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.
When diagnosing the non-functioning cruise control in a 1990 Ford Probe, it's crucial to follow a structured diagnostic approach that starts with the simplest checks. Begin by inspecting the fuse related to the cruise control system, as a blown fuse can easily disrupt its operation. Next, assess the cruise control switch for any signs of damage or wear, since a malfunctioning switch can prevent the system from engaging. After that, examine the vacuum lines for any leaks or damage, as these can lead to a loss of vacuum pressure, which is vital for proper cruise control function. If these initial checks do not reveal the issue, utilize a diagnostic tool to test the cruise control module for any faults. Finally, verify that the speed sensor is working correctly, as it provides essential vehicle speed information to the cruise control system. By systematically addressing these areas, you can effectively identify and resolve the issues affecting the cruise control in your Ford Probe.
When dealing with a malfunctioning cruise control system in a 1990 Ford Probe, it's crucial to understand the common problems that may 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. If the fuse is intact, the next step is to inspect the cruise control switch, as a faulty switch can prevent the system from engaging or disengaging correctly. Additionally, vacuum leaks are a frequent culprit, as they can compromise the system's functionality. Another important component to examine is the speed sensor; if it is malfunctioning, the cruise control may struggle to maintain a consistent speed. Furthermore, issues with the brake light switch can interfere with the cruise control's operation, since the system is designed to disengage when the brakes are applied. Lastly, don’t overlook the throttle cable, as any malfunction here can hinder the cruise control's ability to maintain speed effectively. By systematically diagnosing these areas, DIYers can identify and resolve the issue, restoring the cruise control functionality in their Ford Probe.
When evaluating the urgency of repairing the non-functioning cruise control in a 1990 Ford Probe, it's essential to weigh the implications of leaving the issue unaddressed. While cruise control is primarily a convenience feature, its absence can lead to increased driver fatigue, especially on long journeys, which may inadvertently compromise safety. Additionally, if you plan to sell the vehicle, having all systems operational, including cruise control, can enhance its appeal and potentially increase its resale value. Therefore, while the repair may not be critical, it is advisable to consult a mechanic for a diagnostic check. This step can clarify the underlying issue and help you make an informed decision about the timing of the repair, ensuring that you maintain both comfort and the vehicle's overall value.
