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.
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 considering the urgency of repairing the non-functioning cruise control on a 2003 Ford F-350 Super Duty, it's essential to weigh the implications of neglecting this feature. While cruise control is primarily a convenience that enhances long-distance driving comfort, its malfunction can indicate underlying issues that may require attention. For instance, if the problem stems from a blown fuse or a faulty brake switch, these are relatively simple fixes that can prevent further complications. However, if the cruise control failure is linked to more complex systems, such as the control module or sensors, it could lead to more significant problems down the line. Although the immediate safety risk is low, addressing the issue promptly can improve your overall driving experience and prevent potential inconveniences during long trips. Therefore, while it may not be urgent, taking the time to diagnose and repair the cruise control system can enhance your vehicle's functionality and your comfort on the road.
