Using an ohmmeter, measure the resistance between the terminals:
- 68°F (20°C) at 2.32 to 2.59 kilo ohms.
- 176°F (80°C) at 0.310 to 0.326 kilo ohms.
If the resistance is not as specified, replace the ECT sensor.
NOTEWhen checking the engine coolant temperature sensor in water, do not allow water to go into the terminals. After checking, dry the sensor.
