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.
When troubleshooting cruise control issues in a Dodge Durango, it's essential to adopt a systematic diagnostic approach. Begin by checking the simplest components, such as the fuses related to the cruise control system, as a blown fuse can often be the root of the problem. Next, inspect the brake pedal switch, which can malfunction and inadvertently disable the cruise control. If these initial checks do not resolve the issue, turn your attention to the throttle control system and the ABS, as problems in these areas can significantly impact cruise control functionality. Additionally, examine the vacuum control piece under the hood, especially in older models where a broken vacuum line may be the culprit. If the cruise control operates intermittently, this may indicate loose connections or components that require tightening or replacement. By following this structured approach, you can efficiently diagnose and address the issues affecting your Dodge Durango's cruise control, restoring its functionality and enhancing your driving experience.
When diagnosing cruise control malfunctions in a Dodge Durango, it's essential to consider several common problems that could be at play. One frequent issue is related to the vacuum lines or the cruise control module, which can become damaged or disconnected, leading to a failure in the system's operation. Additionally, the control module itself, along with various sensors and switches, may fail, causing the cruise control to stop functioning correctly. A faulty throttle position sensor is another critical component that can disrupt the system, as it may cause the engine's computer to miscalculate fuel delivery, potentially resulting in black exhaust emissions. Furthermore, the brake-light switch and ABS sensor can also impact cruise control functionality, as they play a role in the system's overall operation. Lastly, if the SET, RESUME, CANCEL, or COAST buttons are malfunctioning, this could indicate deeper issues within the cruise control system. By understanding these common problems, DIY enthusiasts can better diagnose and address the issues affecting their Dodge Durango's cruise control.
When the cruise control in your Dodge Durango fails to operate, it’s crucial to understand the potential causes and the urgency of addressing them. A malfunctioning cruise control system can stem from several issues, including a faulty control module, sensor, or switch, which are essential for the system's operation. Additionally, problems with throttle actuation or vacuum lines can disrupt functionality, while a blown fuse or a defective brake pedal switch may also be to blame. Ignoring these symptoms can lead to more significant safety risks, as the cruise control system is designed to enhance driving convenience and stability. If the brake lights are malfunctioning, this can inadvertently cancel the cruise control, further complicating the issue. For those with Adaptive Cruise Control, it’s advisable to switch to regular cruise control to isolate the problem, as issues with adaptive sensors can also arise. Given the complexity of the cruise control system, diagnosing the exact cause may require specialized tools and expertise. Therefore, addressing these issues promptly is essential not only for restoring functionality but also for ensuring your safety on the road.
