The most common reasons a Chevrolet Beretta 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 Chevrolet Beretta 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.

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.

Troubleshooting Cruise Control Issues in a Chevrolet Beretta

When troubleshooting cruise control issues in a Chevrolet Beretta, it's essential to adopt a systematic diagnostic approach. Begin by checking the control module, sensor, and throttle, as these components are often the root of the problem. Next, inspect the vacuum lines for any signs of wear or leaks, as these can significantly impact the system's performance. Don't forget to verify the cruise control fuse; a blown fuse can interrupt power to critical components, so replacing it may resolve the issue. If these initial checks do not yield results, conduct a cruise switch short test to identify any shorts in the wiring connected to the Cruise Control Module. Should the wiring appear intact, examine the Multi-Function Lever and Cruise Control Switches for potential faults. Additionally, be mindful of sensor failures and throttle problems, as these can also hinder cruise control functionality. Addressing these issues promptly is crucial, not only for restoring your cruise control system but also for ensuring safe vehicle operation. By following this structured approach, you can effectively diagnose and resolve cruise control issues in your Chevrolet Beretta.

Troubleshooting Cruise Control Issues in a Chevrolet Beretta

When troubleshooting cruise control issues in a Chevrolet Beretta, it's essential to understand the common problems that can arise within the system. One frequent issue is a blown fuse, which can interrupt the power supply to critical components like the cruise control switch and the vehicle speed sensor. Inspecting the cruise control fuse for any breaks in the metal strip is a straightforward first step. Additionally, the vacuum lines that connect the actuator to the control module can develop holes or leaks, leading to a malfunction. Testing the cruise control switches for shorts and ensuring the power circuit is intact are also vital steps in diagnosing the problem. Lastly, don't overlook the brake light connection; a malfunctioning brake light can inadvertently affect the cruise control system. By systematically checking these common failure points, you can effectively identify and resolve cruise control issues in your Chevrolet Beretta, making your DIY troubleshooting efforts more successful.

Why is the Cruise Control Not Working in a Chevrolet Beretta?

When the cruise control in your Chevrolet Beretta fails to operate, it’s crucial to address the issue without delay. Ignoring symptoms such as a blown fuse or a defective brake pedal switch can lead to more significant safety risks while driving, as cruise control is designed to help maintain a steady speed and reduce driver fatigue. Additionally, problems with the throttle control system or the ABS can not only hinder the cruise control functionality but may also indicate underlying issues that could affect overall vehicle performance. In older models, a broken vacuum line can disrupt the system, while a faulty brake light or switch can prevent the cruise control from engaging altogether. Furthermore, engine-related problems or a check engine light can signal that your vehicle is not operating optimally, which could lead to further complications if left unchecked. If your Beretta is experiencing major transmission issues or is running in limp mode, these factors can severely impact the cruise control system. Therefore, it is essential to diagnose and resolve these issues promptly to ensure your vehicle remains safe and reliable on the road.
