Coolant Temperature Sensor
Disconnect negative battery cable. Remove coolant temperature sensor. Suspend coolant temperature sensor in a container filled with water. Place a thermometer in container. Connect ohmmeter between coolant temperature sensor connector terminals. See Fig 1 . Gradually heat water and check sensor resistance. See COOLANT TEMPERATURE SENSOR RESISTANCE SPECIFICATIONS table. If resistance is not as specified, replace coolant temperature sensor.
