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 diagnosing the non-functioning cruise control in a 1999 Ford Explorer, it's essential to adopt a methodical diagnostic approach. Begin by checking the fuse associated with the cruise control system, as a blown fuse is a straightforward issue that can easily disrupt functionality. Next, inspect the wiring for any visible damage or loose connections, as faulty wiring can significantly hinder the system's performance. After ensuring the electrical components are intact, test the cruise control buttons on the steering wheel to confirm they are responsive; unresponsive buttons may indicate a malfunctioning control switch. Utilizing an OBD-II scanner to check for error codes can provide valuable insights into specific issues affecting the cruise control system. Lastly, since older vehicles often rely on vacuum lines, inspect these for any leaks or damage that could impair operation. By following this structured approach, you can effectively diagnose and address the issues with your cruise control system, ensuring a smoother driving experience.
When troubleshooting cruise control issues in a 1999 Ford Explorer, it's essential to consider several common problems that could be affecting its functionality. One of the primary culprits is a failed control module, which is responsible for processing signals from various components. If this module is malfunctioning, it may prevent the cruise control from engaging. Additionally, sensor or switch issues can arise, particularly with the brake pedal switch or the speed sensor, both of which play critical roles in the cruise control system. If these sensors fail to send the correct signals, the cruise control may not activate or could disengage unexpectedly. Lastly, throttle actuation problems can also hinder cruise control performance; if the throttle body is dirty or the throttle cable is damaged, it may not respond correctly to the cruise control commands. By systematically checking these components, DIYers can effectively diagnose and potentially resolve the cruise control issues in their Ford Explorer.
When it comes to a non-functioning cruise control in a 1999 Ford Explorer, the urgency of addressing the issue cannot be overstated. While it may not seem like an immediate emergency, neglecting this problem can lead to significant safety risks and potential damage to your vehicle. A malfunctioning cruise control system often points to underlying issues within the vehicle's electrical system or sensors, which, if left unchecked, could escalate into more serious problems. Moreover, the convenience of cruise control is particularly valuable during long drives, as it helps maintain a steady speed, reduces driver fatigue, and can even enhance fuel efficiency. Therefore, it is crucial to inspect and repair the cruise control system promptly. For DIY enthusiasts, this means taking the time to diagnose the issue, whether it involves checking fuses, inspecting wiring, or testing the throttle position sensor. By addressing the malfunction early, you not only ensure your safety on the road but also maintain the overall performance of your Ford Explorer.
