Transmission Fluid Temperature Sensor Check

  1. While pressing A in the figure, turn B counterclockwise to unlock the CVT assembly connector, and disconnect the connector.
  2. Measure the resistance between the sensor-side connector terminal No. 17 of the CVT assembly connector and ground (terminal No. 19).

    Standard value: 

    RESISTANCE CHART

    Fluid temperature °C (°F) Resistance kΩ
    At 0 (32) Approximately 15.5
    At 20 (68) Approximately 6.5
    At 40 (104) Approximately 3.1
    At 60 (140) Approximately 1.6
    At 80 (176) Approximately 0.9
    At 100 (212) Approximately 0.5
    NOTE: In the information screen on the multi-information display, the fluid temperature warning comes on when the transmission fluid temperature is approximately 140°C (284°F) or higher, and automatically goes out when the transmission fluid temperature dropped below approximately 137°C (279°F).

    CAUTION: The transmission fluid temperature sensor cannot be removed or replaced as a single unit. When the transmission fluid temperature sensor needs to be replaced, replace the valve body assembly.
  3. When the resistance of the transmission fluid temperature sensor is outside the standard value, and the fluid temperature warning comes on/goes out at other than the specified temperatures, replace the valve body assembly and the harness.
