ECT Sensor Inspection
Reference: ECT SENSOR REMOVAL AND INSTALLATION
Check ECT sensor resistance as follows.
- Check resistance between terminals "1" and "2". Make sure its resistance decreases as its temperature increases.
If measured resistance is out of specification, replace ECT sensor (1).
ECT sensor resistance
-20°C (-4°F): 13.51 - 16.17 kΩ
20°C (68°F): 2.290 - 2.620 kΩ
80°C (176°F): 0.309 - 0.331 kΩ
