What is the purpose of the ambient air sensor?
The ambient (ATC) or outside air temperature sensor is an (NTC) negative temperature coefficient sensor that informs the semiautomatic/automatic temperature control system of outside air temperature. The NTC sensor’s resistance decreases as the outside air temperature increases. Herein, what is the purpose of an ambient temperature sensor?
How does the ambient temperature sensor ( ATS ) work?
The ambient temperature sensor (ATS) monitors the air temperature outside of the vehicle. The EATC compares these values and makes output decisions based on the difference of these air temperatures.
What to do if your ambient temperature sensor is not working?
1. The AC auto mode will not work Most modern vehicles have an auto AC setting that will allow the vehicle to automatically set and regulate the temperature. The AC system will simply read the ambient and cabin temperature sensors data and continuously cycle the AC system on and off as required to keep the cabin cool.
How are air temperature sensors used in cars?
Use a multimeter and verify the manufacturer’s specifications (~ 220-240 ohms at 70°-80° F), to test this sensor for proper resistance. Automotive air conditioning systems use NTC sensors to monitor air temperature. The In-Car Temperature sensor (ICTS) is an NTC that monitors the air temperature of the passenger compartment.
What is the function of the ambient temperature sensor?
It is the job of the ambient temperature sensor to measure the external temperature of the vehicle as a reference point for the computer to make calculations. The computer will continuously monitor the signal from the ambient temperature sensor and make automatic adjustments as needed to maintain cabin temperature.
What are the symptoms of a bad intake air temperature sensor?
Another symptom of a bad or defective air charge temperature sensor is difficulty starting in cold conditions. The air charge temperature sensor sends a signal to the computer during cold conditions that allow the computer to provide additional fuel required during cold starts.
Where is the ambient air temperature sensor located?
The ambient temperature sensor (switch) is located either behind the front grille or in the front bumper. Its only job is to monitor air temperature (which it does through increasing/decreasing resistance in response to temperature fluctuations).
What is an ambient air temperature sensor?
Ambient Air Temperature Sensor. The ambient (ATC) or outside air temperature sensor is an ( NTC ) negative temperature coefficient sensor that informs the semiautomatic/automatic temperature control system of outside air temperature. The NTC sensor’s resistance decreases as the outside air temperature increases.

What are the sensors in the air conditioner?
Sensors include but may not be limited to: humidity sensors. The ambient temperature sensor is usually placed in the grill or on a bracket in front of the AC condenser allowing it to communicate the ambient or actual external temperature.
What happens when the ambient temperature sensor goes bad?
As the ambient temperature sensor plays a direct role in the automated function of the AC system, when it is having a problem this may interfere with the system’s ability to cool the vehicle.
How does the NTC air temperature sensor work?
The NTC sensor’s resistance decreases as the outside air temperature increases. The computer uses this input, along with other in-car temperature sensors, to control temperature and blower speed. When there’s a problem with this sensor, performance suffers, and the compressor’s clutch may not engage.
