The most common reasons a 1996 Mitsubishi Galant 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 1996 Mitsubishi Galant 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.

If the cruise control refuses to turn on at all, the actuator could be at fault. Likewise, if the cruise control stays on but does not maintain a consistent speed, the problem could be a bad actuator. In extreme cases, a malfunctioning actuator could cause the throttle to stick and prevent the vehicle from slowing down. These symptoms may point to a bad actuator. They may also point to other problems with the cruise control and related systems.

What are the initial diagnostic steps to troubleshoot the non-functional cruise control in a 1996 Mitsubishi Galant?

When troubleshooting the non-functional cruise control in a 1996 Mitsubishi Galant, start with the simplest checks before moving on to more complex diagnostics. Begin by inspecting the fuse associated with the cruise control system; a blown fuse can easily disrupt functionality. Next, examine the cruise control switch located on the steering wheel to ensure it is operational. If the switch is functioning, turn your attention to the brake pedal switch, as this component must be working correctly for the cruise control to engage; a stuck or faulty switch will prevent activation. Following this, check the vehicle speed sensor, which is essential for the cruise control system to maintain speed; if this sensor is malfunctioning, it can lead to issues. Lastly, inspect the system for any vacuum leaks, as these can significantly hinder the performance of the cruise control. By systematically addressing these areas, you can effectively diagnose and potentially resolve the issues affecting your cruise control system.

What are the common problems that could cause the cruise control to stop working in a 1996 Mitsubishi Galant?

When dealing with a malfunctioning cruise control system in a 1996 Mitsubishi Galant, it's crucial to understand the common problems that may be at play. One of the first things to check is the fuse; a blown fuse can easily disrupt the entire system, rendering it inoperable. Additionally, the brake pedal switch is another critical component; if this switch is faulty, it may prevent the cruise control from engaging, as it is designed to deactivate when the brake is pressed. Speed sensor issues can also arise, leading to inaccurate speed readings that hinder the cruise control's ability to maintain a set speed. Furthermore, vacuum leaks can significantly impact the system's functionality, as they affect the engine's capacity to sustain a steady speed. Lastly, a malfunctioning cruise control module could be the root of the problem, as it is responsible for the overall operation of the system. By systematically diagnosing these potential issues, DIYers can effectively troubleshoot and restore the cruise control functionality in their Mitsubishi Galant.

How urgent is it to address the malfunctioning cruise control in my 1996 Mitsubishi Galant?

Addressing the malfunctioning cruise control in your 1996 Mitsubishi Galant is crucial for several reasons. First and foremost, a faulty cruise control system can lead to unexpected acceleration or deceleration, creating a hazardous driving environment that increases the risk of accidents. Additionally, when cruise control fails, drivers must manually maintain speed, which can be distracting and divert attention from the road, further heightening the danger. Ignoring these symptoms not only compromises safety but can also lead to more extensive wear and tear on your vehicle, resulting in potentially costly repairs down the line. Furthermore, a malfunctioning system can negatively affect your car's fuel efficiency, leading to unnecessary fuel consumption and increased expenses. Therefore, it is essential to prioritize the repair of your cruise control system to ensure a safe, efficient, and worry-free driving experience.
