The most common reasons a 2000 Dodge Viper 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 2000 Dodge Viper 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.

What are the initial diagnostic steps to troubleshoot the non-functional cruise control in a 2000 Dodge Viper?

To troubleshoot the non-functional cruise control in your 2000 Dodge Viper, start by checking if the cruise control light activates when you attempt to engage the system. This initial step can help determine if the system is receiving power. Next, inspect the brake pedal to ensure it is not stuck in the open position, as this can inadvertently deactivate the cruise control. If these checks do not reveal the problem, proceed to examine the vehicle's fuses, particularly those related to the cruise control system, as blown fuses can often lead to functionality issues. Additionally, inspect the switches and speed sensor, as faults in these components are common culprits for cruise control malfunctions. For a thorough approach, consult your vehicle's manual to locate the fuse box and identify any relevant fuses that may need replacement. By systematically following these steps, you can effectively diagnose and potentially resolve the cruise control issue in your Dodge Viper.

What are the common problems that could cause the cruise control to stop working in a 2000 Dodge Viper?

When dealing with cruise control issues in a 2000 Dodge Viper, it's essential to understand the common problems that may arise. One frequent culprit is a faulty cruise control switch, which can hinder the system's ability to engage or disengage properly. Additionally, a blown fuse within the cruise control circuit can disrupt functionality, making it a straightforward fix for those familiar with electrical systems. Another area to inspect is for vacuum leaks, as these can significantly affect the system's ability to maintain speed. A defective speed sensor may also be at fault, leading to inaccurate speed readings that compromise cruise control performance. Furthermore, issues with the brake light switch can prevent the cruise control from activating altogether, while a malfunctioning throttle cable can interfere with speed adjustments. By systematically checking these components, DIYers can often identify and rectify the issue, restoring the cruise control system to its intended operation.

How urgent is it to repair the non-functioning cruise control on a 2000 Dodge Viper?

When evaluating the urgency of repairing the non-functioning cruise control on a 2000 Dodge Viper, it is essential to recognize that while the issue may not seem critical at first glance, it carries significant implications for both safety and driving comfort. A malfunctioning cruise control system can lead to unpredictable speed changes, which may increase the risk of accidents, particularly on long highway drives where maintaining a steady speed is crucial. Additionally, the absence of this feature can detract from the overall driving experience, making long trips more tiring and less enjoyable. Furthermore, neglecting the repair could potentially mask underlying mechanical issues that might affect other vehicle systems over time. Therefore, addressing the cruise control malfunction promptly is advisable to ensure not only a safer driving environment but also to preserve the integrity and functionality of the vehicle as a whole.
