Ford Taurus Ambient Air Temperature Sensor Guide (2014-2019)
Is your Taurus's A/C acting up or showing the wrong outside temperature? Your ambient air temperature sensor might be the culprit.
- A bad sensor is the most common cause of an incorrect outside temperature display and automatic A/C problems on the 2014-2019 Taurus.
- This is an easy and inexpensive DIY repair that typically takes less than 30 minutes.
- Quality aftermarket brands like Dorman and Standard Ignition offer reliable alternatives to the more expensive OEM Motorcraft part.
- Always check the electrical connector for corrosion, as it can cause the same symptoms as a failed sensor.
Is Your Ford Taurus A/C or Temperature Display Acting Strange?
If the outside temperature reading on your 2014-2019 Ford Taurus dashboard is obviously wrong, or if your automatic climate control isn't working correctly, a bad ambient air temperature sensor is a likely cause. This small, inexpensive sensor plays a big role in both your comfort and your car's electronic systems. When it fails, it can cause confusing issues, but it's usually a simple and affordable fix.
Symptoms of a Failing Ambient Air Temperature Sensor
A bad sensor can cause several noticeable problems in your Taurus. Here’s what to look for:
- Incorrect Outside Temperature Display: The most common symptom is a temperature reading on your dash that is stuck or clearly wrong (e.g., showing 35°F on a hot day). If the sensor circuit is open, the display may even show a default low value like -40°F.
- Automatic Climate Control Malfunction: The 'Auto' setting for your A/C and heat may not work properly. The system relies on an accurate outside temperature to regulate cabin temperature, so a bad reading can cause it to blow hot air when it should be cold, or vice-versa.
- A/C Compressor Won't Engage: In some cases, a faulty sensor can prevent the A/C compressor from turning on at all, leaving you with no cold air. 🎬 See how a faulty sensor can disable your A/C system. This is a built-in protection to prevent system damage in what the car thinks are freezing conditions.
- Check Engine Light: A failing sensor can trigger a Check Engine Light. Common trouble codes include P0071, P0072, and P0073, which point to a problem with the sensor's circuit or performance. 🎬 Watch: How to test and fix a P0073 trouble code.
Don't Ignore a Faulty Sensor
While a bad ambient air temperature sensor won't stop you from driving, it can make your ride uncomfortable and may affect the defrost system's efficiency. In some Ford models, a bad sensor reading can also cause issues with heated mirrors or other systems.
Choosing the Right Aftermarket Sensor
For the 2014-2019 Taurus, you have several good options for replacement sensors without paying dealership prices. The original equipment (OEM) part is made by Motorcraft, but quality aftermarket brands offer reliable alternatives.
- Motorcraft: This is the OEM brand. It guarantees a perfect fit and original performance. If you prefer to stick with factory parts, this is your choice, though it's usually the most expensive.
- Dorman: A well-known aftermarket brand that produces direct-fit replacement parts. Dorman sensors are designed to match the original's function and are a reliable, cost-effective solution.
- Standard Ignition (SMP): Another trusted name in automotive electronics, Standard Ignition parts are known for quality and are used by many professional technicians. Their sensors undergo extensive testing to ensure performance.
- URO Parts: While often associated with European cars, URO Parts makes sensors for a wide range of vehicles. They are known for offering OE-quality parts at a competitive price, often with a good warranty.
Pro Tip: Check the Connector
The sensor is located in the front of the vehicle, often behind the grille, making it vulnerable to moisture and corrosion. Sometimes the sensor itself is fine, but the electrical connector is corroded. It's a good idea to inspect the connector when you replace the sensor. Some aftermarket kits even include a new connector pigtail for this reason.
