Transmission Fluid Temperature Sensor Check

  1. Remove the transmission fluid temperature sensor.
  2. Measure the resistance between terminals 1 and 2 of the transmission fluid temperature sensor connector.

    TRANSMISSION FLUID TEMPERATURE RESISTANCE STANDARD VALUE

    TRANSMISSION FLUID TEMPERATURE  RESISTANCE 
    0°C (32°F) 16.7 - 20.5 kΩ
    20°C (68°F) 7.3 - 8.9 kΩ
    40°C (104°F) 3.4 - 4.2 kΩ
    60°C (140°F) 1.9 - 2.2 kΩ
    80°C (176°F) 1.0 - 1.2 kΩ
    100°C (212°F) 0.57 - 0.69 kΩ
  3. If the transmission fluid temperature sensor resistance is outside the specified range and the "N" range indicator light is flashing, replace the transmission fluid temperature sensor.
NOTE: The "N" range indicator light on the combination meter flashes when the temperature reaches approximately 125°C (257 °F) or greater, and then stops flashing when the temperature drops below approximately 115°C (238°F).
