DTC P0712: Short in ATF Temperature Sensor
Circuit
NOTE:
• Before you troubleshoot, record all freeze data and
any on-board snapshot with the HDS, and review
General Troubleshooting Information (see page 14-4).
• This code is caused by an electrical circuit problem
and cannot be caused by a mechanical problem in the
transmission.
1. Turn the ignition switch to ON (II).
2. Check the ATF Temp Sensor voltage in the Data List
with the HDS.
Is the AT F T emp Sensor voltage 0.07 V or less?
YES − Go to step 3.
−
NO Intermittent failure, the system is OK at this
time. Check for an intermittent short to body
ground in the ATFT wire between the ATF
temperature sensor and the PCM.
3. Turn the ignition switch to LOCK (0).
4. Disconnect the shift solenoid wire harness
connector.
5. Turn the ignition switch to ON (II).
6. Check the ATF Temp Sensor voltage in the Data List
with the HDS.
Is the AT F T emp Sensor voltage 0.07 V or less?
YES − Go to step 7.
−
NO Replace the ATF temperature sensor
(see page 14-239), then go to step 12.
7. Turn the ignition switch to LOCK (0).
8. Jump the SCS line with the HDS.
9. Disconnect PCM connector B (49P).
10. Check for continuity between shift solenoid
harness connector terminal No. 6 and body ground.
SHIFT SOLENOID HARNESS CONNECTOR
ATFT (RED/YEL)
Wire side of female terminals
Is there continuity?
YES − Repair short to body ground in the wire
between PCM connector terminal B28 and shift
solenoid harness connector terminal No. 6, then go
to step 12.
NO − Go to step 11.
11. Remove the shift solenoid wire harness (see page
14-226), and check for continuity between shift
solenoid harness connector terminal No. 6 and
body ground. Do not disconnect the shift solenoid
valve D connector.
SHIFT SOLENOID HARNESS CONNECTOR
ATFT (WHT)
Terminal side of male terminals
Is there continuity?
YES − Replace the ATF temperature sensor
(see page 14-239), then go to step 12.
−
NO Go to step 18.
