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-functioning cruise control in your 1999 Dodge Ram 1500, start by checking the cruise control light on the dashboard; if it illuminates when activated, this indicates that the system is receiving power. Next, inspect the control module and associated sensors, as these components are crucial for proper operation. If the light does not come on, it may point to a more significant electrical issue, so checking the fuses is essential to rule out any blown circuits. Additionally, examine the speedometer and test the speed sensor located on the rear axle, as a malfunction here can directly affect cruise control functionality. Look for common issues such as throttle actuation problems or sensor failures, and don’t forget to inspect the vacuum lines and connector cables for any leaks or disconnections. By following this structured approach, you can systematically identify and address the underlying issues affecting your cruise control system, potentially saving time and repair costs.
When contemplating the urgency of repairing the non-functioning cruise control in your 1999 Dodge Ram 1500, it's essential to weigh the convenience it provides against the potential risks of inaction. While cruise control is primarily a comfort feature, its malfunction could indicate deeper issues, such as a faulty brake pedal sensor or throttle problems, which may lead to more significant complications if left unaddressed. For those who frequently embark on long highway drives, the absence of cruise control can lead to increased driver fatigue and discomfort, making the repair more pressing. Conversely, if your driving habits involve mostly short trips or stop-and-go traffic, you might find the urgency less critical. However, delaying the repair could not only diminish your driving experience but also risk further damage to your vehicle's systems. Therefore, while it may not be an immediate safety concern, addressing the cruise control issue promptly can enhance your overall driving comfort and prevent potential complications down the line.
