The most common reasons a 2007 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.
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 2007 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 steps to diagnose the non-functioning cruise control in a 2007 Mitsubishi Eclipse?

To effectively diagnose the non-functioning cruise control in your 2007 Mitsubishi Eclipse, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the fuse associated with the cruise control system, as a blown fuse is a common and easily fixable issue. Next, examine the cruise control switch to ensure it is operational; a malfunctioning switch can prevent the system from engaging. Following this, check the brake pedal switch, which is crucial for disengaging the cruise control when brakes are applied; if this switch is faulty, it can disable the entire system. Additionally, test the vehicle speed sensor, as it is vital for the cruise control's functionality; a defective sensor can lead to significant issues. To further narrow down potential problems, utilize an OBD-II scanner to identify any error codes that may indicate specific faults within the cruise control system. If these steps do not resolve the issue, it may be necessary to consult a qualified mechanic who specializes in Mitsubishi vehicles for a more thorough diagnosis and repair. By following this structured diagnostic approach, you can efficiently identify and address the underlying causes of your cruise control malfunction.

What are the common problems that could cause the cruise control to stop working in a 2007 Mitsubishi Eclipse?

When dealing with a malfunctioning cruise control system in a 2007 Mitsubishi Eclipse, it's crucial to identify the common problems that may be at play. One frequent culprit is a faulty cruise control switch, which can hinder the system from engaging properly. Additionally, a blown fuse within the cruise control circuit can lead to a complete failure of the system, making it essential to check the fuses first. Another significant factor is the speed sensor; if this component is defective, it can disrupt the cruise control's ability to maintain a consistent speed. Vacuum leaks are also a concern, as they can affect the system's functionality by causing fluctuations in pressure. Furthermore, issues with the brake light switch can lead to unexpected disengagement of the cruise control, while a malfunctioning throttle cable may prevent the system from maintaining speed effectively. By understanding these common problems, DIYers can better diagnose and address the issues with their cruise control system, ensuring a smoother driving experience.

How urgent is it to address the non-functioning cruise control in a 2007 Mitsubishi Eclipse?

When it comes to the non-functioning cruise control in a 2007 Mitsubishi Eclipse, addressing the issue should not be overlooked, even if it may not seem as urgent as other mechanical problems. While the vehicle remains drivable, the absence of cruise control can significantly detract from the driving experience, especially during long journeys where maintaining a steady speed is beneficial. Ignoring this issue could lead to increased driver fatigue and frustration, particularly on highways where cruise control is most advantageous. Moreover, neglecting the cruise control problem could potentially escalate into more complex issues, resulting in higher repair costs down the line. Therefore, while it may not pose an immediate safety risk like brake or engine failures, timely attention to the cruise control system is essential for ensuring a comfortable and enjoyable driving experience, as well as preventing future complications.
