These little guys actually do a pretty simple thing – they monitor how fast each wheel is spinning. They send that information to the car’s computer, which is the ABS module. It's a magnetic sensor, so it doesn’t have any moving parts to wear out, really. Just a sensor and a wiring harness. That wheel speed data is crucial for your anti – lock braking system – that’s where the ABS part comes in. If one wheel starts slowing down way faster than the others – like if you’re starting to skid – the ABS module uses the info from these sensors to pulse the brakes on that wheel. It does this really fast, several times a second, to keep the wheel from locking up and letting you maintain steering control. Think of it like a safety net for your braking. It also works with traction control and stability control systems, using that same wheel speed data to help prevent slides. A failing ABS sensor can really throw a wrench into things. You'll usually notice if one goes bad because the ABS light on your dash will come on. Sometimes it will just light up and stay on, sometimes it flashes. If it's flashing, the system is likely disabled, meaning you’ve lost the benefits of anti – lock braking. Even if it's just on solid, it's telling you something isn't right and should be checked. You might also notice longer stopping distances, or the car feeling unstable during braking, especially on slippery surfaces. It's a safety item, honestly. If you're seeing that light, it’s best to get it sorted out. We—or a place like Fixparts Online—carry a good range of them, and they’re generally pretty straightforward to replace, depending on the vehicle, of course.
