Lincoln MKT Ambient Air Temperature Sensor: A Guide for 2010-2019 Models
Is your Lincoln MKT's A/C acting strange or the outside temperature display wrong? It could be this simple sensor.
- A faulty sensor primarily affects the automatic climate control and the outside temperature display.
- Symptoms include incorrect temperature readings, poor A/C performance on 'Auto', and a possible Check Engine Light.
- This is an easy and inexpensive DIY replacement, typically located behind the front grille.
- No recalls are currently active for this specific part on the 2010-2019 Lincoln MKT.
Is Your MKT's A/C or Temperature Display Acting Up?
If you've noticed the automatic climate control in your Lincoln MKT isn't keeping the cabin comfortable, or the temperature on your dashboard seems stuck or wildly inaccurate, a failing ambient air temperature sensor is a likely culprit. This sensor lives a tough life at the front of the vehicle, where it's exposed to the elements and road debris. Fortunately, replacing it is a simple and affordable DIY job.
Symptoms of a Failing Sensor
A bad ambient air temperature sensor will usually make itself known through a few distinct symptoms. You might experience one or all of the following:
- Incorrect Outside Temperature Reading: The display on your dashboard might show a temperature that is obviously wrong, like showing 35°F on a hot summer day.
- Automatic Climate Control Malfunctions: The 'Auto' setting on your A/C and heat may not work correctly. The system might blow warm air when it should be cooling or fail to adjust fan speed properly because it's getting bad information about the outside temperature.
- A/C Compressor Won't Turn On: In some cases, if the sensor incorrectly reports a freezing temperature outside, the vehicle's computer may prevent the A/C compressor from engaging to prevent damage.
- Check Engine Light: A failed sensor can trigger a Check Engine Light and store a diagnostic trouble code in the vehicle's computer.
A Note on Location and Damage
The ambient air temperature sensor on the Lincoln MKT is typically located behind the front grille, mounted to the radiator support. Because of this forward-facing position, it is vulnerable to damage from minor front-end collisions, road debris, and even automatic car washes. If your sensor has suddenly failed, it's worth checking for any physical damage.
Choosing the Right Aftermarket Sensor
You don't need to buy the most expensive sensor to get your MKT's A/C working correctly again. For a simple part like this, many aftermarket brands offer reliable quality at a great price. Here’s a breakdown of the brands available:
- OEM-Equivalent (Motorcraft): Motorcraft is Ford's official parts brand and the original part manufacturer. It offers a guaranteed fit and performance, but it is also the most expensive option.
- Reputable Aftermarket (Dorman, Standard Ignition): Brands like Dorman and Standard Motor Products (SMP) are well-known in the industry. They specialize in producing replacement parts that meet or exceed original specifications and are a trusted choice for both professional mechanics and DIYers.
- Value-Oriented (Holstein, URO Parts): Holstein and URO Parts provide functional replacements at a very competitive price. While sometimes perceived as lower-tier, they often provide good value for less critical components like this sensor and typically come with a warranty.
- Economy Brands (Skyward, True Tech): These brands represent the most budget-friendly options. For a simple sensor, they can be a cost-effective solution to get the job done.
Pro Tip: Check the Connector
Before ordering, it's always a good idea to visually inspect the sensor and its electrical connector on your vehicle. While rare, running changes can occur. Ensure the new part's connector matches the one on your MKT's wiring harness.
