The most common reasons a 2020 Ford F-150 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 2020 Ford F-150 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 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.

The cruise control switch can cause complete failure of the cruise control feature, but in a lucky scenario only partial functionality will be lost. This means that the cruise control may come on, but that it will not increase in speed automatically, or the cancel button does not work leading the driver to cancel cruise control with the foot brake. In some vehicles, the cruise control light may illuminate, or a warning message may be displayed due to lack of functionality.

What steps should I take to diagnose the non-functioning cruise control in my 2020 Ford F-150?

When diagnosing the non-functioning cruise control in your 2020 Ford F-150, it's essential to adopt a systematic approach that begins with the simplest solutions before progressing to more complex diagnostics. Start by checking the fuse associated with the cruise control system, as a blown fuse is a common and easily fixable issue. Next, inspect the wiring for any signs of damage or loose connections, as these can disrupt the system's functionality. After ensuring the wiring is intact, test the cruise control buttons on your steering wheel to confirm they are operational; a malfunctioning button can often be the culprit. If these initial checks do not resolve the issue, utilize an OBD-II scanner to identify any error codes that may indicate specific problems within the cruise control system. Additionally, verify that the speed sensors are functioning correctly, as they play a crucial role in the operation of cruise control. If you still cannot determine the cause of the malfunction, it may be time to consult a qualified mechanic or dealership, as they possess the expertise and specialized tools necessary for diagnosing more complex issues. By following this structured diagnostic approach, you can effectively identify and address the problem with your cruise control system.

What are the common problems that could cause the cruise control to stop working in a 2020 Ford F-150?

When troubleshooting the cruise control system in a 2020 Ford F-150, it's essential to understand the common problems that may lead to its failure. One of the primary culprits is a faulty brake pedal switch, which is designed to deactivate the cruise control when the brake is pressed; if this switch malfunctions, it can prevent the system from engaging. Additionally, issues with the speed sensor can disrupt the cruise control's functionality, as the system relies on accurate speed readings to maintain the desired speed. Another potential issue is a blown fuse within the cruise control circuit, which can easily be checked and replaced if necessary. Furthermore, a malfunctioning cruise control module may also be at fault, requiring replacement to restore proper operation. Lastly, problems with the throttle control system, such as a faulty throttle position sensor, can hinder the cruise control's ability to maintain speed. By identifying and addressing these common issues, you can effectively troubleshoot and potentially resolve the cruise control problems in your Ford F-150.

How urgent is it to address the malfunctioning cruise control in my 2020 Ford F-150?

When it comes to your 2020 Ford F-150, addressing a malfunctioning cruise control system is not just a matter of convenience; it is a critical safety concern that requires immediate attention. A malfunctioning cruise control can lead to erratic vehicle behavior, such as unexpected acceleration or deceleration, which poses significant risks, especially on highways or busy roads. Moreover, these issues may signal deeper problems within the vehicle's electronic systems or sensors, potentially affecting other essential functions and compromising overall vehicle safety. Ignoring these symptoms can also lead to decreased fuel efficiency and may result in costly repairs down the line, as prolonged neglect can cause damage to the engine or transmission. Therefore, it is crucial to prioritize a thorough inspection and repair of the cruise control system by a qualified mechanic or authorized service center. Taking prompt action not only ensures your safety but also protects the integrity and performance of your vehicle in the long run.
