The most common reasons a Dodge Monaco 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 Dodge Monaco 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.

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.

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 Dodge Monaco

When troubleshooting cruise control issues in a Dodge Monaco, it's essential to adopt a systematic diagnostic approach that begins with the simplest solutions before progressing to more complex assessments. Start by checking for any blown fuses related to the cruise control system, as this is a frequent culprit that can easily disrupt functionality. Next, inspect the brake pedal and throttle body for any signs of wear or malfunction, since these components play a critical role in the cruise control's operation. Utilizing a diagnostic scanner can help you identify any underlying issues, particularly with the speed sensor, which is vital for the system's performance. If problems persist, consider resetting the Steering Column Control Module fuse located under the passenger side dash, as this has been known to resolve certain cruise control malfunctions. Additionally, be aware that any active faults in the ABS brake system can disable cruise control, so addressing these issues is crucial for restoring full functionality. By following this structured approach, you can effectively diagnose and potentially resolve cruise control problems in your Dodge Monaco.

Troubleshooting Cruise Control Issues in a Dodge Monaco

When troubleshooting cruise control issues in a Dodge Monaco, it's essential to be aware of several common problems that can hinder its performance. One frequent culprit is a blown fuse, which can disrupt the entire cruise control system. Additionally, the condition of the brake pedal and throttle body plays a critical role; if either component is malfunctioning, it can prevent the cruise control from engaging properly. Another important aspect to consider is the speed sensor, as any faults here can lead to erratic behavior or complete failure of the cruise control system. Utilizing a diagnostic scanner can help pinpoint these issues effectively. Furthermore, resetting the Steering Column Control Module fuse may resolve some problems, as this has been a successful fix for many owners. Lastly, be mindful that active faults in the ABS system can also disable cruise control, so addressing any brake-related issues is crucial for restoring functionality. By understanding these common problems, you can take informed steps to troubleshoot and potentially fix the cruise control system in your Dodge Monaco.

Why is the Cruise Control Not Working in a Dodge Monaco?

When the cruise control in your Dodge Monaco fails to operate, it’s crucial to address the problem promptly, as neglecting it can lead to safety risks while driving. Common culprits include a blown fuse or a malfunctioning brake pedal switch, both of which are relatively easy to check and replace. Additionally, issues with the throttle control system or the anti-lock braking system (ABS) can disrupt cruise control functionality, making it essential to inspect these components as well. In older models, a broken vacuum line may be the root cause, so examining the vacuum system is advisable. Furthermore, software glitches affecting the necessary inputs and outputs can also disable the cruise control, highlighting the importance of using a diagnostic scanner to identify any underlying electronic issues. Engaging the engine brake inadvertently can also prevent cruise control from functioning, so ensure that this feature is not activated. By systematically troubleshooting these areas, you can effectively diagnose and resolve the cruise control issue, ensuring a safer driving experience and preventing potential damage to your vehicle.
