Refrigerant Temperature Sensor
WARNING: This page is about a different car, the 1991 Plymouth Colt Vista, 1991 Mitsubishi Pickup, 1991 Mitsubishi Montero, 1991 Dodge Ram 50, and 1991 Dodge Colt Vista. However, it is still accessible from the selected car via links, so may be relevant.
Disconnect refrigerant temperature sensor electrical connector. Using an ohmmeter, measure resistance between terminals. At 77°F (25°C) resistance should be approximately 80,470 ohms. If resistance deviates greatly, replace sensor.
