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.
While repairing the non-functioning cruise control in a 1990 Jaguar Vanden Plas may not seem urgent, it is important to recognize the benefits of addressing the issue sooner rather than later. A functional cruise control system not only enhances driving comfort by reducing fatigue on long journeys but can also contribute to better fuel efficiency. Ignoring the problem could lead to further complications, such as increased wear on other vehicle components or the development of more serious electrical issues. Common culprits for cruise control failure include a blown fuse, faulty brake switch, or wiring problems, which, if left unchecked, might escalate into more significant repairs. Therefore, while it may not be critical for immediate vehicle performance, timely diagnosis and repair can prevent future inconveniences and ensure a more enjoyable driving experience.
