The most common reasons a 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.

How much does it cost to fix a 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.

Troubleshooting Cruise Control Issues in a Honda S2000

When troubleshooting cruise control issues in your Honda S2000, begin by checking the cruise control light on your dashboard. If it fails to illuminate when you engage the system, this could indicate a deeper problem. Next, inspect the 14P connector linked to the cruise control unit; ensure that the terminals are clean and securely connected, as bent or corroded terminals can disrupt functionality. If these initial checks do not resolve the issue, consider examining the cruise control actuator and control module, as these components are common failure points. Simple fixes, such as replacing a faulty connector or cleaning terminals, can often be done at minimal cost, making them ideal first steps for DIY repairs. If the problem persists after these checks, it may be time to consult a professional for more complex diagnostics, but many owners have successfully resolved issues with straightforward, inexpensive methods. By following this structured approach, you can effectively address cruise control problems and restore functionality to your Honda S2000.

What Are the Common Problems with Cruise Control in a Honda S2000?

When dealing with cruise control issues in a Honda S2000, it's essential to understand the common problems that can arise. One frequent culprit is the control module, which can fail and prevent the cruise control from functioning properly. Additionally, issues with sensors or switches can disrupt the system's operation, leading to malfunctions. For instance, a faulty throttle position sensor, particularly in models like the 2003 Honda S2000, can cause the engine's computer to mismanage fuel delivery, resulting in noticeable black exhaust. If you notice that the cruise control light is on but the system does not engage, this could indicate a deeper issue within the cruise control system itself. A practical step in troubleshooting is to inspect the cruise control module located under the dash, ensuring it has power and proper connections, as a failed module is a common reason for cruise control failures. By focusing on these specific components, DIY enthusiasts can effectively diagnose and address cruise control problems in their Honda S2000.

Why is the Cruise Control Not Working in a Honda S2000?

When your Honda S2000's cruise control stops functioning, it's crucial to address the issue promptly to ensure both your safety and the longevity of your vehicle. Common culprits include a failed cruise control module, which is often the primary reason for malfunction. Additionally, sensor or switch problems can disrupt the system's operation, while throttle actuation issues may also play a role. To effectively troubleshoot, start by inspecting the cruise control module located under the dash; check for power and secure connections. It's equally important to examine the connectors and terminals for any signs of damage, such as bent, loose, or corroded parts, as these can significantly impact functionality. Neglecting these symptoms not only compromises your driving experience but could also lead to more severe mechanical issues down the line, making it essential to act swiftly and address any problems as they arise.
