A wheel speed sensor because the name senses the rate of a wheel. The sensor reads the entire number of wheel rotation and informs the motive force comparable. So, you can state that it works like a tachometer. Today, we'll learn about \”how to check wheel speed sensor\” when you think it malfunctions, so the smooth driving doesn’t stop.
There is an easy and quick method to do the speed sensor test.
How To Test Wheel Speed Sensor: Stay Away From Getting Penalized
Keeping track of the rate sensor is essential as it lets the driver know about the speed. This way, he drives inside a controlled manner. In the US, you easily get penalized because the speeding tickets. These tickets affect your general driving history, which could get you in trouble while you choose a job or vehicle's insurance.
When the speed sensor works fine, you know the driving speed so you can manage it accordingly. It's, in fact, the most important thing that any driver want. Let us get towards the method of testing a speed sensor-
Prepping the Car
When you are ready to check the speed sensor, you need to organize your vehicle. Set your vehicle on the floor level and switch the engine off. Taking \”how to check wheel speed sensor\” further, use the transmission in the park settings combined with the emergency brake.
You want to use a jack to lift your car for taking out the tire. This allows testing the sensor as your vehicle gets in the correct position. Keep all the tools handy, so you don't rush around for grabbing them.
Here are the tools you need:
- Your car's manual
- Floor jack
- Jack stands
- Tire iron
- Assistant
- Voltmeter
- Flying leads
- Torque wrench

Going On with the Steps – Taking out the Connector
Get towards the wheel speed sensor once your car is high in jack, and you have removed the wheel. There, you have to locate the electrical connector near the frame from the wheel.
Disconnect the sensor wire by unlocking the security clasp and pull it away gently. This will expose the sensor terminals that you'll want for testing purposes.
Working using the Voltmeter
Those terminals that you simply exposed are going to be used with the voltmeter. You see those probes in the voltmeter, these probes ought to be attached with the terminals of the sensor. You need to utilize those alligator clips that include the meter to securely attach the sensor.
While attaching the sensor's terminals for wheel speed sensor testing, make sure you don't let the probes touch one another.
Voltmeter which has handheld probes is probably to cause the readings to fluctuate. Avoid having these probes if you want accurate readings. This can overall make the testing simple enough.
When the thing is those probes and terminals connected well, it is time to turn the AC voltage on. You are able to immediately begin to see the readings on the meter rising and down. This suggests the sensor is able to be tested.
Getting to the Test Finally
To get the readings around the voltmeter, you have to spin that wheel or the hub. The readings vary according to the rate of the wheel. Accordingly, it is definitely the readings within the meter that go down to zero once the wheel stops.
If you can see the readings appearing within the meter whenever you spin the wheel, it indicates that the sensor is working. However, if you find no reading around the meter regardless of the spinning, this implies that the sensor has gone bad, and you ought to consider a replacement.

Tip: When you can't find the sensor's wire connector, take the assistance of the driver's manual that comes together with your car.
Replacing the Wheel Speed Sensor
Once you are determined that there are no readings within the voltmeter, it means you have to switch the speed sensor. Get to the nuts or any clips holding the sensor and unscrew them. This will detach the sensor from the vehicle so that you can remove it.
Before gelling the new sensor, have a look at the area to check out any rust. Take sandpaper and scrape the surface where you stand going to place the new sensor.
Once the new sensor gets in its place, tighten it while using screws or clips provided. Test the sensor using the voltmeter, and now it ought to demonstrate the readings whenever you spin the wheel.
If you removed the brake pads and rotors to obtain the visibility from the speed sensor clear, put them back too.
This way, you need to put everything in order or assemble the parts correctly. Once you are done with the brake pads and sensor parts, it's about placing those wheels back to the hubs. Fit all of them snugly and tighten using the lug nuts using a ratchet and socket.
Make use of the jack again and get the vehicle on the place while using jack stand. Lower the automobile until it comes to the ground to the default position.
It 's time to torque the wheel or using those lug nuts to fit the wheel to the vehicle. Make use of the nuts and tighten them up making use of your hands. Once they appear to fit snugly there, use a torque wrench.
The torque wrench should be set according to the torque capacity of your vehicle. Use the manual to find your car's torque range and hang it accordingly. Now, reach those nuts and hang them even securely while using torque wrench. You ought to be completed in a minute or two!
Conclusion
In the last step, you're designed to test drive the vehicle to ensure if everything works correctly. Observe the wheel speed sensor as well or you are becoming prompted about the current speed of the vehicle. Which is how you can test wheel speed sensor along with replacing it if the sensor goes bad!
