DTC : P0712 (6-Speed A/T) (2016 2017 2018 2019 2020): General Description
The ATF temperature sensor is a thermistor type sensor that changes resistance according to the change in ATF temperature. The powertrain control module (PCM) sends a 5 V reference signal to the sensor through a pull-up resistor. When the ATF temperature is low, the sensor resistance increases and the PCM detects a high signal voltage. As the ATF temperature rises, the sensor resistance decreases and the PCM detects a low signal voltage. When the ATF temperature sensor signal voltage to the PCM is below specification, indicating that the temperature is above specification (a short to ground), the PCM detects a malfunction and stores a DTC.
