The most common reasons a 2019 Toyota Tacoma 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.

How much does it cost to fix a 2019 Toyota Tacoma 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 are the initial diagnostic steps to troubleshoot the non-functioning cruise control in a 2019 Toyota Tacoma?

When troubleshooting the non-functioning cruise control in a 2019 Toyota Tacoma, it's crucial to follow a structured diagnostic approach that prioritizes simpler checks before delving into more complex issues. Begin by inspecting the cruise control fuse located in the fuse box, as a blown fuse can easily disrupt the system's operation. Next, assess the cruise control buttons on the steering wheel to ensure they are not stuck or damaged, which could prevent the system from engaging. The vehicle speed sensor is another vital component; confirm its proper functioning since the cruise control system depends on accurate speed readings to operate effectively. Additionally, check the brake pedal switch, which is designed to disengage the cruise control when pressed; any malfunction here can keep the system inactive. Utilizing a diagnostic scanner to check for error codes can provide valuable insights into potential problems. Lastly, examine the cruise control module for any signs of damage and ensure that the vehicle is traveling at the minimum speed required for activation. By systematically following these steps, you can effectively diagnose and resolve issues with your Tacoma's cruise control system.

What are the common problems that could cause the cruise control to stop working in a 2019 Toyota Tacoma?

When your 2019 Toyota Tacoma's cruise control stops functioning, it can be frustrating, but understanding the common problems can help you diagnose the issue. One frequent culprit is a faulty brake light switch, which is crucial for the cruise control system as it disengages when the brake pedal is pressed. If this switch is malfunctioning, it may prevent the cruise control from engaging altogether. Another potential issue is related to the speed sensor; if this component is not accurately relaying speed information, the cruise control may fail to maintain a constant speed. Additionally, a blown fuse in the cruise control circuit can disrupt the system's operation, making it essential to check and replace any damaged fuses. Problems with the throttle actuator, which regulates engine speed, can also hinder the cruise control's performance, as can a malfunctioning cruise control module that controls the entire system. By systematically checking these components, you can identify and potentially resolve the cruise control issues in your Tacoma, making it a manageable DIY project.

How urgent is it to address the malfunctioning cruise control in my 2019 Toyota Tacoma?

When it comes to the malfunctioning cruise control in your 2019 Toyota Tacoma, the urgency of addressing the issue cannot be overstated. Cruise control is designed to enhance your driving experience by maintaining a steady speed, but when it fails, it can lead to unpredictable vehicle behavior, such as sudden acceleration or deceleration. This unpredictability poses a significant safety risk not only to you but also to other road users. Moreover, neglecting this malfunction can exacerbate the problem, potentially leading to more extensive damage to your vehicle's systems, which could result in costly repairs down the line. Therefore, prioritizing the diagnosis and repair of your cruise control system is essential for ensuring your safety and maintaining the overall performance of your Tacoma. Taking prompt action will not only enhance your driving comfort but also safeguard against future complications.
