ABS Speed Sensor

We have 2,074 Items for ABS Speed Sensor In-stock.

A lot of crazy things can happen because of a faulty ABS (anti-lock braking system) sensor. For one, your brakes may not respond when you expect it to, or just be that annoyingly defective, meaning you can get into a serious accident just in a snap of a finger. Let's see, are you willing to risk your neck every time you drive? Absolutely, no sane driver would ever want to drive a car that has unpredictable brakes. That's almost equal to attempting suicide! You have to set your brakes right. And to help you with that is a high-quality ABS Speed Sensor. There are a lot of signs pointing to a faulty sensor. You may start hearing noises or feeling vibrations coming from your brakes whenever you step on the pedal. The most dangerous effect of faulty sensors is loss or sudden application of braking force. The ABS may suddenly kick in or not engage at all. Thus, braking would then require more effort and concentration. If you're not used to braking without ABS, then you may find yourself rolling uncontrollably into another car. Or worse, it may be a pedestrian crossing by. Fix your brakes with the ABS Speed Sensor right away. This small investment may save you or another person's life in the future. Countless drivers have given up the wheel after traumatic road accidents. Try not to become one of them. Make safety your priority.

ABS Speed Sensor - Quick Guide for Buyers

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.

Fit

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.

Specs

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.

Location

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.

Testing an ABS Speed Sensor - Quick, Easy Guide for DIYers

When the anti-lock braking system of your vehicle suddenly kicks in or wonít engage, this can be blamed on a faulty speed sensor. The sensor may not be giving accurate signals for the wheel rotation and speed, causing some confusion and brake problems in the process. To figure out whatís wrong with the ABS speed sensor and to confirm if itís the one causing the trouble, you have to test the it and check for corrosion or contaminants that prevent it from sending the right signals.

Difficulty level: Easy to Moderate

Tools and materials you'll need:

  • Jack and jack stands
  • Wheel blocks
  • 1/4-inch ratchet
  • 8- to 10-mm socket
  • Voltage meter
  • Brake cleaner
  • Rag

Step 1: Jack up the rear of the vehicle and support the raised portion with jack stands. The wheel blocks must be placed around the front tires. Remove the rear tires when testing the ABS speed sensor.

Step 2: Trace the point where the electrical wiring harness from the engine meets the wiring harness of the sensor. Use a vehicle manual to locate this part.

Step 3: Use a 1/4-inch ratchet with an 8- to 10-mm. socket for moving the sensor from its original position.

Step 4: Inspect the sensorís end. See if thereís something that resembles a fur ball at the end. If so, then the ABS speed sensor is probably restricted or obstructed because of contamination. To fix this, all you need is a brake cleaner. After you spray the cleaner on the sensor, remove the contaminants by wiping them off with a rag.

Step 5: Unplug the engine harness from the sensor harness. After disconnecting them, change the settings of the voltage meter to ohms. The voltage meterís positive and negative terminals must be connected to the sensorís input and output. If you see an infinity mark in the meter, this confirms that the sensor is indeed malfunctioning. The defective sensor must be replaced. If it doesnít register an infinity when set to ohms, you have to alter the settings of the meter back to volts. If the reading on the meter is over 5 volts, the sensor is about to fail. If the reading is below 5 volts, the knock sensor must be checked to see if itís corroded. You have to trace electrical connections all the way to the sensor to see if thereís any corrosion.

Step 6: Reinstall the rear tires once the ABS speed sensor has been checked and tested. Bring the vehicle back to the ground. Remove the stands and wheel chocks.
