| P0712 ATF Temperature Sensor (Short) |
DTC (A/T)
- 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 ATF 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 an intermittent short to ground in the TATF wire between the ATF temperature sensor and the PCM. 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/on-board snapshot.
- ATF temperature sensor check
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Disconnect the following connector.
ATF temperature sensor 2P 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 ATF Temp Sensor (V) Less than 0.07 V Do the current condition(s) match the threshold?
YES
The ATF temperature sensor is OK. Go to step 3.
NO
- Shorted wire check (TATF line)
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Jump the SCS line with the HDS.
- 3. Disconnect the following connector.
- 4. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode ATF temperature sensor 2P connector: disconnected PCM connector B (51P): disconnected Test circuit TATF Test point 1 ATF temperature sensor 2P connector No. 1 (GRN) Test point 2 Body ground Is there continuity?
YES
Repair a short to ground in the TATF wire between the ATF temperature sensor and the PCM.
NO
The TATF wire is OK. Update the PCM if it does not have the latest software , or substitute a known-good PCM - Refer to: How to Troubleshoot the A/T System (2014 2015), or How to Troubleshoot the Fuel and Emissions Systems, or How to Troubleshoot the Brake Booster Pressure Monitoring System (2016 2017 2018 2019 2020), or How to Troubleshoot the Fuel and Emissions Systems(With Auto Idle Stop System) (2016) .
