Ford Escape Ambient Air Temperature Sensor Guide (2007-2013)
Is your A/C acting up or showing a weird outside temperature? Your ambient air temperature sensor might be the problem.
- A bad sensor is the most likely cause for an incorrect outside temperature display and erratic automatic A/C performance.
- The sensor is located behind the front grille, making it an easy part to access and replace for a DIY repair.
- Aftermarket brands like Standard Ignition and Dorman offer a reliable and cost-effective alternative to the more expensive OEM Motorcraft part.
- After replacement, you may need to drive the vehicle for a few minutes or perform a reset procedure for the new sensor to read correctly.
Is Your Ford Escape's A/C or Temperature Display Acting Strange?
If your 2007-2013 Ford Escape is showing a wildly incorrect outside temperature, or if the automatic climate control isn't working properly, a faulty ambient air temperature sensor is a likely culprit. This small sensor plays a big role in both your comfort and the information your vehicle displays. When it fails, it can cause confusing issues, but it's usually a simple and inexpensive fix.
Common Failure Symptoms
🎬 Watch: A quick guide to common bad sensor symptoms.- Incorrect Temperature Display: The most obvious sign is the outside temperature reading on your dash being wrong, sometimes showing extreme values like -40°F or 150°F.
- A/C Not Working Correctly: The automatic climate control may not cool or heat the cabin properly because it's getting bad information about the outside air temperature. In some cases, the A/C compressor might not turn on at all.
- Check Engine Light: A failed sensor can trigger a Check Engine Light and store diagnostic trouble codes like P0073 (Ambient Air Temperature Sensor Circuit High).
Where is the Sensor Located on a 2007-2013 Escape?
On the 2007-2013 Ford Escape, the ambient air temperature sensor is typically located in the front of the vehicle, behind the grille. It is often mounted to the radiator support, where it can get a good reading of the outside air without being directly affected by engine heat. You can usually access it by looking through the grille or from underneath the front bumper area.
Choosing the Right Aftermarket Sensor
For a simple sensor like this, you don't always need to pay dealership prices for the OEM Motorcraft part. Several quality aftermarket brands offer reliable replacements at a much lower cost. Here’s a breakdown of your options:
OEM (Original Equipment Manufacturer)
- Motorcraft: This is the original Ford part. It guarantees a perfect fit and function, but it's also the most expensive option. For a non-critical sensor, the cost may not be justified for most owners.
Premium Aftermarket
- Standard Ignition (SMP) / True Tech: Often considered a top-tier aftermarket brand, Standard Ignition parts are known for their quality and reliability, often meeting or exceeding OEM specifications. They are a solid choice if you want high quality without the OEM price tag.
- Holstein / URO Parts: These brands are also known for producing quality components and offer a good balance between price and performance.
Value Aftermarket
- Dorman / Skyward: Dorman is a well-known brand that produces a huge range of affordable replacement parts. While some of their more complex parts can have mixed reviews, for a simple sensor like this, they offer a cost-effective solution that gets the job done.
Pro Tip: For this specific part on the Escape, a premium or even a value aftermarket brand is usually sufficient. The technology is simple, and brands like Standard Ignition or Dorman provide a reliable fix for a fraction of the OEM cost. The key is ensuring the part number matches your vehicle.
Cost of Replacing the Ambient Air Temperature Sensor
| Part Type | Price Range |
|---|---|
| New Aftermarket | $6.47 - $63.18 |
| New OEM (Motorcraft) | $30 - $70 (estimated) |
| Shop Labor | $50 - $100 |
