Transmission Fluid Temperature Sensor Check

Measure the resistance between terminals No. 1 and No. 2 of the transmission fluid temperature sensor connector.

TRANSMISSION FLUID TEMPERATURE SENSOR RESISTANCE CHART (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

If the transmission fluid temperature sensor resistance is outside the specified range and the "A/T TEMP" indicator light is illuminating, replace the transmission fluid temperature sensor.
NOTE: The "A/T TEMP" indicator light on the combination meter illuminating when the temperature reaches approximately 125°C (257°F) or greater, and then stops illuminating when the temperature drops below approximately 115°C (238°F).
