Engine Coolant Temperature (ECT) Sensor
Remove ECT sensor. Place sensor and thermometer in container of water. Measure resistance between ECT sensor terminals. Slowly heat water. Note resistance at specified temperatures. See ECT SENSOR RESISTANCE SPECIFICATIONS table. Replace ECT sensor as necessary.
