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.
When considering the urgency of repairing the non-functioning cruise control in your 2000 Jaguar S-Type, it's essential to recognize that while it may seem like a minor inconvenience, neglecting this issue could lead to more significant problems down the line. Cruise control is not just a luxury; it plays a crucial role in maintaining a consistent speed, which can enhance fuel efficiency and reduce driver fatigue during long trips. If you frequently drive on highways, the absence of this feature can lead to discomfort and increased stress, potentially affecting your overall driving experience. Moreover, a malfunctioning cruise control system may indicate underlying electrical issues that could escalate if left unaddressed, leading to costly repairs or even safety risks. For instance, if the problem stems from a blown fuse, it might be a straightforward fix, but ignoring it could mask more severe electrical faults. Therefore, if you find yourself relying on cruise control for comfort and convenience, it is advisable to prioritize this repair to ensure your vehicle operates safely and efficiently.
