  • 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 2011 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 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 cruise control issue in a 2011 Mitsubishi Lancer?

When diagnosing a cruise control issue in a 2011 Mitsubishi Lancer, it's crucial to follow a structured diagnostic approach that prioritizes simpler checks before delving into more complex solutions. Begin by inspecting the cruise control fuse, as a blown fuse can easily disrupt the system's functionality. Next, verify that the cruise control buttons on the steering wheel are operational and not stuck, as this can prevent the system from engaging. After that, examine the speed sensors, which are essential for the cruise control's operation; any malfunction here can lead to significant issues. Utilizing a diagnostic scanner to check for error codes can provide valuable insights into the underlying problem. Additionally, inspect the vacuum lines for any leaks, as these are critical for the cruise control's performance. Testing the cruise control module is also vital, as a faulty module can impede communication within the system. Lastly, ensure that all wiring connections are secure and undamaged, as loose or broken connections can result in intermittent issues. By methodically following these steps, you can effectively diagnose and resolve the cruise control problem in your Mitsubishi Lancer, restoring its functionality and enhancing your driving experience.

What are the common problems that could cause the cruise control to stop working in a 2011 Mitsubishi Lancer?

When troubleshooting cruise control issues in a 2011 Mitsubishi Lancer, it's essential to consider several common problems that could be at play. One of the first areas to check is the brake pedal switch, as a faulty switch can prevent the cruise control from engaging, since it is designed to deactivate when the brake is pressed. Additionally, the speed sensor plays a crucial role in maintaining a constant speed; if it malfunctions, the cruise control may fail to operate correctly. Another potential issue is a blown fuse within the cruise control system, which can completely disable its functionality. Furthermore, the cruise control module itself may be defective, leading to operational failures. Lastly, don't overlook the possibility of vacuum leaks in the engine, as these can disrupt the system's ability to maintain speed. By systematically examining these components, DIYers can often identify and resolve the underlying issues affecting their cruise control system.

How urgent is it to address the non-functioning cruise control in a 2011 Mitsubishi Lancer?

Addressing the non-functioning cruise control in a 2011 Mitsubishi Lancer is crucial for several reasons that underscore the urgency of the situation. First and foremost, safety is a primary concern; a malfunctioning cruise control system can lead to erratic speed changes, increasing the risk of accidents, especially during long drives or highway travel. Additionally, the comfort and convenience that cruise control offers are significant, as it reduces driver fatigue on extended journeys. Restoring this functionality not only enhances the driving experience but also contributes to overall road safety. Furthermore, neglecting this issue can adversely affect the vehicle's resale value. A well-maintained car, with all systems functioning properly, is more appealing to potential buyers. Therefore, while it may not seem like an immediate emergency, addressing the non-functioning cruise control promptly is essential to ensure safety, enhance comfort, and protect the vehicle's value.
