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 Explorer, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the fuse associated with the cruise control system, as a blown fuse can easily disrupt functionality. Next, assess the cruise control switch to ensure it is operational; a faulty switch can prevent the system from engaging. Following this, examine the brake pedal switch, which is crucial for disengaging the cruise control when brakes are applied; if this switch is malfunctioning, it can lead to issues. The vehicle speed sensor is another critical component to check, as it provides necessary data for the cruise control to function properly. Additionally, inspect for any vacuum leaks, as older models like the Explorer often rely on vacuum pressure for cruise control operation. If these steps do not resolve the issue, it may be time to consult a qualified mechanic for a more thorough diagnosis. By following this structured diagnostic approach, you can effectively troubleshoot the cruise control system in your vehicle.
When dealing with a malfunctioning cruise control system in a 1997 Ford Explorer, it's essential to understand the common problems that may be at play. One frequent issue is throttle failures, which can disrupt the communication between the accelerator and the cruise control system, preventing it from maintaining speed. Additionally, the cruise control module itself may experience malfunctions, leading to a complete failure of the system. Another critical component to check is the clock spring, as a broken clock spring can sever the connection necessary for the cruise control to function properly. By diagnosing these areas, DIYers can effectively identify the root cause of the problem and take the necessary steps to restore the cruise control functionality in their vehicle.
Addressing the non-functioning cruise control in a 1997 Ford Explorer should be considered a priority, as neglecting this issue can lead to significant safety risks and further complications. While it may not seem like an immediate emergency, the cruise control system is intricately linked to other critical vehicle functions, including the electrical system and components such as the brake light and steering controls. If these systems are compromised, it could result in more severe malfunctions that not only affect driving comfort but also pose a danger on the road. For instance, if the cruise control failure is associated with the ABS system, it could lead to reduced braking efficiency, increasing the risk of accidents. Therefore, it is advisable to have the cruise control issue diagnosed and repaired promptly to ensure the vehicle operates safely and efficiently, ultimately protecting both the driver and passengers.
