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 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.
Addressing the non-functioning cruise control in your 2007 Volvo S80 should not be overlooked, as it can significantly impact both your driving experience and safety on the road. While it may seem like a minor inconvenience, a malfunctioning cruise control system can lead to fatigue during long drives, increasing the risk of accidents. Moreover, the underlying issues causing the malfunction—such as faulty fuses, switches, or sensors—could potentially escalate into more serious problems if left unaddressed. Timely repairs not only restore the comfort of maintaining a steady speed but also ensure that your vehicle operates safely, particularly on highways where cruise control is most beneficial. Therefore, it is advisable to prioritize the diagnosis and repair of your cruise control system to enhance your driving safety and overall vehicle performance.
