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.
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 diagnose the non-functioning cruise control on a 1998 Dodge Durango, begin with the simplest checks to avoid unnecessary complications. Start by inspecting the fuse associated with the cruise control system, as a blown fuse is a common and easily fixable issue. Next, examine the cruise control buttons on the steering wheel; if they are not responding, they may need repair or replacement. Following this, check the vacuum lines, which are crucial for the operation of the cruise control in older vehicles. Look for any signs of leaks or damage that could disrupt the system's functionality. Additionally, test the brake pedal switch, as this component is designed to disengage the cruise control when the brake is applied; a malfunction here can lead to unexpected deactivation. Finally, ensure that the speed sensor is working correctly, as it plays a vital role in maintaining a consistent speed. By systematically addressing these areas, you can effectively diagnose and potentially resolve the cruise control issues in your Dodge Durango.
When troubleshooting cruise control issues in a 1998 Dodge Durango, it's essential to consider several common problems that could be at play. A primary culprit is often a failed control module, which can disrupt the entire cruise control system's functionality. Additionally, sensor or switch malfunctions can prevent the system from engaging or maintaining speed, as these components are crucial for proper operation. Another frequent issue involves throttle actuation; if the throttle isn't responding correctly, it can lead to cruise control failure. It's also vital to check the brake lights, as non-functioning lights can send incorrect signals to the cruise control system, causing it to disengage unexpectedly. For those attempting a DIY fix, be aware that accessing the cruise control system may require specialized tools like a DRBIII, as standard OBDII scanners won't suffice. If your Durango features Adaptive Cruise Control, toggling it off and reverting to the standard cruise control can help isolate the problem. By systematically addressing these potential issues, you can effectively diagnose and potentially resolve the cruise control malfunction in your vehicle.
When considering whether to address the non-functioning cruise control in your 1998 Dodge Durango, it's essential to weigh the potential consequences of neglecting this issue. While some drivers may find cruise control less critical, especially in urban settings, the feature plays a significant role in enhancing driving comfort and safety during long trips. A malfunctioning cruise control system can lead to unexpected acceleration or difficulty in decelerating, particularly if it fails to disengage when the brake pedal is pressed. This not only compromises your driving experience but also poses a serious safety risk to you and others on the road. Furthermore, underlying issues such as faulty wiring or a defective throttle actuator could affect your vehicle's overall performance, leading to more extensive and costly repairs down the line. Therefore, regardless of your driving habits, it is advisable to address the cruise control malfunction promptly to ensure both your safety and the optimal functioning of your vehicle.
