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.
To effectively diagnose the non-functioning cruise control on a 1997 Dodge Intrepid, start with the simplest checks before moving on to more complex components. Begin by inspecting the fuse and electrical connections related to the cruise control system; a blown fuse or loose connections can often be the culprit. If the cruise control light activates when you press the button, but the system fails to engage, this indicates that the issue may lie elsewhere. Next, examine the vacuum system, specifically the vacuum hose connected to the cruise servo, ensuring that it maintains vacuum when the engine is running. A lack of vacuum could point to leaks or blockages in the hoses. Following this, assess the brake switch, as it plays a critical role in disengaging the cruise control when the brake pedal is pressed. If the cruise control does not turn off, the brake switch may need testing for proper functionality. Additionally, check the vehicle speed sensor (VSS), as it provides essential speed data for the cruise control system; a malfunctioning VSS can affect the system's operation. Inspect the throttle cable and linkages for any binding or misadjustment, ensuring they align with factory specifications. If the cruise control light illuminates but the system remains inactive, the clock spring may be damaged and should be examined. Lastly, consider the powertrain control module (PCM) and wiring connections, as issues here can also disrupt cruise control functionality. By following this systematic approach, you can effectively identify and address the underlying issues with your cruise control system.
When troubleshooting cruise control issues in a 1997 Dodge Intrepid, it's essential to consider several common problems that may be at play. Start by inspecting the electrical system, as a blown fuse can easily disrupt cruise control functionality. If the fuse is intact, look for erratic behavior in the instrument panel or other electrical components, which may suggest a broader wiring issue or a malfunctioning Power Control Module (PCM). Next, examine the steering wheel and column components, particularly the clock spring, which is crucial for connecting the cruise control switches. If the cruise control module or its sensors, such as the throttle position or vehicle speed sensors, are faulty, they can also prevent the system from operating correctly. Additionally, check the brake switch; if it fails to disengage the cruise control when the brake pedal is pressed, this could lead to persistent cruise control activation. Lastly, consider the PCM itself, as issues here can manifest as erratic behavior across multiple systems, including cruise control. By systematically addressing these areas, you can effectively diagnose and resolve the cruise control problems in your vehicle.
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.
When dealing with a malfunctioning cruise control in a 1997 Dodge Intrepid, it's essential to recognize that while the issue may not pose an immediate safety risk, it should not be overlooked. The cruise control system is primarily a convenience feature, and its failure does not directly impact the vehicle's basic operability. However, the underlying causes of the malfunction could indicate more serious problems that warrant attention. For instance, a code 34 error may suggest issues with the speed control vacuum or solenoid circuits, which could affect other components like the Cruise Control Servo. Ignoring these symptoms could lead to more significant mechanical failures, potentially resulting in costly repairs or safety hazards down the line. Therefore, while the urgency may not be high, it is prudent to investigate and address any underlying issues to ensure the vehicle's overall performance and reliability remain intact. Regular maintenance and prompt attention to any related symptoms can help prevent more severe complications in the future.
