The most common reasons a 2001 Dodge Ram 1500 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 2001 Dodge Ram 1500 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.

What are the steps to diagnose the non-functioning cruise control on a 2001 Dodge Ram 1500?

To effectively diagnose the non-functioning cruise control on a 2001 Dodge Ram 1500, start with a systematic approach that prioritizes simpler fixes before delving into more complex issues. Begin by checking the vacuum lines, particularly the one located under the battery, as this is a common culprit for cruise control failures. Inspect these lines for any signs of damage or leaks, which may require removing the battery and tray for a thorough examination. Next, assess the brake light switch; even if the brake lights are operational, the cruise control contacts may still be faulty. A simple test involves lifting the brake pedal while attempting to engage the cruise control. If it fails to activate, replacing the switch is often a straightforward solution.

Following this, examine the electrical system by checking the cruise control switch indicator lamp. If it does not illuminate, there may be an underlying electrical issue. Carefully remove the column covers to inspect for any broken or damaged wiring, ensuring to handle airbag wiring with caution. Additionally, verify the integrity of the clockspring, although issues here are less common in older models. Inspect the cruise control module and its associated vacuum lines for brittleness or breaks, particularly at connection points. Lastly, if your truck is equipped with an automatic transmission, ensure the speed sensor is functioning correctly, as it plays a crucial role in maintaining speed. By following this diagnostic approach, you can systematically identify and address the issues affecting your cruise control system.

What are the common problems that could cause the cruise control to stop working in a 2001 Dodge Ram 1500?

When dealing with cruise control issues in a 2001 Dodge Ram 1500, it's essential to understand the common problems that may arise. One frequent culprit is vacuum leaks, particularly in the vacuum line located under the battery, which can be challenging to inspect without removing components. Additionally, the brake light switch can be a source of trouble; even if the brake lights function correctly, the cruise control contacts within the switch may be faulty, making it a relatively easy and inexpensive fix. Another potential issue is the clockspring behind the steering wheel, which can disrupt electrical connections necessary for cruise control operation if damaged. It's also crucial to examine electrical connections and wiring, especially under the steering column, as broken wires can prevent the system from working. The cruise control switch itself may be faulty, and while replacing it is a common first step, further diagnosis may be required if the problem persists. Lastly, the throttle position sensor and brake pedal sensor can also contribute to cruise control malfunctions, particularly in automatic transmissions. By systematically checking these components, DIYers can often pinpoint and resolve the underlying issues affecting their vehicle's cruise control system.

How urgent is it to repair the non-functioning cruise control on a 2001 Dodge Ram 1500?

When considering the urgency of repairing the non-functioning cruise control on a 2001 Dodge Ram 1500, it's essential to recognize that while this feature enhances driving comfort, it does not directly compromise safety. The primary safety systems of the vehicle remain intact, allowing for safe manual speed control. However, neglecting the cruise control issue could lead to more significant problems down the line. For instance, intermittent cruise control failures may indicate underlying issues such as faulty brake switches or wiring problems, which, if left unaddressed, could escalate into more severe mechanical failures. Therefore, while immediate repair may not be critical, it is advisable to diagnose and resolve the cruise control malfunction to ensure the vehicle operates optimally and to prevent potential complications that could arise from overlooked symptoms. Addressing this issue not only restores convenience during long drives but also contributes to the overall maintenance and longevity of your vehicle.
