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.
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.
When troubleshooting the non-functioning cruise control in a 1991 Ford Explorer, it's crucial to follow a structured diagnostic approach that prioritizes simpler checks before delving into more complex issues. Begin by inspecting the fuse linked to the cruise control system, as a blown fuse can easily disrupt its operation. Next, examine the cruise control buttons on the steering wheel for any signs of damage or sticking, which could prevent the system from engaging. After that, verify the functionality of the speed sensor, as it plays a vital role in the cruise control's operation. In older vehicles like the Explorer, it's also important to check the vacuum lines for any leaks or damage, as these can significantly affect performance. Additionally, ensure that the brake pedal switch is working correctly, since it is designed to disengage the cruise control when the brake is applied. Finally, using a diagnostic scanner to check for error codes can provide valuable insights into any underlying issues. By systematically addressing these areas, you can effectively identify and resolve the problems affecting your cruise control system.
When the cruise control in a 1991 Ford Explorer ceases to function, it can be attributed to several common problems that are relatively straightforward to diagnose and repair. One of the primary culprits is a defective brake pedal position switch, which can prevent the cruise control from engaging properly. Additionally, a blown fuse may disrupt the electrical circuit necessary for the cruise control system to operate, making it a simple fix that involves checking and replacing the fuse if needed. Faulty control switches can also hinder functionality, as they are responsible for activating the cruise control system. Another potential issue is the brake pressure deactivator switch, which can inadvertently signal the system to disengage. Furthermore, a malfunctioning throttle can affect the cruise control's ability to maintain speed, while a faulty brake light or bad brake switch can create confusion in the system's operation. By systematically checking these components, DIYers can effectively troubleshoot and restore the cruise control functionality in their Ford Explorer.
Addressing a non-functioning cruise control in a 1991 Ford Explorer is more urgent than it may initially seem. While it might not appear to be an immediate emergency, the implications of ignoring this issue can be significant. A malfunctioning cruise control system can indicate deeper problems within the vehicle's electrical system or sensors, which, if left unchecked, could lead to more severe mechanical failures. Moreover, the absence of cruise control can increase driver fatigue during long trips, making it harder to maintain focus and control, especially on highways where consistent speed is crucial. This not only compromises your safety but also that of others on the road. By taking the time to inspect and repair the cruise control system promptly, you can prevent potential accidents and avoid costly repairs down the line. Therefore, for DIY enthusiasts, addressing this issue should be a priority to ensure a safe and efficient driving experience.
