 350, 2023 Lexus IS 300, and 2022 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT TRANSMISSION WIRE (ATF TEMPERATURE SENSOR)
- Disconnect the F56 transmission wire connector.
*a Component without harness connected
(Transmission Wire) - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition 9 (OIL) - 1 (E2) Always 79 Ω to 156 kΩ 9 (OIL) - Body ground and other terminals Always 10 kΩ or higher 1 (E2) - Body ground and other terminals 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 drivability 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:
NG
REPAIR OR REPLACE TRANSMISSION WIRE (ATF TEMPERATURE SENSOR). Refer to COMPONENTS [04/2013 - ]
Result:
OK
See step 2
- Disconnect the F56 transmission wire connector.
- CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)
- Disconnect the F102 ECM connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition F102-86 (THO1) - Body ground and other terminals Always 10 kΩ or higher F102-133 (ETHW) - Body ground and other terminals Always 10 kΩ or higher Result
Proceed to OK NG
Result:
OK
REPLACE ECM. Refer to COMPONENTS [10/2017 - ]
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
