The ambient temperature sensor uses resistance to indicate outside air temperature. If it's below a preset temperature, usually around (~50Â° F), the EATC will prevent clutch engagement/compressor operation and blend cool outside air instead. Answer B is correct. The automatic temperature control module uses several input sensors. The ambient or outside air temperature sensor is a variable resister. If the outside temperature is colder than the factory set value, or the sensor or it's circuit is faulty, the automatic temperature control will not engage the compressor clutch. Answer C is wrong. Technician B is correct.
