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.
If the cruise control refuses to turn on at all, the actuator could be at fault. Likewise, if the cruise control stays on but does not maintain a consistent speed, the problem could be a bad actuator. In extreme cases, a malfunctioning actuator could cause the throttle to stick and prevent the vehicle from slowing down. These symptoms may point to a bad actuator. They may also point to other problems with the cruise control and related systems.
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 troubleshooting the non-functional cruise control in a 2003 Mitsubishi Eclipse, it's essential to adopt a systematic diagnostic approach. Start by checking the cruise control fuse in the fuse box, as a blown fuse can often be the simplest fix. Next, inspect the cruise control switch on the steering wheel for any signs of damage or wear, ensuring it is functioning correctly. The brake pedal switch is another critical component; since the cruise control disengages when the brake is pressed, confirm that this switch is operational and not stuck. Additionally, the vehicle speed sensor plays a vital role in maintaining speed, so verify that it is providing accurate readings. Finally, using a diagnostic scanner to check for error codes can reveal underlying issues that may not be immediately apparent. By following these steps in order, you can effectively diagnose and potentially resolve the cruise control malfunction in your Mitsubishi Eclipse.
When dealing with a malfunctioning cruise control system in a 2003 Mitsubishi Eclipse, it's essential to understand the common problems that could be at play. One of the first areas to check is the cruise control switch, as a faulty switch can prevent the system from engaging or disengaging properly. Additionally, inspect the fuses related to the cruise control system; a blown fuse can disrupt functionality entirely. Another critical component to examine is the vacuum system, as any leaks can hinder the cruise control's performance. The speed sensor also plays a vital role; if it's defective, it may provide inaccurate speed readings, leading to cruise control issues. Furthermore, the brake light switch should be assessed, as a malfunction here can prevent the cruise control from engaging when the brake pedal is pressed. Lastly, consider the throttle cable; if it is frayed or stretched, it may not allow the cruise control to maintain a steady speed. By systematically checking these components, DIYers can identify and potentially resolve the issues affecting their cruise control system.
Addressing the non-functioning cruise control in a 2003 Mitsubishi Eclipse is important, even if it may not seem urgent compared to critical systems like brakes or steering. While the immediate safety risk may be low, neglecting this issue can lead to more significant problems down the line. A malfunctioning cruise control system could signal underlying electronic or sensor issues that might affect other vehicle functions, potentially leading to safety hazards. Moreover, a properly functioning cruise control enhances driving comfort and fuel efficiency, making it a valuable feature for long trips. Therefore, it is advisable to have the system inspected and repaired by a qualified mechanic to diagnose any root causes and prevent further complications. Taking prompt action not only ensures the vehicle's performance but also contributes to overall road safety.
