The most common reasons a 1996 Kia Sportage 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 Kia Sportage 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 steps to diagnose the cruise control issue in a 1996 Kia Sportage?

To effectively diagnose a cruise control issue in a 1996 Kia Sportage, start with a systematic diagnostic approach that prioritizes simpler checks before moving on to more complex components. Begin by inspecting the brake light switch, as it plays a critical role in disengaging the cruise control when the brake pedal is pressed. Ensure that the brake lights are functioning properly, as a malfunctioning switch can prevent the cruise control from engaging. Next, test the cruise control switches located on the steering wheel; using a multimeter, check for continuity and voltage when each button is pressed to confirm they are operational. Following this, examine all electrical connections related to the cruise control system for any signs of corrosion or loose wires, as these can lead to intermittent issues. If your vehicle allows, perform a self-diagnostic test to check for error codes, which can provide insight into potential faults. Additionally, verify the functionality of the speed sensors and the ABS system, as these components are integral to the cruise control's operation. Finally, if the vehicle uses a mechanical actuator, test it by checking for proper voltage and continuity at the actuator's electrical connector. For detailed procedures tailored to your specific model, consulting the factory repair manual is highly recommended. By following this structured approach, you can effectively identify and address the underlying issues affecting the cruise control system in your Kia Sportage.

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

When troubleshooting cruise control issues in a 1996 Kia Sportage, it's essential to understand the common problems that may arise. One of the primary culprits is a faulty brake light switch, which plays a crucial role in signaling the cruise control system to deactivate when the brake pedal is pressed. If this switch malfunctions, it can prevent the cruise control from engaging properly. Additionally, faulty speed sensors, particularly those linked to the ABS system, can disrupt the cruise control's functionality, as the system relies on accurate speed readings to maintain the desired speed. Another potential issue is a damaged throttle actuator or cable, which is vital for adjusting the throttle in response to cruise control commands. Problems with the control module, responsible for managing various electronic systems, can also lead to cruise control malfunctions by failing to send the correct signals. Furthermore, a blown fuse related to the cruise control system, although less common, can be a simple fix that is often overlooked. Lastly, wear and tear on the steering wheel buttons or switches that control the cruise control can hinder its operation. By systematically checking these components, DIY enthusiasts can effectively diagnose and address the underlying issues affecting the cruise control system in their Kia Sportage.

How urgent is it to address the non-functioning cruise control in a 1996 Kia Sportage?

While the non-functioning cruise control in a 1996 Kia Sportage may not seem urgent from a safety perspective, it is crucial to recognize the potential consequences of ignoring this issue. The cruise control system, while primarily a convenience feature, can be indicative of underlying problems that may affect the vehicle's overall safety and functionality. For instance, a malfunctioning brake light switch could prevent the cruise control from disengaging when the brakes are applied, leading to dangerous driving conditions. Additionally, intermittent issues with the cruise control could signal deeper electrical or mechanical faults, such as problems with the Electronic Control Module (ECM) or steering wheel switches. These issues, if left unaddressed, could escalate and compromise other critical systems like ABS or traction control, ultimately resulting in more significant repairs and safety risks. Therefore, while the immediate urgency may be low, it is advisable to diagnose and resolve the cruise control issue promptly to maintain the vehicle's reliability and safety.
