How does an ambient air temperature sensor work?
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 happens when you change the O2 sensor?
The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle’s computer. The ECU then adjusts the air-to-fuel ratio to optimize the fuel combustion. Sometimes an O2 sensor fails, and you need to replace it.
Why is my ambient temperature sensor not working?
Everything that hits your grille while you are driving has a potential to hit this sensor if it is not properly protected. If the ambient temperature sensor failed due to issues with components surrounding it, those issues would need to be addressed before you waste your money and time in replacing it with a new one.
What should I do if my car sensor is not working?
The sensor and the computer will need a moment to communicate. Once they have established a connection with each other, your vehicle’s displays should be reading correctly. Allow your vehicle to warm up and then set it to a temperature that is lower or higher than the ambient temperature outside.
