The most common reasons a 2012 Lincoln MKT cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.
  • Sensor: A faulty or malfunctioning sensor can lead to incorrect readings, causing issues with engine performance or other systems relying on accurate data.
  • Control Module: A faulty control module can lead to erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
  • Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent throttle response.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2012 Lincoln MKT cruise control isn't working?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

When the throttle position sensor fails, the engine's computer tends to overcompensate with fuel, leading black exhaust coming from the tailpipe. There is a strong possibility of engine misfires, and the check engine light will come on.

Throttle position sensors can also develop "dead spots," or certain places along the throttle curve where it doesn't get a reading. When this happens, the above symptoms can occur but then stop when you further press or let off the gas pedal.

When the vehicle speed sensor fails or the wiring harness prevents signal transmission, the speedometer is the first thing that will stop functioning properly. This can be an intermittent issue where the speedometer only works occasionally, the speedometer may cease all function, or the speedometer may read erratically or incorrectly. Also, the traction control and anti lock brake warning lights specific to each vehicle may be illuminated, depending on the design of those systems. You may notice the vehicle hesitate to accelerate, cruise control will not function properly, and the vehicle may not shift properly through all of the gears.

In the event that a wheel speed sensor fails, the ABS, traction control system (TCS) and manufacturer specific stability control system lights will illuminate, informing the driver that the systems are disabled. The vehicle will be more prone to tire slip, and normal driving patterns may need to be adjusted to correct for the loss of computer control. On older vehicle's, the speedometer can be affected, causing illumination of the check engine light as well.

What are the initial diagnostic steps to troubleshoot the non-functional cruise control in a 2012 Lincoln MKT?

When faced with a non-functional cruise control in your 2012 Lincoln MKT, it's important to adopt a systematic diagnostic approach. Begin by checking the cruise control fuse located in the vehicle's fuse box, as a blown fuse can often be the simplest fix. Next, inspect the cruise control buttons on the steering wheel to ensure they are not stuck or damaged, as this can prevent the system from engaging. Following this, examine the speed sensors, which are vital for cruise control operation; any malfunction here could disrupt functionality. Utilizing a diagnostic scanner to check for error codes can provide further insights into potential issues within the cruise control system. Additionally, verify that the brake lights are operational, since faulty brake lights can inadvertently disengage the cruise control. Lastly, if your vehicle employs a vacuum-based cruise control system, inspect the vacuum lines for leaks or damage that could hinder performance. By methodically working through these steps, you can effectively diagnose and potentially resolve the cruise control issue in your Lincoln MKT.

What are the common problems that could cause the cruise control to stop working in a 2012 Lincoln MKT?

When dealing with cruise control issues in a 2012 Lincoln MKT, it's essential to understand the common problems that may be at play. One frequent culprit is a failed control module, sensor, or switch, which can disrupt the system's functionality. Additionally, throttle actuation problems can prevent the cruise control from engaging properly. It's also worth checking for a blown fuse, as well as inspecting the brake light and brake switch, since these components are integral to the cruise control system's operation. Furthermore, if the check engine light is illuminated or if there are other engine-related issues, these could also hinder the cruise control from working effectively. For those who prefer a DIY approach, starting with these common issues can help in diagnosing the problem before seeking professional assistance.

How urgent is it to address the non-functioning cruise control in a 2012 Lincoln MKT?

Addressing a non-functioning cruise control in a 2012 Lincoln MKT is more urgent than it may initially seem. While it might not present an immediate emergency, the implications of ignoring this issue can be significant. A malfunctioning cruise control system often signals deeper problems within the vehicle's electrical system or sensors, which, if left unchecked, could escalate into more severe mechanical failures. Moreover, the absence of cruise control can lead to increased driver fatigue during long trips, as maintaining a constant speed becomes more labor-intensive. This is particularly concerning on highways, where cruise control is frequently utilized for comfort and efficiency. By addressing the malfunction promptly, you not only enhance your driving experience but also mitigate potential safety risks and avoid costly repairs down the line. Therefore, if you notice any irregularities with your cruise control, it is advisable to investigate the issue sooner rather than later, ensuring your vehicle remains safe and reliable on the road.
