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.
A faulty cruise control module will simply result in deactivation of cruise control settings. This is because a detected error in the cruise control system could lead to hazardous driving conditions, so the module will be disabled, and the cruise control system warning light will be displayed. This will be a different message depending on make and model, and a warning light or message may be displayed on the driver instrument cluster.
To effectively diagnose the non-functioning cruise control on your 1997 Plymouth Grand Voyager, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the fuse associated with the cruise control system, as a blown fuse is a common and easily fixable issue. Next, examine the cruise control switch to ensure it is operational; a malfunctioning switch can prevent the system from engaging. Following this, check the brake pedal switch, which is critical for cruise control functionality; if this switch is stuck or faulty, it will disable the system. After these initial checks, test the speed sensor, as it provides essential data for the cruise control to function correctly. Additionally, inspect for any vacuum leaks in the lines and connections, as these can significantly affect performance. Finally, if the problem persists, utilize a diagnostic scanner to identify any error codes that may indicate specific issues within the cruise control system. By following this structured diagnostic approach, you can efficiently identify and address the root cause of the cruise control malfunction.
When troubleshooting the cruise control system in a 1997 Plymouth Grand Voyager, it's essential to consider several common problems that could be at play. One of the first things to check is the vehicle's fuse box, as a blown fuse can easily disrupt the cruise control functionality. Additionally, the brake pedal switch is a critical component; if it is faulty, it may prevent the cruise control from engaging, as the system is designed to deactivate when the brake is applied. Another potential issue could be vacuum leaks within the system, which can lead to improper operation of the cruise control. Furthermore, a defective speed sensor can cause inaccurate speed readings, ultimately affecting the cruise control's ability to maintain the desired speed. Lastly, don't overlook the condition of the cruise control buttons themselves, as wear and tear over time can hinder their performance. By systematically checking these areas, you can effectively diagnose and address the issues causing the cruise control to malfunction in your vehicle.
When contemplating the urgency of repairing the non-functioning cruise control in your 1997 Plymouth Grand Voyager, it's essential to weigh the implications of neglecting this feature. While cruise control is primarily a convenience, its absence can lead to increased driver fatigue, especially on long journeys, which may inadvertently compromise safety. Additionally, if you plan to sell your vehicle, having all features operational, including cruise control, can enhance its appeal and potentially increase its resale value. Before making a decision, consider having a mechanic conduct a diagnostic check to identify the underlying issue. This proactive step not only clarifies the extent of the problem but also helps you assess whether it poses any safety risks or could lead to further complications down the line. Ultimately, while the repair may not be immediately urgent, addressing it sooner rather than later can contribute to a more comfortable driving experience and preserve the vehicle's value.
