The most common reasons a 2004 Honda S2000 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 2004 Honda S2000 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.

If the cruise control refuses to turn on at all, the actuator could be at fault. Likewise, if the cruise control stays on but does not maintain a consistent speed, the problem could be a bad actuator. In extreme cases, a malfunctioning actuator could cause the throttle to stick and prevent the vehicle from slowing down. These symptoms may point to a bad actuator. They may also point to other problems with the cruise control and related systems.

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.

A faulty cruise control module will simply result in deactivation of cruise control settings. This is because a detected error in the cruise control system could lead to hazardous driving conditions, so the module will be disabled, and the cruise control system warning light will be displayed. This will be a different message depending on make and model, and a warning light or message may be displayed on the driver instrument cluster.

What are the initial diagnostic steps to troubleshoot the non-functioning cruise control in a 2004 Honda S2000?

When troubleshooting the non-functioning cruise control in your 2004 Honda S2000, it's essential to start with a systematic diagnostic approach. Begin by ensuring that the cruise control feature is activated correctly; sometimes, the simplest issues can be overlooked. Next, check for any blown fuses, as a faulty fuse can disrupt the cruise control system's functionality. To locate the fuse box, refer to your vehicle's manual, which will guide you to the correct location. By following these initial steps, you can effectively narrow down the potential causes of the problem and determine whether further investigation or repairs are necessary. This methodical approach not only saves time but also empowers you to tackle the issue with confidence.

What are the common problems that could cause the cruise control to stop working in a 2004 Honda S2000?

When troubleshooting cruise control issues in a 2004 Honda S2000, it's essential to understand the common problems that may be at play. One frequent culprit is a faulty cruise control switch, which can hinder the system's ability to engage or disengage as intended. Additionally, a blown fuse within the cruise control circuit can disrupt functionality, rendering the system inoperative. Another potential issue is vacuum leaks, which can interfere with the system's operation by affecting the pressure needed for proper engagement. A defective speed sensor may also be responsible, as it plays a crucial role in maintaining the set speed. Lastly, problems with the brake light switch can prevent the cruise control from functioning correctly, as this switch is integral to the system's safety features. If you encounter issues with your cruise control, it's advisable to conduct a thorough inspection of these components to identify and resolve the underlying problem effectively.

How urgent is it to address the non-functioning cruise control in a 2004 Honda S2000?

When it comes to the non-functioning cruise control in a 2004 Honda S2000, understanding the urgency of the situation is crucial for any DIY enthusiast. While the immediate safety of the vehicle may not be compromised, neglecting this issue can lead to a less enjoyable driving experience, particularly on long trips where maintaining a steady speed is beneficial. A malfunctioning cruise control system can also indicate underlying electrical problems that, if left unaddressed, may escalate into more significant repairs down the line. Therefore, it is wise to investigate the cause of the malfunction sooner rather than later. By doing so, you not only restore the convenience of this feature but also potentially prevent further complications that could affect the vehicle's overall performance. Taking the initiative to diagnose and repair the cruise control system can enhance your driving comfort and ensure that your Honda S2000 remains in optimal condition for the road ahead.
