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.
A faulty cruise control module will simply result in deactivation of cruise control settings. This is because a detected error in the cruise control system could lead to hazardous driving conditions, so the module will be disabled, and the cruise control system warning light will be displayed. This will be a different message depending on make and model, and a warning light or message may be displayed on the driver instrument cluster.
To effectively diagnose the non-functioning cruise control in a 1990 Chrysler Imperial, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the fuse associated with the cruise control system, as a blown fuse is a common and easily fixable issue that can halt functionality. Next, evaluate the cruise control switch to ensure it is operational; a malfunctioning switch can prevent the system from engaging. Following this, examine the vacuum lines for any signs of leaks or damage, as these can significantly impact the performance of the cruise control. If these initial checks do not resolve the issue, proceed to test the cruise control module, which may require repair or replacement if found defective. Additionally, verify the speed sensor's functionality, as a faulty sensor can disrupt the system's ability to maintain speed. If these steps do not yield results, consulting a mechanic with experience in Chrysler vehicles can provide further insights and solutions. By following this structured diagnostic approach, you can efficiently identify and address the underlying issues affecting your cruise control system.
When troubleshooting the cruise control system in a 1990 Chrysler Imperial, it's essential to identify the common problems that may be causing it to malfunction. Start by checking the fuse, as a blown fuse can disrupt the entire system and prevent it from functioning. If the fuse is intact, the next step is to examine the cruise control switch; a faulty switch can impede the system's ability to engage or disengage properly. Additionally, be on the lookout for vacuum leaks, which can lead to a loss of pressure necessary for the cruise control to operate effectively. The speed sensor is another critical component to inspect; if it is defective, the cruise control may struggle to maintain a consistent speed. Lastly, don’t forget to check the brake light switch, as any issues here can interfere with the cruise control's operation, since it is designed to disengage when the brakes are applied. By methodically assessing these components, you can effectively diagnose and resolve the cruise control issues in your Chrysler Imperial, leading to a more enjoyable driving experience.
When it comes to the non-functioning cruise control in a 1990 Chrysler Imperial, understanding the urgency of the situation is crucial for any DIY enthusiast. While the malfunction may not present an immediate safety hazard like brake or steering issues, it can still lead to significant inconveniences and potential long-term effects on your driving experience. A malfunctioning cruise control can result in increased driver fatigue during long trips, as maintaining a constant speed becomes more labor-intensive. Additionally, neglecting this issue may lead to higher fuel consumption, as the driver may inadvertently accelerate or decelerate more frequently without the assistance of cruise control. Therefore, while it may not be the top priority compared to other mechanical problems, addressing the cruise control issue promptly is advisable to enhance the overall functionality and comfort of your vehicle. Taking the time to diagnose and repair this feature can ultimately lead to a more enjoyable driving experience, especially on highways or during extended journeys.
