DTC P0711 Transmission Fluid Temperature Sensor "A" Performance: Description

The ATF (Automatic Transmission Fluid) temperature sensor converts the fluid temperature into a resistance value for use by the TCM.

The TCM applies a voltage to the temperature sensor through terminal OIL of the TCM.

The sensor resistance changes with the transmission fluid temperature. As the temperature becomes higher, the sensor resistance decreases.

One terminal of the sensor is grounded so that the sensor resistance decreases and the voltage goes down as the temperature becomes higher.

The TCM calculates the fluid temperature based on the voltage signal.

DTC DETECTION CONDITION AND TROUBLE AREA

DTC No. DTC Detection Condition Trouble Area
P0711 Both (a) and (b) are detected (2-trip detection logic):
  1. Intake air and engine coolant temps, are more than -10°C (14°F) at engine start.
  2. After normal driving for over 16 min. and 40 sec. and 5 mile (8 km) or more, ATF temp, is less than 20°C (68°F).
  • Transmission wire (ATF temperature sensor)
  • TCM
