Resetting the ambient air temperature sensor in your car is not as complicated as it may seem. All you need is the right tools and materials, and you’re good to go. Just follow the steps outlined in this post, and you’ll have your sensor reset in no time.
Steps To Reset Ambient Air Temperature Sensor
Automobiles are equipped with a vast array of sensors tailored to keep the driver informed about a variety of vehicle features. One such sensor is the ambient air temperature sensor, which allows you to monitor the temperature outside your car.
However, some situations might cause your car’s ambient air temperature sensor to malfunction, preventing it from giving accurate readings. In that case, resetting the sensor might be an effective solution.
Step 1: Turn Off Your Car’s Engine
The first step is to ensure that your car’s engine is switched off. Turning off your car’s engine is wise because resetting the ambient air temperature sensor necessitates electrical contact. Turning off your engine reduces the chance of electrical accidents.
Step 2: Disconnect The Negative Battery Cable
After making sure that your car’s engine is switched off, disconnect the negative battery cable with a wrench. Confirm that you’ve disconnected the negative battery cable, as doing this makes your car’s electrical system non-functional.
Step 3: Wait For A Few Minutes
Waiting for a few minutes is a necessary step before resetting your car’s ambient air temperature sensor. Waiting gives the car’s electrical system time to discharge any stored electricity that might be in the vehicle’s sensors.
Step 4: Reconnect The Negative Battery Cable
Reconnect the negative battery cable with a wrench once you have waited for a few minutes. Reconnect it firmly to enable proper electrical contact. Ensure that the negative battery cable is reconnected to its initial position.
Step 5: Start Your Engine
Finally, start your car’s engine to verify that you’ve reset the ambient air temperature sensor. After resetting the sensor, go through your car’s temperature control and check that your vehicle is providing accurate temperature readings.
You can quickly reset your car’s ambient air temperature sensor by following these five steps. Furthermore, you can always repeat these instructions again if necessary.
