FUEL INJECTION (FUEL SYSTEMS)(H4DO(HEV)) > Engine Coolant Temperature Sensor
1. Check that the engine coolant temperature sensor has no deformation, cracks or other damages.
2. Immerse the engine coolant temperature sensor and a thermometer in water.
Take care not to allow water to get into the engine coolant temperature sensor connector. Completely remove any water inside.
Engine coolant temperature sensor
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).
Agitate the water for even temperature distribution.
