Code P0712 Honda Description

The Transmission Fluid Temperature Sensor is a thermistor-type sensor that changes resistance according to the change in transmission fluid temperature. The Powertrain Control Module (PCM) sends a 5 V reference signal to the sensor through a pull-up resistor. When the transmission fluid temperature is low, the sensor resistance increases, and the PCM detects a high signal voltage. As the transmission fluid temperature rises, the sensor resistance decreases and the PCM detects a low signal voltage. When the transmission fluid 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 Diagnostic Trouble Code (DTC).
