When the ambient temperature sensor fails, the system does not have a reference point from which to base it’s automatic calculations and the setting will not work. 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. Most modern vehicles have an auto AC setting that will allow the vehicle to automatically set and regulate the temperature.

When the ambient temperature sensor fails, there will usually be a few symptoms that may alert the driver that a problem with the sensor has occurred and it should be inspected or replaced if needed. The computer will continuously monitor the signal from the ambient temperature sensor and make automatic adjustments as needed to maintain cabin temperature. 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. For this reason, it is important for the system to be aware of the temperature of the environment that the vehicle is in. Vehicles in hot or cold extremes will require significantly more effort from the HVAC system to both cool and heat the cabin of the vehicle. One of the primary sensors that plays a key role in the operation of the AC system is the ambient temperature sensor, also commonly known as the ambient temperature sensor switch. They are able to do this by using a series of sensors that work together to activate and regulate the AC system. Modern vehicles are equipped with sophisticated heating and air conditioning systems that are highly efficient in achieving and maintaining comfortable cabin temperatures for the passengers.
