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.
Addressing a malfunctioning cruise control in a 2011 Ford Flex is not just a matter of convenience; it is a critical safety concern that should be prioritized. Ignoring symptoms such as unresponsive controls or erratic speed adjustments can lead to dangerous driving situations, increasing the risk of accidents. Additionally, unresolved issues may escalate, resulting in more extensive and costly repairs down the line. For instance, a blown fuse or damaged wiring, if left unchecked, could affect other vehicle systems, compounding the problem. Therefore, it is essential to diagnose and repair any cruise control issues as soon as they arise to ensure safe driving conditions and maintain the vehicle's overall functionality. Taking timely action not only protects you and your passengers but also helps avoid further complications that could arise from neglecting these critical safety features.
To effectively diagnose a cruise control issue in your 2011 Ford Flex, start with the simplest checks before moving on to more complex diagnostics. Begin by inspecting the cruise control module, as malfunctions here can often be the root cause of the problem. Next, examine the cruise control buttons on the steering wheel for any debris or damage that might prevent them from functioning properly. It's also crucial to verify the brake pedal switch and fuses, as a defective switch or blown fuse is a common culprit behind cruise control failures. If these components check out, look for any communication issues between the cruise control module and other systems in the vehicle, as these can disrupt functionality. Finally, inspect the throttle actuation system to ensure it is operating correctly, as any issues here can also affect cruise control performance. By following this structured approach, you can systematically identify the underlying cause of your cruise control malfunction and take the necessary steps to resolve it.
