Transmission Fluid Temperature Sensor Inspection
Reference: TRANSMISSION FLUID TEMPERATURE SENSOR REMOVAL AND INSTALLATION
Immerse transmission fluid temperature sensor (1) in water or oil. Check transmission fluid temperature sensor resistance between terminals of connector. Thus make sure its resistance decreases as temperature rises.
If sensor resistance is out of specification, replace solenoid wire harness (2).
Transmission fluid temperature sensor resistance
10 °C (50 °F): 6.445 kΩ
25 °C (77 °F): 3.5 kΩ
110 °C (230 °F): 0.247 kΩ
