The most common reasons a 1992 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 1992 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.

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.

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 steps to diagnose the non-functioning cruise control in a 1992 Mitsubishi Galant?

To effectively diagnose the non-functioning cruise control in your 1992 Mitsubishi Galant, start with a systematic approach that prioritizes simpler checks before delving into more complex issues. Begin by inspecting the cruise control fuse; a blown fuse can often be the simplest explanation for a malfunction. Next, examine the cruise control switch located on the steering wheel to confirm it is operational. If these components are functioning correctly, turn your attention to the vacuum hoses associated with the cruise control system, as any leaks or damage here can disrupt performance. Additionally, ensure that the throttle cable is properly adjusted and securely connected, as misalignment can hinder the system's ability to maintain speed. Finally, check the brake pedal switch, since a stuck or faulty switch can inadvertently disable the cruise control. By following these steps, you can methodically identify and address the issues affecting your cruise control system, potentially saving time and money on repairs.

What are the common problems that could cause the cruise control to stop working in a 1992 Mitsubishi Galant?

When dealing with a malfunctioning cruise control system in a 1992 Mitsubishi Galant, it's essential to understand the common problems that may be at play. One of the first things to check is the fuse associated with the cruise control; a blown fuse can easily disrupt the system's functionality. If the fuse is intact, the next step is to inspect the cruise control switch, as a faulty switch can prevent the system from engaging or disengaging properly. Additionally, vacuum leaks are a frequent culprit, as they can interfere with the system's operation, leading to inconsistent performance. Another critical component to examine is the speed sensor; if it is malfunctioning, the cruise control may struggle to maintain a steady speed. Furthermore, issues with the brake light switch can also hinder the cruise control's ability to function correctly, as it relies on this switch to know when to disengage. Lastly, don't overlook the throttle cable, as any malfunction here can impact the system's ability to maintain speed effectively. By systematically checking these components, DIYers can often identify and resolve the issue, restoring the cruise control functionality in their Galant.

How urgent is it to address the malfunctioning cruise control in my 1992 Mitsubishi Galant?

Addressing the malfunctioning cruise control in your 1992 Mitsubishi Galant is crucial for both safety and vehicle performance. A faulty cruise control system can lead to unexpected acceleration or deceleration, significantly increasing the risk of accidents on the road. Ignoring these symptoms not only jeopardizes your safety but also that of other drivers. Furthermore, delaying repairs can exacerbate the problem, potentially causing more extensive damage to the vehicle's components, which could result in costly repairs down the line. By prioritizing the repair of your cruise control, you not only enhance your driving experience but also ensure that your vehicle operates efficiently and safely. Therefore, it is essential to take immediate action to resolve any issues with your cruise control system.
