The most common reasons a 2006 Mitsubishi Eclipse 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 2006 Mitsubishi Eclipse 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-functional cruise control in a 2006 Mitsubishi Eclipse?

When troubleshooting the non-functional cruise control in a 2006 Mitsubishi Eclipse, it's important to follow a structured diagnostic approach that prioritizes simpler checks before delving into more complex issues. Begin by inspecting the cruise control fuse, as a blown fuse is a common culprit that can easily be replaced. Next, assess the cruise control switch on the steering wheel; if this switch is malfunctioning, it may prevent the system from engaging properly. It's also vital to check the brake lights, since a defective brake light switch can inadvertently disable the cruise control system. Additionally, ensure that the vehicle speed sensor is functioning correctly, as it plays a crucial role in relaying speed information to the cruise control module. Lastly, consider scanning the vehicle's onboard computer for any error codes that may indicate specific problems within the cruise control system. By systematically addressing these areas, you can effectively identify and resolve the issues affecting your cruise control, leading to a more enjoyable driving experience.

What are the common problems that could cause the cruise control to stop working in a 2006 Mitsubishi Eclipse?

When the cruise control in your 2006 Mitsubishi Eclipse ceases to function, it can be frustrating, but understanding the common problems can guide you in troubleshooting the issue. One of the first things to check is the cruise control switch, as a faulty switch can prevent the system from engaging. Additionally, inspect the fuses related to the cruise control system; a blown fuse can easily disrupt its operation. Another critical area to examine is the vacuum system, as any leaks can interfere with the cruise control's ability to maintain speed. The speed sensor is also vital; if it is defective, the cruise control may struggle to keep a constant speed. Furthermore, issues with the brake light switch can prevent the cruise control from activating, as the system is designed to disengage when the brakes are applied. Lastly, don’t overlook the throttle cable, as any malfunction here can directly impact the cruise control's performance. By systematically checking these components, you can identify and resolve the issues affecting your cruise control system.

How urgent is it to address the non-functioning cruise control in a 2006 Mitsubishi Eclipse?

Addressing the non-functioning cruise control in a 2006 Mitsubishi Eclipse is crucial due to the immediate safety risks it poses. A malfunctioning system can lead to erratic speed changes, increasing the likelihood of accidents and creating unsafe driving conditions. Moreover, cruise control is designed to enhance comfort during long drives, and its failure can lead to increased driver fatigue, detracting from the overall driving experience. Additionally, neglecting this issue may indicate deeper mechanical problems within the vehicle, which could escalate into more significant and costly repairs if not addressed promptly. Therefore, it is essential to prioritize the repair of the cruise control system to ensure both safety and comfort while driving, as well as to prevent further complications.
