A/T Fluid Temperature Sensor Continuity Check

Remove the A/T fluid temperature sensor.

Measure the resistance between terminals 1 and 2 of the A/T fluid temperature sensor connector.

Standard value:

STANDARD VALUE

A/T 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

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).

If the A/T fluid temperature sensor resistance is outside the specified range and the "N" range indicator light is flashing, replace the A/T fluid temperature sensor.
