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.
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.
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.
To effectively diagnose cruise control issues in a 1999 Suzuki Vitara, begin with a thorough inspection of the vehicle's fuse box. Start by checking the cruise control fuse, as a blown fuse is often the simplest and most common cause of malfunction. Next, ensure that the brake lights are functioning properly, as any failure in the brake light circuit can directly impact the cruise control system. Pay particular attention to the brake light switch; if the switch does not close when the brake pedal is released, it will prevent the cruise control from engaging. If your Vitara is equipped with a manual transmission, also verify the condition of the clutch switch contacts, as these must be detected by the ECU to activate cruise control. Finally, check for any additional fuses related to the cruise control system, as disruptions in power supply to components like the cruise control switch or speed sensor can also lead to issues. By following these steps, you can systematically identify and address the root cause of cruise control problems in your vehicle.
When dealing with cruise control failure in a 1999 Suzuki Vitara, it's essential to understand the common problems that may be at play. One of the primary culprits is often a failed control module, which can disrupt the entire cruise control system. Additionally, sensor or switch issues, particularly with the throttle position sensor, can lead to malfunctions, preventing the cruise control from engaging properly. It's also worth checking for a blown fuse, as this can easily interrupt the electrical flow necessary for the system to function. Another frequent issue is a defective brake pedal switch; if this switch is malfunctioning, it may incorrectly signal that the brakes are engaged, thereby disabling the cruise control. Furthermore, problems with the throttle control system, including vacuum line leaks in older models, can significantly impact performance. Lastly, issues related to the ABS system may also contribute to cruise control failures. By systematically examining these components, DIYers can effectively diagnose and potentially resolve the cruise control issues in their Suzuki Vitara.
When assessing the urgency of repairing the non-functioning cruise control in your 1999 Suzuki Vitara, it's crucial to weigh several factors that can influence your decision. Although cruise control is primarily a convenience feature, its malfunction can lead to increased driver fatigue during long journeys, potentially compromising safety. If you find that the lack of cruise control significantly detracts from your driving comfort or poses a distraction, prioritizing the repair becomes more critical. Additionally, conducting a diagnostic assessment can reveal the underlying cause of the issue, helping you understand whether it’s a simple fix or something more complex that could escalate if left unaddressed. The cost of repair is another important consideration; if the repair is manageable within your budget, addressing it sooner can prevent further complications down the line. Lastly, neglecting the cruise control issue may not immediately affect your vehicle's performance, but unresolved problems can lead to additional repairs in the future. By evaluating these factors, you can make a more informed decision about the urgency of the repair, ensuring both your safety and the longevity of your vehicle.
