The most common reasons a Plymouth Prowler cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.
  • Sensor: A faulty or malfunctioning sensor can lead to incorrect readings, causing issues with engine performance or other systems relying on accurate data.
  • Control Module: A faulty control module can lead to erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
  • Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent throttle response.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a Plymouth Prowler cruise control isn't working?

Common Repairs

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.

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.

Troubleshooting Cruise Control Issues in a Plymouth Prowler

When troubleshooting cruise control issues in a Plymouth Prowler, it's essential to adopt a systematic diagnostic approach that begins with the simplest solutions before progressing to more complex assessments. Start by checking the fuses related to the cruise control system, as a blown fuse can often be the root of the problem. Next, inspect the brake pedal and throttle body for any signs of wear or malfunction, as these components directly influence cruise control functionality. If these initial checks do not resolve the issue, using a diagnostic scanner can help identify any error codes or sensor malfunctions, particularly focusing on the speed sensor's operation. Additionally, consider the condition of the control module and switches, as failures here can lead to significant cruise control malfunctions. Some users have found that simply stopping the vehicle and restarting it can temporarily restore cruise control functionality, so this quick fix is worth trying. Lastly, be mindful of any check engine lights or engine-related issues, as these can also impact the cruise control system. By following this structured approach, you can effectively diagnose and address the cruise control problems in your Plymouth Prowler.

What Are the Common Issues Causing Cruise Control Failure in a Plymouth Prowler?

When diagnosing cruise control failure in a Plymouth Prowler, it's crucial to understand the various common problems that could be affecting the system. One of the primary issues often encountered is a malfunctioning control module, which can disrupt the entire cruise control operation. Additionally, blown fuses are a frequent culprit, as they can interrupt the power supply necessary for the cruise control to function. Another area to investigate is the brake pedal position sensor; if this sensor is faulty, it may incorrectly signal that the brakes are engaged, thereby disabling the cruise control. Throttle body malfunctions can also play a significant role, as they affect the vehicle's ability to maintain speed. Furthermore, issues with the PRNDL or shifter position switch can lead to similar problems. In older models, a broken vacuum line may be the reason behind cruise control failure, while a defective brake pedal switch or problems with the ABS can also contribute to the malfunction. Lastly, any engine-related issues, including a check engine light or faulty brake lights, should not be overlooked, as they can prevent the cruise control from operating correctly. By systematically checking these components, DIY enthusiasts can effectively troubleshoot and potentially resolve cruise control issues in their Plymouth Prowler.

Why is the Cruise Control Not Working in a Plymouth Prowler?

When the cruise control in your Plymouth Prowler fails to operate, it is crucial to address the issue promptly, as neglecting it can lead to safety risks and further vehicle complications. Common causes include a malfunctioning control module, faulty sensors, or defective switches, which can disrupt the cruise control system's functionality. Additionally, a blown fuse or a defective brake pedal switch may prevent the system from engaging, while throttle actuation problems can hinder its performance. In older models, a broken vacuum line could also be the culprit. If you notice intermittent operation or the CRUISE light not illuminating, it is advisable to check the related fuse, as this is a frequent source of failure. Ignoring these symptoms not only compromises your driving experience but could also lead to more significant repairs down the line, making it essential to diagnose and resolve the issue as soon as possible.
