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.
To effectively diagnose the non-functioning cruise control in a 1999 Ford Taurus, start with the simplest checks before moving on to more complex diagnostics. Begin by inspecting the fuses related to the cruise control system, as a blown fuse can easily disrupt its operation. Next, assess the brake pedal and throttle body for any mechanical issues, since these components are integral to the cruise control's functionality. Utilizing a scanner can help identify any electronic or sensor-related problems that may be contributing to the malfunction. Pay special attention to the master cylinder's brake deactivation switch, as it is crucial for disengaging the cruise control when the brake is applied. Additionally, ensure that the cruise switch on the brake pedal is in good working order. Finally, start the vehicle and check the vacuum lines connected to the intake and brake booster for any leaks, as these can significantly impact the cruise control system's performance. By following this structured approach, you can systematically identify and resolve the issues affecting your cruise control.
When diagnosing cruise control issues in a 1999 Ford Taurus, it's essential to consider several common problems that may be at play. A failed control module can prevent the system from receiving the necessary signals to engage, while a blown fuse can cut off power entirely. Additionally, a defective brake pedal switch may inadvertently signal that the brakes are engaged, disabling the cruise control. Problems with the brake pedal position sensor or the throttle body can also disrupt the system's functionality, as they are critical for maintaining the desired speed. Furthermore, issues with the PRNDL or shifter position switch can lead to miscommunication between the transmission and the cruise control system. Lastly, a vacuum leak in the intake or brake booster can affect the system's performance, as it relies on proper vacuum levels to operate effectively. By systematically checking these components, DIY enthusiasts can identify and resolve the underlying issues affecting their cruise control system.
When it comes to the non-functioning cruise control in a 1999 Ford Taurus, understanding the urgency of the situation is crucial for both safety and convenience. If you frequently rely on cruise control for long drives, the inconvenience of a malfunction can be significant, making it a priority to address. Common issues such as blown fuses, faulty brake lights, or a malfunctioning brake switch are often straightforward to fix and can restore functionality quickly. However, if the problem stems from more complex engine-related issues, it becomes imperative to act swiftly to avoid potential safety hazards or further damage to your vehicle. Ignoring these symptoms can lead to more severe complications down the line, affecting not only your driving experience but also the overall safety of your vehicle. Regular maintenance and prompt attention to such issues are essential to ensure a smooth and safe driving experience, making it advisable not to overlook the importance of a functioning cruise control system.
