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.
When diagnosing the non-functioning cruise control on your 1997 Chrysler LHS, it's essential to adopt a systematic approach that begins with the simplest solutions before progressing to more complex diagnostics. Start by checking the fuse associated with the cruise control system, as a blown fuse is a common and easily fixable issue. Next, inspect the wiring for any visible damage or loose connections, as faulty wiring can disrupt the system's functionality. Testing the cruise control switch is also crucial, as a malfunctioning switch can often be the culprit behind cruise control failure. Given the age of the vehicle, don't overlook the vacuum lines; check them for leaks or damage, as these can significantly impact the operation of the cruise control. Utilizing an OBD-II scanner to scan for error codes can provide valuable insights into specific issues affecting the system. If these preliminary checks do not resolve the problem, inspect the cruise control module to ensure it is receiving power and functioning correctly. Should you still be unable to identify the issue, consulting a mechanic with experience in Chrysler vehicles can provide a more thorough diagnosis and repair options. By following this structured diagnostic approach, you can effectively troubleshoot and potentially resolve the cruise control issue in your Chrysler LHS.
When dealing with a malfunctioning cruise control system in a 1997 Chrysler LHS, it's crucial to consider several common problems that could be at play. One of the first things to check is the fuse; a blown fuse can easily disrupt the entire system, rendering it inoperable. Additionally, the brake pedal switch plays a vital role in cruise control functionality, as it is designed to deactivate the system when the brake is engaged. If this switch is faulty, it may prevent the cruise control from activating. Another potential issue is a defective speed sensor, which is essential for maintaining a constant speed; if it fails, the cruise control may not function correctly. Furthermore, vacuum leaks within the cruise control system can lead to a loss of functionality, as these systems often rely on vacuum pressure to operate. Lastly, a malfunctioning cruise control module can also be a significant factor in the system's failure. By systematically checking these components, DIYers can effectively diagnose and address the cruise control issues in their Chrysler LHS.
When contemplating the urgency of repairing the non-functioning cruise control in your 1997 Chrysler LHS, it's essential to weigh the implications of neglecting this issue. While cruise control is not critical for the vehicle's basic operation, its absence can affect your driving comfort, especially during long trips or highway driving. If you often find yourself on extended journeys, a malfunctioning cruise control system may lead to increased fatigue, making it a more pressing concern. Additionally, if you plan to sell your vehicle in the future, having a fully operational cruise control can enhance its appeal and potentially increase its resale value. Therefore, while the repair may not be immediately urgent, prioritizing it based on your driving habits and future plans can lead to a more enjoyable and valuable driving experience.
