P0714Transmission Fluid Temperature Sensor A Circuit Intermittent
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Needs a drive cycle to confirm a fix
- How the car detects it
- The transmission fluid temperature sensor is an NTC thermistor whose resistance falls as the fluid warms; the module feeds it with 5 V through a resistor. A low signal therefore means very hot or a short to ground, a high signal very cold or an open circuit. P0714 means the signal drops out or jumps briefly – not long enough for P0712 or P0713. Ford's 2012 6R80 transmission names P0714 among its fluid temperature checks for open, short and in-range faults. Ram 6.7 bulletins of 2013 changed P0711–P0714 from a one-trip to a two-trip MIL to avoid needless warnings. GM files such jumps under P0711 instead. No source publishes thresholds for P0714 itself. A loose contact in the transmission connector or a chafing internal harness is the usual cause.
