Transmission Fluid Temperature Sensor Check
- Remove the transmission fluid temperature sensor.
- Measure the resistance between terminals 1 and 2 of the transmission fluid temperature sensor connector.Fig 1: Measuring Resistance Between Terminals 1 And 2 Of Transmission Fluid Temperature Sensor Connector

RESISTANCE SPECIFICATIONTRANSMISSION 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 shift indicator light (D or 1 through 4 or 5) is flashing, replace the transmission fluid temperature sensor.NOTE: The selector lever position indicator light (D, 1 through 4 or 5) 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).
