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 cruise control issues in a Mitsubishi Eclipse, it's essential to adopt a systematic diagnostic approach. Start by checking the cruise control light; it should illuminate when you activate the system. If it doesn’t, this could indicate a problem with the control module or the switch itself. Next, read any diagnostic trouble codes, as these can provide valuable insights into specific malfunctions. Pay close attention to the clutch and brake switches, as well as the cruise control stalk, ensuring they are functioning correctly and are properly adjusted. Additionally, inspect the clock spring, as damage here can disrupt the cruise control system. By methodically assessing these components, you can identify and address the root cause of the cruise control issues, making your DIY troubleshooting more effective.
When dealing with cruise control malfunctions in a Mitsubishi Eclipse, it's essential to understand the various components that could be at fault. Common issues often stem from the control module, sensors, or switches that may have failed, leading to a complete loss of functionality. Additionally, throttle actuation problems can disrupt the system, preventing it from maintaining speed as intended. Other critical components to inspect include the clutch and brake switches, which play a vital role in the cruise control operation; if these switches are faulty, they can inadvertently disengage the system. Furthermore, the ABS system, tail light circuit, and even the clock spring can contribute to cruise control issues, as they are interconnected with the vehicle's electronic systems. It's also important to ensure that the cruise control is being activated correctly, as improper activation can lead to confusion and perceived malfunctions. By systematically checking these components, DIYers can effectively diagnose and address the underlying issues affecting the cruise control system in their Mitsubishi Eclipse.
When your Mitsubishi Eclipse's cruise control system fails, it’s crucial to address the issue without delay. Ignoring symptoms such as unresponsive controls or erratic behavior can not only compromise your driving experience but also pose significant safety risks. For instance, if the cruise control is malfunctioning due to a faulty brake switch or a problem with the throttle actuation, it could lead to unexpected acceleration or difficulty maintaining speed, which can be dangerous on the road. Additionally, unresolved issues may escalate, potentially resulting in costly repairs or damage to other vehicle systems. Therefore, if you notice any signs of cruise control failure, it’s advisable to conduct a thorough inspection of the control module, sensors, and switches, as well as the clutch and brake systems. Taking prompt action can help ensure your Mitsubishi Eclipse remains safe and reliable, allowing you to enjoy your driving experience without unnecessary worry.
