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.
To effectively diagnose the non-functional cruise control in a 1999 Dodge Neon, start with a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Begin by inspecting the fuses and electrical connections, particularly fuse 3, as these are often the root of electrical issues. Next, examine the throttle position cable for any signs of wear or damage, ensuring it has the appropriate slack when the vehicle is off. Following this, test the cruise control switches located on the steering wheel or dashboard using a multimeter to confirm they are operational. Pay special attention to the clock spring under the steering wheel, as a malfunction here can disrupt essential electrical connections; if the cruise light on the dashboard is unlit, this could indicate a problem. Additionally, inspect the vacuum lines connected to the cruise control servo for blockages or deterioration, as these can impede functionality. It’s also crucial to check the vehicle's control module and sensors for any trouble codes that may indicate a malfunction, especially if the Check Engine Light is illuminated. Lastly, ensure the brake light switch is functioning properly, as a faulty switch can disable the cruise control system. By following this structured diagnostic approach, you can efficiently identify and address the issues affecting your cruise control system.
When troubleshooting cruise control issues in a 1999 Dodge Neon, it's essential to consider several common problems that could be at play. One of the primary culprits is a broken clock spring, which is located under the steering wheel and is responsible for maintaining electrical connections for the cruise control, horn, and airbag systems. If the horn is also malfunctioning, this could indicate a clock spring failure. Additionally, the throttle position sensor and throttle actuation cable are critical components; any malfunction here can disrupt the necessary speed signals for cruise control operation. The engine's computer, or PCM, also plays a vital role, as it manages signals to the cruise control module. If there are any discrepancies or shorts in this system, it may prevent the cruise control from engaging, often accompanied by a Check Engine Light. Another common issue is a defective brake light switch, which is crucial for disengaging cruise control when the brakes are applied. Lastly, don’t overlook the vacuum lines that support the cruise control system; these can become clogged or damaged, affecting performance. By systematically checking these components, DIYers can effectively diagnose and address the cruise control issues in their Dodge Neon.
When considering the urgency of repairing the non-functioning cruise control in your 1999 Dodge Neon, it's essential to recognize the broader implications of related issues, particularly the intermittent malfunction of the Camshaft Position Sensor. While a malfunctioning cruise control system may seem like a mere inconvenience, it is crucial to understand that the camshaft position sensor plays a vital role in the engine's performance. If left unaddressed, intermittent sensor issues can lead to erratic engine behavior, reduced fuel efficiency, and even potential engine damage over time. Therefore, while the cruise control issue may not pose an immediate safety risk, the camshaft position sensor's malfunction warrants prompt attention to prevent more severe complications. Prioritizing the diagnosis and repair of the camshaft position sensor will not only enhance your vehicle's performance but also ensure a smoother and safer driving experience.
