THE IMPORTANCE OF An Ambient Air Temperature Sensor Replacement

What is an ambient air temperature sensor and how does it work?

An ambient air temperature sensor is a device that measures the temperature outside of your vehicle. It is usually mounted in the front bumper or just inside of the grille, ahead of the radiator.

Information from the ambient air temperature sensor (along with that of a sensor inside the vehicle) is relayed to a computer module. The computer uses that information to make adjustments to the heating and air conditioning system to automatically heat or cool the cabin. The sensor also allows you to see the temperature outside.

On some vehicles, the Engine Control Module might also use the data from the ambient air temperature sensor to help control the air/fuel mixture going into the engine for maximum efficiency.

COMMON SYMPTOMS

How do I know if my vehicle needs a new ambient air temperature sensor?

If the ambient air temperature sensor fails, you might notice one or more of several symptoms. For instance, if your vehicle is equipped with an air conditioning system that adjusts automatically to regulate the cabin temperature, you might find that the AC does not cool consistently. Or the automatic mode might not work at all. And if you are used to seeing the temperature displayed on the dashboard, you might find that it does not match the actual temperature outside.

Other signs that the ambient air temperature sensor is bad might include:

Reduction in fuel economy

Poor engine performance

The check engine light comes on

FREQUENCY OF INSPECTION

How does a technician perform An Ambient Air Temperature Sensor Replacement ?

To replace the ambient air temperature sensor on your vehicle, a technician will need to remove any splash guards, grilles, or other body components necessary to gain access to the sensor. The negative battery terminal will also be disconnected.

From there, the procedure to replace the sensor is fairly simple. The fasteners that hold the sensor in place are removed, the sensor is dislodged, and the wires that connect to the sensor are unplugged before a new sensor is plugged in and fastened in place.

Once the body components are reattached and the battery is reconnected, the technician will likely run or test drive your vehicle to verify that the AC system and temperature display are working properly.



Other Questions Customers Ask

Will the air conditioning still work with a broken ambient air temperature sensor?
Yes, in most cases, your air conditioning will still work with a faulty ambient air temperature sensor. What might not work is the “Auto” mode of the climate control system. The automatic mode is what allows you to set the temperature inside your vehicle to a desired level while the vehicle's computer determines how much heat or air conditioning to use to reach that setpoint. The process is much like the thermostat in your house.
Where is the ambient air temperature sensor located?
The ambient air temperature sensor is located near the front of your vehicle. It is often mounted behind the grille ahead of the radiator where it will detect the outside air without influence from the heat of your engine. It might also be mounted inside of the front bumper.
How do I test my ambient air temperature sensor?
To test an ambient air temperature sensor, a qualified technician may have to connect a diagnostic computer or scan tool to your vehicle to read the sensor feedback. After connecting the scan tool, the technician may then apply heat to the temperature sensor with a heat gun or hair dryer and confirm the rising temperature readings from the sensor.
