By any chance, do you know what a Wheel Speed Sensor is? Or what VSS stands for? Some of you might say, "Well yeah, of course I know", but most of you will most likely say, "Uhm.. VSS stands for 'Vehicle Super System' " with a big smile on your face.. but I HAVE to burst your bubble, because that's not even close to what it stands for. It's okay thought, because that's what I thought it stood for! But as you can tell, I was obviously wrong. No worries, I'm here to explain. Okay?
So, a Wheel Speed Sensor is also known as a Vehicle Speed Sensor (VSS), which is a type of gauge that determines how fast your wheel is rotating when your speeding on the freeway. They usually work with Anti-Lock Braking Systems so that way if the wheel tends to be faster than it should be, the ABS can partner with it and bring the car to a slow, but sure stop. It's kind of complicated the way it works.. it has magnetic stuff, some teeth on a tone ring, and some other stuff; but I'm gonna try to simplify it as best as I can. From my understanding, there are parts that resemble teeth that move in & out of the actual sensor as the wheel moves. When each individual tooth has it's turn to move into the sensor, the magnetic field changes, then when it comes out, it returns to normal. This process repeats as often as the wheel moves. After a while, it eventually starts a pattern. Ergo, when the pattern suddenly gets out of order, the Wheel Speed Sensor miraculously works. How exciting, don't ya think?
So how does the signal get across? Well when your wheel eventually gets faster and faster when you're speeding down the freeway, the signal becomes greater and then notifies the genuine ABS control module. When this happens, your car automatically assumes that you are losing traction (which you most likely are since you're going so fast) and starts slowing down for you.
Wheel Speed Sensors, for the most part, are featured on trains; which makes sense, right? I mean, trains typically get from Point A to Point B on an already preset system. Like there's a train that I use sometimes to get to Los Angeles. I catch the train and it takes me to where I have to go, but I never see a person in the front or the back of the train controlling it when it needs to stop or go. These types of trains usually depend on these sensors for things such as traction control and preventing the wheel from sliding the wrong way. They weren't as effective back then since trains would go faster than normal; but now they are much safer for all of use to ride (just an FYI).
Wheel Speed Sensors aren't actually located on your, let's say, Ford Expedition Wheels; but they're placed somewhere near the axle. Which makes sense because isn't the axle the one that rotates the wheel? If not, I need to read some more or something; but I'm sure you know what I mean. It doesn't matter if you have a new car or old car. Well it kind of does, but if you have an older model car then you can simply ask for them to install it. It also doesn't matter if you have OEM Alloy Wheels or Factory Original Steel Rims, Wheel Speed Sensors come on your car regardless of the material on that wheel of yours.
