Circuit Description

When the transmission fluid is cold, sensor resistance is high. As transmission fluid warms up, sensor resistance decreases. This diagnostic monitors Transmission Fluid Temperature (TFT) sensor circuit. Circuit may be functional but not in normal operating range. This diagnostic indicates stuck, erratic, intermittent, or skewed values, resulting in reduced system performance. TFT sensor range is -40 to 437°F (-40 to 225°C). If PCM detects an intermittent voltage or no voltage change in TFT sensor circuit, then DTC P0711 sets.
