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 the non-functioning cruise control in a 1998 Ford Explorer, it's important to adopt a systematic diagnostic approach. Begin by checking the fuse associated with the cruise control system, as a blown fuse is a common and easily fixable issue that can disrupt functionality. Next, inspect the cruise control switch to ensure it is operational; a malfunctioning switch can prevent the system from engaging. Additionally, examine the brake lights, as a faulty brake light switch can inadvertently disable the cruise control. It's also crucial to verify the vehicle speed sensor, which plays a vital role in the cruise control's operation by providing necessary speed data. Finally, consider using a diagnostic scanner to check for any error codes that may indicate specific problems within the cruise control system. By following these steps in order, you can effectively diagnose and potentially resolve the issues affecting your cruise control, making your DIY troubleshooting process more efficient.
When dealing with a non-functional cruise control system in a 1998 Ford Explorer, it's essential to consider several common issues that could 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 operation. Additionally, the brake pedal switch is crucial, as it disengages the cruise control when the brake is applied; if this switch is faulty, it may prevent the system from engaging altogether. Another potential culprit is the speed sensor, which is responsible for relaying the vehicle's speed to the cruise control system; any malfunction here can hinder the system's ability to maintain speed. Furthermore, vacuum leaks can significantly impact the functionality of the cruise control, as they can disrupt the necessary pressure for operation. It's also worth examining the cruise control module itself, as a malfunctioning module can lead to complete system failure. Lastly, wiring issues, such as frayed or disconnected wires, can prevent the cruise control from functioning properly. By systematically checking these components, DIYers can effectively diagnose and resolve the cruise control issues in their Ford Explorer.
Addressing the non-functioning cruise control in a 1998 Ford Explorer should be considered a priority for any DIY enthusiast. While it may not seem like an immediate emergency, neglecting this issue can lead to several complications that affect both safety and vehicle performance. A malfunctioning cruise control system can make long drives tedious, forcing the driver to constantly monitor and adjust speed manually, which can lead to fatigue. Moreover, the underlying causes of the cruise control failure, such as a blown fuse, faulty brake light, or malfunctioning brake switch, could indicate more serious problems that may compromise the vehicle's overall safety. Ignoring these symptoms not only risks increased fuel consumption during highway travel but could also lead to more significant repairs down the line. Additionally, if the cruise control issue is linked to a recall part that hasn't been addressed, it becomes even more critical to resolve the problem promptly. Therefore, while it may not be an urgent crisis, taking the time to diagnose and fix the cruise control system is essential for ensuring a safe and comfortable driving experience.
