The job of the anti-lock braking system (ABS) speed sensor is to monitor wheel rotation. As it evaluates the speed, it helps figure out whether the ABS should be engaged to take over manual braking under certain conditions, such as when thereís loss of traction. When the sensor fails, the ABS may be triggered all of a sudden or may not engage at all. The brakes stop responding the way they used to. In a snap of a finger, things can get weird and out of control. Before things go out of hand, the speed sensor must be checked. If itís already defective or damaged, then this must be replaced at once. When shopping for a new speed sensor for the vehicleís anti-lock braking system, there are a couple of things to keep in mind.
Look for ABS speed sensors that are engineered to match the exact OE specs. These sensor replacements should be compatible with the make, model, and year of the vehicle. You wonít have trouble hooking them up to the anti-lock braking system. You can be sure that they wonít only be installed quite easily but will also be sending the right signals. OE sensors wonít require any modification and can be used right after theyíre installed properly. When looking for a stock replacement ABS speed sensor, take note of the OE number to make sure that you have the right component.
Take note of the specs. See if the sensor comes with a harness or wire harness extension or if itís designed as a pin or blade type. Some speed sensors come with a 2-prong connector or a couple of wires. Some may even have a wheel mounting location. All these details matter and must be taken into consideration. You may consult your vehicle manual to find the exact replacement youíre looking for.
Donít just order any ABS speed sensor without first checking its application, whether itís for the front or rear or the driver or passenger side. Take note of the sensor location, whether itís mounted on the rear axle or at the rear center.
