When to remove and replace ABS wheel speed sensor?

When to remove and replace ABS wheel speed sensor?

You are causing a magnetic signal that generates electiricity through the sensor, so give it a good turn. When you do that you should have a reading from the volt meter should be at least 350 ACmV’s. If the reading is less than 350 ACmV’s, remove the wheel speed sensor and replace it.

How can I test my abs at low speeds?

To test the sensor, connect a digital voltmeter to the sensor connector. Set the DVOM to AC volts. Next, Rotate the wheel by hand speed and measure the AC in millivolts. The reading should be at least 350 ACmV’s. If the reading is between 200 and 350 ACmV’s, remove the wheel, caliper and rotor to gain access to the speed sensor.

Where is the wheel speed sensor on a Chevy truck?

Trace the wiring harness for the wheel speed sensor to the plug on the main wiring harness side just above the frame and unplug it from the main harness. Run the digital volt meter across the terminals on that end of the wheel speed sensor on each side of the truck to determine proper voltage.

What to do if your ABS sensor is distorted?

Check the sensor for flatness in multiple (minimum 3) positions/directions. If the sensor head is distorted, replace the sensor. Apply (spray) two thin coats of the specified rust penetrating lubricant (corrosion inhibitor) to the complete sensor mounting surface on the bearing hub. Allow to dry for 3-5 minutes between coats.

Where is the ABS sensor on a Chevy Silverado?

Locate the ABS sensor on the wheel hub behind the brake rotor. Alternatively, you should be able to see the sensor and pump from the backside of the wheel hub. The front of the sensor, however, is facing the back of the rotor.

Why is my ABS wheel speed sensor not working?

The compaint most commonly associated with this failure of the wheel speed sensor would be that the ABS system engages at low speed and during normal stopping or pulling into a parking spot. The problem to be fixed is rust build up between the wheel hub bearing and the wheel speed sensor plug.

Why do I need to clean my ABS sensor?

This information is relayed to a computer that will automatically pump the brakes if the sensor “sees” the wheels locking up. Over time the sensors can become dirty and cause your ABS to function only intermittently. To fix this, you need to clean the ABS sensors.

Where is the ABS sensor located on a Honda Accord?

The front of the sensor, however, is facing the back of the rotor. The ABS sensor looks like a small “L” shaped black or silver box (depending on your model year). The box will have one electrical connector plugged into the bottom of it (on the back of the sensor).
