Coolant Temperature Sensor
- Coolant temperature sensor is located on intake manifold. Remove coolant temperature sensor. Place sensing portion of coolant temperature sensor in water.
- Gradually heat water and read resistance values across terminals. See COOLANT TEMPERATURE SENSOR RESISTANCE table. If coolant temperature sensor resistance is not within specification, replace sensor.
