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.
To effectively diagnose a cruise control issue in your 1998 Acura RL, start by checking the signals into the cruise control module. This initial step is crucial as it helps confirm whether the system is receiving the correct input from the vehicle's controls. If the signals are intact, the next step is to inspect the actuator, which is responsible for controlling the throttle. A malfunctioning actuator can prevent the cruise control from engaging properly. If both the signals and actuator appear to be functioning, consider the possibility of a failed control module, which may require replacement. While these steps can guide you through the diagnostic process, consulting a professional mechanic is advisable for a thorough assessment, ensuring that any underlying issues are accurately identified and addressed.
When dealing with a malfunctioning cruise control system in a 1998 Acura RL, it's essential to consider several common problems that could be at play. One of the first areas to check is the cruise control switch, as a faulty switch can prevent the system from engaging. Additionally, a blown fuse within the cruise control circuit can lead to complete system failure, so inspecting the fuses is a crucial step. Another potential issue is vacuum leaks, which can disrupt the necessary pressure for the cruise control to function correctly. The speed sensor also plays a vital role; if it's defective, it may cause the cruise control to malfunction or disengage unexpectedly. Furthermore, the brake light switch is integral to the system's operation, and any issues here can prevent activation. Lastly, a malfunctioning throttle cable can hinder the cruise control's ability to maintain speed effectively. By systematically checking these components, DIYers can identify and address the root cause of cruise control issues in their Acura RL.
While the non-functioning cruise control in a 1998 Acura RL may not pose an immediate safety risk, it is still important to consider the implications of neglecting this repair. Cruise control enhances the driving experience, particularly on long trips, by allowing for a more relaxed driving style and potentially improving fuel efficiency. Ignoring the issue could lead to further complications, such as electrical problems or a malfunctioning throttle system, which might affect other vehicle functions. Therefore, while it may not be urgent, addressing the cruise control issue in a timely manner is advisable to ensure that your vehicle remains comfortable and fully functional. Taking the time to diagnose and repair this feature can prevent minor inconveniences from escalating into more significant problems down the road.

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.
If the cruise control refuses to turn on at all, the actuator could be at fault. Likewise, if the cruise control stays on but does not maintain a consistent speed, the problem could be a bad actuator. In extreme cases, a malfunctioning actuator could cause the throttle to stick and prevent the vehicle from slowing down. These symptoms may point to a bad actuator. They may also point to other problems with the cruise control and related systems.
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.
