The most common reasons a 2006 Mitsubishi Lancer 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 2006 Mitsubishi Lancer 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 throttle position sensor fails, the engine's computer tends to overcompensate with fuel, leading black exhaust coming from the tailpipe. There is a strong possibility of engine misfires, and the check engine light will come on.

Throttle position sensors can also develop "dead spots," or certain places along the throttle curve where it doesn't get a reading. When this happens, the above symptoms can occur but then stop when you further press or let off the gas pedal.

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 2006 Mitsubishi Lancer?

When faced with a non-functioning cruise control in a 2006 Mitsubishi Lancer, it's crucial to adopt a systematic diagnostic approach. Start by checking the cruise control fuse in the fuse box to ensure it hasn't blown, as this is a simple fix that can often resolve the issue. Next, inspect the cruise control switch on the steering wheel for any signs of damage or wear, as a malfunctioning switch can prevent the system from engaging. It's also important to examine the brake pedal switch, which should disengage the cruise control when pressed; ensure it is functioning correctly and not stuck. The vehicle speed sensor plays a vital role in maintaining speed, so verify that it is operational and accurately sending signals to the control module. Finally, using a diagnostic scanner to check for error codes can provide insights into any underlying issues affecting the cruise control system. By following these steps, you can effectively troubleshoot and potentially fix the cruise control problem in your Mitsubishi Lancer.

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

When dealing with cruise control issues in a 2006 Mitsubishi Lancer, it's essential to understand the common problems that may arise. One frequent culprit is a faulty cruise control switch, which can hinder the system's ability to engage or disengage properly. Additionally, a blown fuse can disrupt the electrical flow necessary for the cruise control to function, making it a straightforward issue to check and replace. Another potential problem is vacuum leaks within the cruise control system, which can prevent it from maintaining the desired speed. The speed sensor also plays a critical role; if it malfunctions, it can lead to inaccurate speed readings, causing the cruise control to behave erratically. Furthermore, the brake light switch is crucial, as it disengages the cruise control when the brake pedal is pressed; a faulty switch can prevent the system from activating. Lastly, issues with the throttle cable, such as fraying or stretching, can affect the cruise control's ability to maintain a constant speed. By understanding these common problems, DIYers can better diagnose and address the issues affecting their vehicle's cruise control system.

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

When it comes to the non-functioning cruise control in a 2006 Mitsubishi Lancer, understanding the urgency of the situation is crucial for maintaining both safety and driving comfort. While this issue may not pose an immediate threat to the vehicle's overall drivability, it can significantly detract from the driving experience, especially during long journeys where cruise control is particularly beneficial. Ignoring this problem could lead to increased frustration for the driver, as the convenience of maintaining a steady speed is lost. Moreover, neglecting the cruise control issue might indicate underlying mechanical problems that could worsen over time, potentially leading to more serious and costly repairs. Therefore, while it may not be as critical as addressing brake or engine issues, it is advisable to resolve the cruise control malfunction promptly to enhance your driving experience and prevent future complications.
