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.
To effectively diagnose cruise control issues in your 2002 Mitsubishi Lancer, begin with the simplest solutions before moving on to more intricate assessments. Start by checking the cruise control fuse, as a blown fuse is a common and easily fixable problem that can disrupt the system's functionality. Next, inspect the cruise control buttons on the steering wheel to ensure they are operational; faulty buttons can prevent the system from engaging. If these initial checks do not resolve the issue, examine the speed sensors, as they play a crucial role in the cruise control's performance. Utilizing an OBD-II scanner to scan for error codes can provide valuable insights into any underlying problems. If necessary, test the cruise control module to confirm it is sending the correct signals. Additionally, inspect the vacuum lines for any leaks or blockages, as these can significantly impact the system's operation. Finally, ensure that the brake and clutch switches are functioning properly, as malfunctioning switches can inadvertently disengage the cruise control. By following this structured approach, you can systematically identify and address the root cause of the cruise control issue in your vehicle.
When troubleshooting cruise control issues in a 2002 Mitsubishi Lancer, it's essential to consider several common problems that could be affecting its functionality. One of the first things to check is the fuse associated with the cruise control system; a blown fuse can easily disrupt its operation. Additionally, the brake pedal switch plays a crucial role, as it is designed to deactivate the cruise control when the brake is engaged. If this switch is faulty, it may prevent the cruise control from functioning altogether. Another potential culprit is the speed sensor; if it malfunctions, the system may struggle to maintain the desired speed. Furthermore, inspect the throttle cable for any signs of damage or obstruction, as issues here can hinder the cruise control's ability to regulate speed effectively. Lastly, vacuum leaks in the system can also lead to cruise control failure, as they can prevent the system from engaging or maintaining speed. By systematically checking these components, you can identify the root cause of the problem and take the necessary steps to restore your cruise control functionality.
When evaluating the urgency of repairing the non-functioning cruise control in your 2002 Mitsubishi Lancer, it's essential to recognize that while immediate safety risks may not be apparent, the implications of neglecting this issue can be significant. A malfunctioning cruise control system can lead to unpredictable vehicle behavior, which poses a safety hazard, especially during long drives where maintaining a steady speed is crucial. Additionally, the absence of cruise control can detract from the overall driving experience, making long trips more tiring and less enjoyable. Furthermore, if you plan to sell your vehicle in the future, a non-functioning cruise control could be perceived as a defect, potentially diminishing its resale value. Therefore, while the repair may not be an emergency, addressing the cruise control issue promptly is advisable to ensure your safety, enhance driving comfort, and protect your investment in the vehicle.
