NOTE:
- Before you troubleshoot, review the General Troubleshooting Information .
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

| P0712 CVT Fluid Temperature Sensor (Short) |
DTC(CVT)
- Problem verification
-1. Turn the vehicle to the ON mode.
-2. Check the parameter(s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit CVTF Temp Sensor (V) Less than 0.07 V Do the current condition(s) match the threshold?
YES
The failure is duplicated. Go to step 2.
NO
Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between the transmission fluid temperature sensor and the TCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/onboard snapshot.
- Transmission fluid temperature sensor check
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Disconnect the following connector.
Solenoid wire harness A 8P connector -3. Turn the vehicle to the ON mode.
-4. Check the parameter(s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit CVTF Temp Sensor (V) Less than 0.07 V Do the current condition(s) match the threshold?
YES
The transmission fluid temperature sensor is OK. Go to step 3.
NO
Faulty transmission fluid temperature sensor. Replace solenoid wire harness A .
- Shorted wire check (TATF line)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Jump the SCS line with the HDS, and wait more than 1 minute.
NOTE: This step must be done to protect the TCM from damage.
-3. Disconnect the following connector.
TCM 50P connector -4. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Solenoid wire harness A 8P connector: disconnected TCM 50P connector: disconnected Test point 1 TCM 50P connector No. 33 Test point 2 Body ground Is there continuity?
YES
Repair a short to ground in the TATF wire between solenoid wire harness A and the TCM.
NO
The TATF wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or replace the original TCM .
