P0711 FLUID TEMPERATURE SENSOR FUNCTION

TRANSMISSION: GR6Z30A

P0711

Description


  • The fluid temperature sensor detects the transmission oil temperature in the oil pan.
  • The fluid temperature sensor converts the transmission oil temperature into output voltage and transmits the signal to TCM.
  • The fluid temperature sensor uses a thermistor and its electrical resistance varies as the temperature varies. The electrical resistance decreases as the temperature increases.

 		Fluid temperature sensor malfunction judgment
  • A DTC is set if TCM detects the fluid temperature sensor value of 160°C (320°F) or more for a certain period of time.
  • A DTC is set if TCM detects the fluid temperature sensor value of 0°C (32°F) or more and less than 20°C (68°F) for a certain period of time.
  • A DTC is set if TCM detects the fluid temperature sensor value of −20°C (−4°F) or more, or less than 0°C (32°F) for a certain period of time.
  • A DTC is set if TCM detects the fluid temperature sensor value of less than −20°C (−4°F) for a certain period of time.
