Temperature Sensor Circuit

  1. Turn ignition off. Connect an ohmmeter between terminal No. 2 and ground. Resistances for various temperatures will be as follows: 290-364 ohms at 175°F (80°C), 2280-2720 at 70°F (20°C), and 8260-10,560 ohms at 15°F (-10°C).
  2. If resistance is considerably higher than specified, an open circuit is indicated. If resistance is at or near zero ohms a short circuit is indicated.
