DTC P0712
DTC P0712: ATF Temperature Sensor (Short)
General Description
The ATF temperature sensor is integrated to the sensor unit in the transmission. The transmission control module (TCM) monitors output voltage of the ATF temperature sensor. If the ATF temperature sensor output voltage is a specified value for a specified duration, the TCM detects a malfunction and stores a DTC.

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the A/T gear position indicator blinks, the MIL comes on, and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the TCM memory.
Conditions for clearing the DTC
The A/T gear position indicator comes off by turning the vehicle to the OFF (LOCK) mode. The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command.
