The most common reasons a 2003 Mitsubishi Outlander 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 2003 Mitsubishi Outlander 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.

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 2003 Mitsubishi Outlander?

To effectively diagnose the non-functioning cruise control in a 2003 Mitsubishi Outlander, 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, evaluate the cruise control switch to ensure it is operational; a malfunctioning switch can prevent the system from engaging. Following this, examine the brake pedal switch, which is critical for the cruise control's functionality; if this switch is defective, it will disable the system. Additionally, check the speed sensor, as it provides essential data for the cruise control to function correctly; any faults here can lead to operational issues. If your vehicle uses vacuum lines for the cruise control, inspect these for leaks or damage, as such issues can disrupt the system's performance. Finally, utilize a diagnostic scanner to identify any error codes that may indicate specific problems within the cruise control system. By following this structured diagnostic approach, you can efficiently identify and resolve the issues affecting your cruise control.

What are the common problems that could cause the cruise control to stop working in a 2003 Mitsubishi Outlander?

When dealing with a malfunctioning cruise control system in a 2003 Mitsubishi Outlander, it's crucial to understand the common problems that may be at play. One of the primary culprits could be a faulty cruise control switch, which may prevent the system from engaging properly. Additionally, a blown fuse can disrupt the electrical flow necessary for the cruise control to function, making it another potential issue to check. Vacuum leaks are also a frequent cause of cruise control failure, as they can interfere with the system's ability to maintain speed. Furthermore, a defective speed sensor can lead to erratic behavior or complete disengagement of the cruise control. It's also important to consider the brake light switch; if it malfunctions, it may inadvertently signal the system to deactivate. Lastly, issues with the throttle cable can hinder the cruise control's performance, affecting its ability to sustain speed. By systematically examining these components, DIYers can effectively diagnose and address the cruise control problems in their Outlander.

How urgent is it to address the non-functioning cruise control in a 2003 Mitsubishi Outlander?

Addressing the non-functioning cruise control in a 2003 Mitsubishi Outlander is crucial for several reasons that highlight 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 on the road. This unpredictability can be particularly dangerous during long drives where maintaining a steady speed is essential for safe navigation. Additionally, the comfort and convenience that cruise control provides cannot be overlooked. It significantly reduces driver fatigue during extended trips, allowing for a more enjoyable driving experience. Lastly, from a financial perspective, neglecting this issue could adversely affect the vehicle's resale value. Potential buyers are often deterred by vehicles with non-functional features, making it imperative to keep all systems, including cruise control, in optimal working condition. Therefore, while it may not seem like an immediate emergency, addressing the non-functioning cruise control should be a priority to ensure safety, enhance driving comfort, and protect the vehicle's value.
