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.
To effectively diagnose the non-functioning cruise control in a 1997 Ford Contour, it's essential to adopt a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Begin by inspecting the fuse associated with the cruise control system, as a blown fuse is a common and easily rectifiable issue. Next, assess the functionality of the cruise control buttons on the steering wheel; faulty buttons can hinder engagement. Following this, examine the brake pedal switch, which is crucial since the cruise control disengages when the brake is applied. It's also important to check for any vacuum leaks in the lines connected to the cruise control module, as these can disrupt the system's operation. Additionally, verify the speed sensor's performance, as a malfunction here can prevent the cruise control from maintaining speed. Finally, utilizing an OBD-II scanner to check for error codes can provide valuable insights into any underlying issues. By following this structured diagnostic approach, you can efficiently identify and resolve the problem with your cruise control system.
When troubleshooting the cruise control system in a 1997 Ford Contour, it's essential to understand the common problems that may lead to its failure. One of the primary culprits is a faulty brake pedal switch, which is designed to disengage the cruise control when the brake is applied; if this switch malfunctions, it can prevent the system from engaging. Another frequent issue is a defective speed sensor, which is crucial for maintaining a constant speed; without accurate readings, the cruise control may not function properly. Additionally, vacuum leaks can significantly impact the system's performance, as they can lead to a loss of vacuum pressure necessary for operation. It's also important to consider the cruise control module itself, as any defects here can hinder the system's overall functionality. Lastly, a blown fuse in the cruise control circuit can easily disrupt the system, so checking and replacing any faulty fuses is a straightforward step in the troubleshooting process. By systematically addressing these potential issues, DIY enthusiasts can effectively diagnose and resolve cruise control problems in their Ford Contour.
Addressing the non-functioning cruise control in a 1997 Ford Contour is important for several reasons. First and foremost, safety should be a priority; a malfunctioning cruise control system can lead to unpredictable vehicle behavior, such as sudden acceleration or deceleration, which can be particularly dangerous on highways. Additionally, the absence of this feature can significantly reduce driver comfort during long trips, as cruise control is designed to alleviate fatigue by maintaining a steady speed. Furthermore, neglecting this issue could result in more severe damage to the vehicle's systems over time, leading to costly repairs. Therefore, while it may not seem like an immediate emergency, it is wise to have the cruise control system inspected by a qualified mechanic as soon as possible to ensure a safe and comfortable driving experience.
