瀚慖f less than the specified range, replace the wiring harness.
5. Test for the resistance between the B13 Automatic Transmission Fluid Temperature Sensor signal circuit terminal 7 X2 and the low reference
circuit terminal 8 X2. Refer to Transmission Fluid Temperature Sensor Specifications (See: Transmission and Drivetrain/Automatic
Transmission/Transaxle/Specifications/Pressure, Vacuum and Temperature Specifications) for the resistance values.
瀚慖f not within the specified range, replace the wiring harness.
6. If the circuit test normal, replace the K71 Transmission Control Module.
Repair Instructions

DTC Descriptors
DTC P0711
- Transmission Fluid Temperature (TFT) Sensor Performance
DTC P0712
- Transmission Fluid Temperature (TFT) Sensor Circuit Low Voltage
DTC P0713
- Transmission Fluid Temperature (TFT) Sensor Circuit High Voltage
Circuit/System Description
The transmission fluid temperature (TFT) sensor is located inside of the transmission control module (TCM) assembly which has no serviceable
components. The TFT sensor provides transmission fluid temperature to the TCM. This fault is handled inside the TCM and no external circuits are
involved.
