Replaced Wheel Speed Sensor Still Not Working

If you have recently replaced your wheel speed sensor and it is still not working, then it is likely due to a number of different potential issues. The most common causes of this issue include a faulty wheel speed sensor, an electrical system fault in the vehicle, or a suspension system component that has gone awry. In order to accurately diagnose and repair the issue, it is important to first inspect each of these possible causes in order to identify the root cause of the problem.

Testing Wheel Speed Sensor

When performing an inspection of the wheel speed sensor, you should first check for any visible signs of damage or corrosion on the sensor itself. If there are any signs of corrosion or damage, then this could be enough to cause the sensor to malfunction and not register correctly as it should.

To do this, you will need an OBD-II scanner or a multimeter and follow the instructions in your vehicle’s service manual.

Inspect Other Components in Your Vehicle’s Suspension System

The suspension system plays an important role in helping your vehicle maintain proper contact with the road surface by absorbing bumps and other inconsistencies as you drive. If there are any components within your suspension system that have gone awry, such as worn out shocks or struts, then this could affect how your vehicle handles and potentially cause issues with the wheel speed sensors as well. In order to inspect your suspension system properly, you may need to enlist the help of a professional mechanic who can check for worn components and offer advice on how best to repair them if necessary.

Test Other Electrical Systems in Your Vehicle

If all else fails when testing for a faulty wheel speed sensor or inspecting your suspension system components, then it could be due to an electrical fault elsewhere in your vehicle’s wiring system. It is important to thoroughly check all other electrical systems such as interior lighting circuits and engine control modules for signs of damage or corrosion which can disrupt their signals and potentially cause issues with other systems such as your wheel speed sensors. To do this properly you will need access to a diagnostic scanner which can help pinpoint exactly where any faults may lie within these systems so they can be rectified before further damage is done.
