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 your Ford Explorer Sport, start by checking the simplest components first. Begin with the cruise control fuse; a blown fuse can easily disrupt the system, so inspect it and replace it if necessary. Next, examine the control switches for any signs of wear or malfunction, as faulty switches can prevent the cruise control from engaging. If these initial checks do not resolve the issue, move on to the cruise control cutout switch, which is designed to deactivate the system when the brakes are applied. Ensure that this switch is functioning correctly. If the problem persists, it may be time to investigate the control module and sensors, as failures in these components are common culprits for cruise control malfunctions. By following this diagnostic approach, you can systematically identify and address the root cause of the cruise control issues in your vehicle, potentially saving time and repair costs.
When dealing with cruise control malfunctions in a Ford Explorer Sport Trac, it's essential to recognize the various common problems that could be at fault. One of the primary culprits is a failed control module, which can disrupt the entire cruise control system. Additionally, sensor issues, particularly with the throttle position sensor, can lead to erratic behavior, such as the engine overcompensating with fuel, resulting in black exhaust. Another frequent issue arises from the brake pedal position switch; if this switch is defective, it may prevent the cruise control from engaging or cause it to disengage unexpectedly. Furthermore, problems with the speed control deactivation switch or the throttle control system can also contribute to the malfunction. Lastly, the anti-lock braking system (ABS) can interfere with cruise control functionality if it detects a fault. By understanding these potential issues, DIYers can better diagnose and address the specific problems affecting their vehicle's cruise control system, ensuring a safer and more efficient driving experience.
When the cruise control in your Ford Explorer Sport fails to operate, it’s crucial to address the issue promptly, as neglecting it could lead to safety risks or further vehicle damage. Common culprits include a malfunctioning control module, faulty sensors, or defective switches, all of which can disrupt the cruise control system's functionality. Additionally, problems with throttle actuation can prevent the system from engaging properly. A critical safety feature in many Ford vehicles is the brake light switch, which can disengage cruise control if it detects brake pedal depression; if this switch is malfunctioning, it may inadvertently cancel your cruise control settings. Other potential issues include a blown fuse, a defective brake pedal switch, or complications within the throttle control system. In older models, a broken vacuum line can also be a factor. Furthermore, if your check engine light is illuminated, it may indicate underlying engine problems that could affect cruise control performance. Therefore, it’s essential to troubleshoot these issues as soon as they arise to ensure your vehicle remains safe and reliable on the road.
