P0712 Transmission Fluid Temperature Sensor \'A\' Circuit Low Input

General Information

Component Location





General Description

The automatic Oil temperature sensor is installed in the Valve Body. This sensor uses a thermistor whose resistance changes according to the temperature changes.
The TCM supplies a 5 V reference voltage to the sensor, and the output voltage of the sensor changes when the ATF temperature varies.
The Oil (ATF) temperature provides very important data for the TCM's control of the Torque Converter Clutch, and is also used for many other purposes.

DTC Description

This DTC code is set when the ATF temperature output voltage is lower than a value generated by thermistor resistance, in a normal operating range, for approximately 1 second or longer. The TCM regards the ATF temperature as fixed at a value of 80 °C (176°F).
