When Do You Need To Reset Traction Control Light on Ford Fiesta?

The traction control light needs to reset when the light illuminates without any hardware issue. If the traction control light stays on due to the software issue then resetting the system can aid in resolving the issue.

As resetting the traction control is quite an easy and unpaid process, you can reset the light by yourself. If you cannot get rid of this issue even after resetting the system, that indicates there is a problem with the car hardware like sensor, wiring or complete system. 

In this case, you need to consult a professional automobile mechanic for further assistance. It’s not recommended to drive with the traction light on without being sure about the exact reason. 

Why Does My Ford Fiesta Traction Control Light Stay On Even After Resetting?

The traction control light may remain illuminated despite attempts to reset it, indicating a hardware malfunction. Different components of the traction control system may be involved in the underlying problem. Let’s take a look at them below.

Wheel Speed Sensor is Broken

A wheel speed sensor measures the speed of each wheel and transmits that information to the vehicle’s computer. (1)

The computer may not be able to accurately detect wheel slip when the sensor isn’t working properly. Therefore, the traction control system may be activated unnecessarily, resulting in the light staying on.

ABS is Faulty

Traction control and ABS typically share the same control module and internal self-diagnostics system. 

Therefore, an ABS issue can trigger the traction control light. There will be both ABS and Traction Control lights on if this is the case. 

Wiring is Defective

Damaged wiring can send incorrect or inconsistent signals to the control module as it connects the sensors, control module, and other components. 

When this occurs, the traction control system may not activate correctly, resulting in the traction control light illuminating.

Steering Rack is Bad

As part of the steering system, the steering rack converts the rotational movement of the steering wheel into linear motion that turns the wheels. (2)

In the event that the steering rack wears or becomes damaged, it may not be able to provide accurate and precise steering input, resulting in the vehicle becoming unstable and less able to maintain traction.

This instability can trigger the traction control system, causing it to activate and illuminate the traction control light.


Despite attempts to reset the traction control light, the light may remain illuminated, indicating a hardware issue. Various components of the traction control system, including the wheel speed sensor, ABS, wiring, and steering rack, may be involved.


What Sensors Cause Traction Control Light?

Wheel speed sensors, brake pressure sensors, yaw rate sensors, or accelerator pedal position sensors can cause the traction control light. If a sensor malfunctions or is non-functional, the traction control system may also activate. 

How Much Does It Cost To Fix Traction Control?

The replacement of a traction switch can cost anywhere from $111 to $125, with the total cost being both labor charges and spare parts. Labor charges can range from $56 to $71, while spare parts can cost about $54. In order to determine the overall cost of traction switch replacement, both labor and spare parts must be considered.

How Do You Clean A Traction Control Sensor?

To clean a traction control sensor, you can use warm, soapy water to scrub away dirt and a wire brush or file to remove stubborn rust or dirt. However, be careful not to damage the sensor and ensure that it dries completely before replacing it. Excessive cleaning can also harm the sensor, so proceed with caution.


That’s it for how to reset the traction control light Ford Fiesta. With the information provided, you should now be able to reset your traction control light on your own. However, it’s always advisable to consult with a qualified professional mechanic to ensure that the underlying issue is properly diagnosed and repaired. 

This will help to prevent any uncertainty or potential complications that may arise from attempting to diagnose and repair the issue on your own.
