What does code P1711 mean?

P1711 · FordTransmission Fluid Temperature Sensor Out of Self-Test Range

P1711 on Ford vehicles means the transmission fluid temperature sensor (TFT) sent a voltage reading outside the expected range during the transmission control module's (TCM) self-test routine. The TCM runs this self-test at key-on or during specific operating conditions, and when the sensor signal falls outside the calibrated window, it flags this code and may substitute a default fluid temperature value.
