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.
To effectively diagnose the non-functioning cruise control in your 1998 Mitsubishi Galant, start with the simplest checks before moving on to more complex diagnostics. Begin by inspecting the cruise control fuse located in the fuse box; a blown fuse is a common culprit that can easily be replaced. Next, examine the cruise control switch on the steering wheel to ensure it is operational, as a faulty switch can prevent engagement. It's also crucial to verify the brake pedal switch, which should be functioning correctly since the cruise control system disengages when the brake is pressed. Additionally, check the vehicle speed sensor, as it is vital for sending accurate speed signals to the control module; a malfunction here can disrupt the cruise control's functionality. Finally, consider using an OBD-II scanner to scan for any error codes that may provide insight into specific issues affecting the cruise control system. By following these steps, you can systematically identify and address the problem, potentially restoring your cruise control to working order.
When dealing with a malfunctioning cruise control system in a 1998 Mitsubishi Galant, it's crucial to understand the 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 disengage the system when the brake is applied. If this switch is faulty, it may prevent the cruise control from engaging altogether. 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 can significantly impact the operation of the cruise control, as they disrupt the necessary vacuum pressure. Lastly, a malfunctioning cruise control module can also be a common cause of failure. By systematically checking these components, DIYers can effectively diagnose and address the cruise control issues in their Mitsubishi Galant.
When considering the urgency of fixing a non-functioning cruise control in a 1998 Mitsubishi Galant, it's crucial to recognize the potential safety risks involved. A malfunctioning cruise control can lead to erratic speed changes, which may result in dangerous driving conditions, especially on highways where maintaining a steady speed is essential. Additionally, the comfort and convenience that cruise control provides during long drives cannot be overlooked; without it, drivers may experience increased fatigue and discomfort. Furthermore, neglecting this issue can adversely affect the vehicle's resale value. A well-maintained cruise control system is a sign of a cared-for vehicle, and addressing any malfunctions promptly can prevent further complications and preserve the car's worth. Therefore, while it may not seem like an immediate emergency, taking action to repair the cruise control system is important for ensuring safety, enhancing driving comfort, and maintaining the overall value of your Mitsubishi Galant.
