How to Reset Ambient Temperature Sensor Ford
If your Ford is equipped with an ambient temperature sensor, it’s located on the front of the vehicle near the grille. The sensor measures the air temperature around the vehicle and sends a signal to the climate control system to adjust accordingly. If you live in an area with extreme temperatures, or if you regularly take your Ford on long road trips, it’s important to know how to reset ambient temperature sensor.

How Do You Reset the Outside Temperature Sensor on a Ford F 150?
If your Ford F-150’s outside temperature sensor isn’t working properly, you can reset it yourself in just a few minutes. Here’s how:
1. Park your truck in a well-ventilated area and turn off the engine.
2. Remove the negative battery cable from the battery using a wrench. This will prevent any electrical shorts while you’re working on the sensor.
3. Locate the outside temperature sensor, which is usually located on or near the radiator support behind the grille.
It will be a small black box with wires running to it.
4. Unplug the connector from the sensor and use a small screwdriver or other tool to gently pry open the top of the housing. Be careful not to damage the wires inside.
5. Use a cotton swab or other soft object to clean any dirt or debris from around the sensing element inside the housing (this is what actually measures the temperature). Be sure not to touch this element directly, as it can be easily damaged.
How Do You Reset the Ambient Temperature Sensor on a Ford F150 2018?
If you have a Ford F-150 from the 2018 model year, then you may be wondering how to reset the ambient temperature sensor. This is a pretty straightforward process, but it’s still important to follow the steps carefully in order to avoid any potential issues. Here’s what you need to do:
1. Start by ensuring that the engine is off and the battery is disconnected. This will help to prevent any electrical damage while you’re working on the sensor.
2. Locate the ambient temperature sensor.
It’s located in front of the radiator, behind the grille.
3. Use a flathead screwdriver to remove the two screws that hold the sensor in place. Be careful not to lose them!
4. Carefully disconnect the wiring harness from the back of the sensor. Again, take care not to damage anything in this process.
5. At this point, you can remove and replace the old sensor with a new one if needed.
If not, simply reattach everything in reverse order – start with reconnecting the wiring harness, then screwing in place both screws (tighten them evenly), and finally reattachtingthe battery before starting up your engine as usual..
How Do I Calibrate My Ambient Temperature Sensor?
There are four main types of temperature sensors: thermocouples, RTDs, Thermistors, and ICs. Of these, RTDs and Thermistors are the most popular for ambient temperature sensing. Here we’ll focus on how to calibrate an RTD sensor.
As with any sensor calibration, you’ll need to first identify the accuracy desired from the sensor. For example, will 0.1°C be acceptable, or do you need 0.01°C? The level of accuracy will determine the amount of effort required for calibration as well as the number of data points that must be taken.
Let’s assume you’re working with a 3-wire RTD that has a resistance vs temperature curve like this one:

To calibrate such a sensor, you would need at least two reference points that bracket the expected operating temperature range. These can be provided by either fixed-point (ice and boiling water) or liquid-in-glass (mercury or alcohol) thermometers.
It’s generally best to use at least three reference points though, especially if your expected operating range is large (>100°C).
With your reference points in hand, measure the resistance of your RTD at each point and plot it on the resistance vs temperature curve like so:

As you can see from the plot above, there is a nonlinear relationship between resistance and temperature for this particular RTD (red dots), but a linear trendline (blue line) can still be fit to the data reasonably well. This linear trendline represents our calibrated sensor output over its entire specified range (-200 to 850°C in this case).
There are many ways to mathematically derive this linear trendline from your data points; one popular method is known as least squares regression analysis.
Why is My Car Reading the Wrong Outside Temperature?
There are a few reasons that your car might be reading the wrong outside temperature. One possibility is that the sensor that reads the temperature is not working correctly. Another possibility is that there is something blocking the sensor, such as dirt or insects.
If the sensor is blocked, it will not be able to accurately read the temperature. Finally, if your car’s computer system is not calibrated correctly, it could also be displaying the wrong temperature. If you suspect that one of these things is causing your car to read the wrong outside temperature, you should take it to a mechanic to have it checked out.

How to Reset Ambient Temperature Sensor Ford Explorer
If you have a Ford Explorer that needs the ambient temperature sensor reset, here are the steps you need to take. The process is actually quite simple and should only take a few minutes to complete.
First, locate the ambient temperature sensor.
It is located on the front of the vehicle, just behind the grille. Once you have found it, disconnect the electrical connector from the sensor.
Next, use a flathead screwdriver to remove the two screws that hold the sensor in place.
Be careful not to damage the surrounding area as you remove these screws.
With the screws removed, gently pull on the sensor until it comes free from its housing. You may need to wiggle it a bit to get it loose but be careful not to break anything in the process.
Once you have removed the old sensor, simply insert the new one into place and reattach both screws. Reconnect the electrical connector and you’re done! Your Ford Explorer’s ambient temperature sensor has now been successfully reset.
