Take care not to allow water to get into the engine coolant temperature sensor connector. Completely remove any water inside.
(A) | Thermometer | (B) | Engine coolant temperature sensor | (C) | Hexagonal part height: To approx.1/3 |
3. 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 |
