How to replace your ABS wheel speed sensor?
Here’s how to replace your ABS Wheel speed sensor on your car. Random ABS codes and behavior can often be broken down to a faulty sensor. When replacing struts, these sensors are often easily to damaged. This video demonstrates how to replace the ABS sensors on Toyota and Lexus vehicles, and maybe applicable to other vehicles as well.
Where is the ABS sensor on a Mercedes Benz?
Locate Mercedes Wheel ABS Sensor. Remove the front wheel and locate the ABS wheel speed sensor. Right behind the rotor, you will see a couple of cables connected to two sensors. One wire goes to the brake pads, which is the brake pad wear sensor.
What causes an ABS sensor to short out?
Damaged ABS Sensor The ABS wheel sensor monitors the wheel rotation, controlled by its computer. This sensor works as a conjunction with the wheel stator attached to axle brake rotor, bearing hub or CV joint. With time, these sensors may short out as they are subject to vibration or road conditions. 3. Faulty ABS Computer Module
Can a faulty ABS sensor be replaced on a Lexus?

Why does the ABS light come on on a new wheel?
What’s happening is that the ABS computer is seeing a different in signal strength between the new and old wheel speed sensors. It determines that the weaker signal is indicating a wheel lockup, so it falsely activates the ABS on that wheel. Or, it determines that the weak signal indicates a bad sensor, so it lights up the ABS light.
Can a wheel bearing be replaced on an ABS system?
The new style ABS systems use a magnetic encoder built into the wheel bearing, and if the wheel bearing is installed backward with the encoder facing out, it won’t take long before your ABS light is on and your stress level goes up. The sad part is, you will most likely have to replace the wheel bearing with a new one.
How do you replace ABS on a wheel?
Locate the ABS wheel speed sensor. Remove the ABS sensor bolt then pull out the wheel speed sensor. Remove the wire from the steering knuckle. Unplug the ABS wire from the connector located at the wheel well. Install the new ABS sensor on the steering knuckle and route the wire the same way as the old sensor. Connect the new ABS sensor.
Can a bad ABS sensor cause traction lights to come on?
One of the common problems that trigger Mitsubishi ABS and Traction lights to come on is a defective wheel speed sensor, also referred to as the ABS sensor. Park vehicle in a safe work area. Loosen the lug nuts but do not remove them just yet. Jack up the vehicle and remove the wheel where you have a bad ABS sensor.
Can you drive with a bad ABS sensor?
That is why in general, it is unsafe to drive a vehicle with a broken wheel speed sensor. If the wheel speed sensor becomes damaged or wears out, initially you probably won’t notice much difference in the way your car performs if your ABS light comes on unless you are driving on slippery pavement.
How do you test ABS speed sensor?
To properly test the ABS sensor you would need an oscilloscope to display the wave form. You can use a voltmeter to check for a voltage pulse when the wheel is turned. This test is not very acurate. If you received a fault for a front wheel speed sensor you can switch them from side to side. Be careful as ABS module failure is more likely.
What are the symptoms of a bad ABS sensor?
One of the basic indications of a faulty ABS sensor includes the lighting up of the ABS light or traction control light in your vehicle’s dashboard. Symptoms of a bad wheel speed sensor also include a considerable loss in traction when you are driving on slippery road conditions.
How do you test a wheel speed sensor?
One way to check a suspicious wheel speed sensor is to measure its output voltage. One way to do this is to plug a breakout box into the ABS module’s wiring harness and attach the test leads from a digital volt ohm meter (DVOM) to the appropriate pins for the WSS circuit.
How much does a wheel speed sensor replacement cost?
ABS Wheel Speed Sensor Replacement Cost The ABS wheel speed sensor replacement cost often ranges from $200 to $400 per sensor. You can expect to pay about $100 to $150 for the wheel speed sensor and another $100 to $300 for the labor.
How do you replace an ABS wheel speed sensor?
Remove the screws or bolts that hold your ABS sensor in place and pull the sensor off the hub with a screwdriver or socket wrench. Align the mounting holes on the new sensor with the mounting holes on the wheel hub for the new ABS sensor. Thread and tighten the bolts or screws.
Can a speed sensor be replaced on a car?
This sort of sensor is used for many different systems on a modern car. Anything that rotates can have a sensor of this type mounted to it so that the powertrain control module (PCM) can monitor its rotation. If the ABS speed sensor fails or does not work properly, you can replace it on your own.
What does ABS do to prevent wheel lock?
by Alibaster Smith. The anti-lock braking system, or ABS, in your vehicle helps to prevent wheel lock up though a sensor that is mounted at each wheel that monitors wheel speed.
ABS Wheel Speed Sensor Replacement Cost The ABS wheel speed sensor replacement cost often ranges from $200 to $400 per sensor. You can expect to pay about $100 to $150 for the wheel speed sensor and another $100 to $300 for the labor.
Where are the ABS sensors located on the car?
This results in fewer accidents and quicker stops. However, ABS brakes work under a system, where ABS sensors send information to the car’s computer and the computer makes the decision to activate the ABS function. These special sensors are located near the wheels and consist of two vital parts: the tone ring and the magnetic sensor.
