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 Escort, it's essential to adopt a methodical approach that begins with the most straightforward solutions. Start by checking the fuse associated with the cruise control system, as a blown fuse is a common and easily fixable issue that can halt 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 pedal switch, which is crucial since the cruise control disengages when the brake is applied. If these components are functioning correctly, turn your attention to the vacuum lines, as leaks can disrupt the system's operation. Finally, if the problem persists, using a diagnostic scanner to check for error codes can provide valuable insights into any underlying issues. By following this structured diagnostic approach, you can effectively identify and resolve the problems affecting your cruise control system.
When the cruise control in a 1999 Ford Escort ceases to function, several common problems may be at play. One of the first areas to investigate is the vacuum actuator, which is essential for the cruise control system's operation; if it fails, the system will not engage. Additionally, a blown fuse can disrupt power to the cruise control, so checking the fuses related to both the cruise control and brake lights is crucial. The brake switch also plays a significant role, as a faulty switch can prevent the cruise control from activating, especially if it mistakenly signals that the brakes are engaged. Lastly, any issues indicated by the check engine light or other engine-related problems can interfere with the cruise control's functionality. By systematically checking these components, you can effectively diagnose and potentially resolve the issue, making it a manageable DIY project.
Repairing the non-functioning cruise control in a 1999 Ford Escort should be approached with a sense of urgency, primarily due to the safety risks associated with a malfunctioning system. A faulty cruise control can lead to unexpected acceleration or deceleration, which can compromise your control over the vehicle, especially during long drives where fatigue is a concern. Additionally, restoring this feature not only enhances your driving comfort by reducing the physical strain of maintaining speed on highways but also contributes to a more enjoyable driving experience. Furthermore, keeping all vehicle systems, including cruise control, in good working order is essential for preserving the car's resale value. Potential buyers are more likely to be attracted to a well-maintained vehicle that demonstrates attention to detail in its upkeep. Therefore, while it may not seem like an immediate emergency, addressing the cruise control issue promptly is advisable to ensure safety, enhance comfort, and maintain the vehicle's overall value.
