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 faced with a non-functional cruise control in a 1999 Plymouth Prowler, it's crucial to adopt a systematic diagnostic approach. Begin by checking the fuse associated with the cruise control system, as a blown fuse can often be the simplest explanation for the malfunction. Next, inspect the cruise control switch for any visible damage or wear, as this component is vital for activating the system. Following this, examine the brake pedal switch, which is designed to disengage the cruise control when the brake is applied; if this switch is faulty, it may prevent the cruise control from functioning. Additionally, testing the vehicle speed sensor is essential, as it provides the necessary speed data to the cruise control module. Finally, utilizing a diagnostic scanner to check for error codes can reveal underlying issues that may not be immediately apparent. By methodically working through these steps, you can effectively diagnose and address the cruise control problem in your Plymouth Prowler.
When troubleshooting the cruise control system in a 1999 Plymouth Prowler, it's essential to consider several common problems that could be affecting its functionality. One of the first areas to check is the cruise control switch, as a faulty switch can prevent the system from engaging properly. Additionally, a blown fuse may disrupt the electrical flow necessary for the cruise control to operate, so inspecting the fuses is a crucial step. Another potential issue could be vacuum leaks within the system, which can lead to a loss of functionality and should be checked for any signs of wear or damage. The speed sensor also plays a vital role; if it is defective, the cruise control may struggle to maintain the desired speed. Furthermore, the brake light switch can interfere with the cruise control operation, as it is designed to disengage the system when the brakes are applied. Lastly, don’t overlook the throttle cable, as any malfunction here can hinder the cruise control's ability to maintain speed effectively. By systematically examining these components, you can accurately diagnose and address the cruise control issues in your Plymouth Prowler.
Repairing the non-functioning cruise control in a 1999 Plymouth Prowler should be prioritized due to its implications for safety, convenience, and resale value. While the immediate safety risk may not seem critical, a malfunctioning cruise control system can lead to erratic speed changes, increasing the likelihood of accidents, especially on highways where maintaining a steady speed is crucial. Additionally, without cruise control, drivers may experience increased fatigue during long trips, making the driving experience less enjoyable and more taxing. Furthermore, if you plan to sell your Prowler in the future, a non-operational cruise control could deter potential buyers and diminish the vehicle's resale value. Therefore, addressing this issue promptly not only enhances your driving experience but also safeguards your investment in the long run.

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.
