Engine Coolant Temperature Sensor: Inspection
- Check that the engine coolant temperature sensor has no deformation, cracks or other damages.
- Immerse the engine coolant temperature sensor and a thermometer in water.CAUTION:
Take care not to allow water to get into the engine coolant temperature sensor connector. Completely remove any water inside.
- Raise water temperature gradually, measure the resistance between the engine coolant temperature sensor terminals when the temperature is 20°C (68°F) and 80°C (176°F).NOTE:
Agitate the water for even temperature distribution.
Water temperature Terminal No. Standard 20°C (68°F) 1 - 2 2.25 - 2.65 kΩ 80°C (176°F) 0.305 - 0.331 kΩ
