Coolant Temperature Sensor

  1. Sensor is located on the intake manifold on 1.6L engine and thermostat housing on 2.0L engine. Disconnect coolant temperature sensor connector and measure resistance between sensor terminals.
  2. Check resistance at more than one temperature to ensure resistance changes with temperature. Replace sensor if it is not within specification. See COOLANT TEMPERATURE SENSOR RESISTANCE table.
