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 Ford Explorer, it's essential to adopt a methodical diagnostic approach. Start by checking the simplest components, such as the brake pedal position switch and the cruise control fuse, as these are common culprits for malfunction. If these elements are functioning correctly, inspect the control switches and the speed control deactivation switch, as faults here can disrupt the cruise control system. Next, consider the brake pressure deactivator switch, which is often a significant factor in cruise control failures. If the problem persists, investigate the throttle control system and the ABS system, as issues in these areas can also affect cruise control functionality. Lastly, if all else fails, examine the master cylinder brake fluid pressure sensor, as a faulty sensor may require replacement to restore proper operation. By following this structured approach, you can efficiently identify and resolve the underlying issues affecting your Ford Explorer's cruise control system.
When dealing with cruise control malfunctions in a Ford Explorer, it's crucial to understand the various common problems that could be at play. A failed control module is often the primary culprit, as it manages the cruise control system's operations. Additionally, issues with the cruise control switch itself can prevent the system from engaging, leading to frustration for drivers. Another frequent issue arises from a defective brake pedal position switch, which can inadvertently signal that the brakes are engaged, thus disabling cruise control. It's also important to check for a blown fuse, as this can disrupt power to essential components, including the cruise control switch and the vehicle's Speed Sensor (VSS). Furthermore, problems within the throttle control system can hinder the cruise control's functionality, while issues with the Anti-lock Braking System (ABS) may also contribute to the malfunction. By systematically examining these potential failure points, DIYers can effectively diagnose and address the root cause of their cruise control issues, restoring this convenient feature to their Ford Explorer.
When the cruise control in your Ford Explorer fails to operate, it’s crucial to address the issue promptly, as neglecting it can lead to safety risks and further complications. Common reasons for malfunction include a failed control module, defective sensors, or issues with the brake pedal position switch. These components are essential for the proper functioning of the cruise control system, and if they are not working correctly, it can lead to unexpected acceleration or inability to maintain speed, which poses a significant safety hazard. Additionally, a blown fuse or faulty control switches can disrupt the system, while older models may experience problems due to broken vacuum lines. It’s also important to consider the throttle control system and ABS, as issues here can further complicate the situation. If you suspect a faulty brake pressure switch, it’s imperative to address it immediately, as it can lead to dangerous conditions, including fire hazards. By diagnosing and resolving these issues quickly, you can ensure your Ford Explorer remains safe and reliable on the road.
