Engine Coolant Temperature Sensor INSPECTION


FUEL INJECTION (FUEL SYSTEMS)(H4DO(HEV)) > Engine Coolant Temperature Sensor

INSPECTION

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.

CAUTION:

Take care not to allow water to get into the engine coolant temperature sensor connector. Completely remove any water inside.

(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.
