What vehicles are most commonly affected by P0584?
P0584 is often reported in vehicles like the 2016 Ford F-150, 2015 Honda Accord, and 2014 Chevrolet Silverado. These models may have specific recalls or service bulletins related to the cruise control system.
How can I prevent P0584 from happening again?
Regular maintenance, such as checking electrical connections and switches for wear, can help prevent P0584. Additionally, ensuring that the vehicle’s software is up to date can mitigate potential issues.
What is P0584?
DTC P0584 refers to a malfunction in the cruise control system, specifically indicating that the cruise control switch input is not functioning as expected. This code can be triggered by various issues, including faulty wiring, a defective cruise control switch, or problems within the powertrain control module (PCM). It's essential to understand that while this code may not immediately affect your vehicle's drivability, it can lead to significant safety concerns. For example, in vehicles like the 2016 Ford F-150 and 2015 Honda Accord, drivers have reported that the cruise control system may not engage or disengage properly, leading to unpredictable vehicle speed. As a result, the driver might experience difficulty maintaining a steady speed, which poses risks on highways. If you notice this code, it’s advisable to address it promptly to avoid complications and ensure your cruise control system operates safely and effectively. Over time, ignoring the P0584 code can lead to additional wear on the engine and transmission systems due to inconsistent throttle input.

Symptoms
Common symptoms when P0584 is present:
- The check engine light illuminates, indicating a problem with the cruise control system.
- Cruise control fails to activate or deactivate, causing erratic speed control while driving, particularly on highways.
- Inconsistent engine performance, such as sudden acceleration or deceleration, especially when cruise control is engaged.
- Driver may experience difficulty maintaining a constant speed, leading to increased fuel consumption during highway driving.
- Unusual noises or clicking sounds from the steering column area when attempting to use cruise control.
Possible Causes
Most common causes of P0584 (ordered by frequency):
- The most common cause of the P0584 code is a faulty cruise control switch, which can account for approximately 40% of cases. This switch may wear out over time, leading to intermittent functionality.
- Another likely cause is damaged wiring or connectors in the cruise control circuit. This could be due to corrosion or physical damage, which can impede electrical signals.
- A third cause might be related to issues within the PCM itself, which can be less common but requires a thorough diagnosis to confirm.
- Less commonly, a malfunctioning throttle position sensor can also trigger this code, affecting the engine management system.
- In rare cases, software glitches in the vehicle's computer system can lead to false P0584 codes, necessitating a software update or reprogramming.
