How To Repair A Right Rear Wheel Speed Sensor On A 2010 Hyundai Santa Fe

All anti-lock equipped vehicles are designed with a wheel speed sensors (WSS), ane at each wheel. A stator ring is so used with the sensor which attaches to the brake rotor, CV joint, rear axle or bearing hub. This stator band has many metal "teeth" which create a magnetic field that is congenital up and so complanate with the help of the magnetic sensor. This generates AC voltage which is then picked upwardly past the computer.

The faster the stator ring spins the more than voltage is generated. To determine if a sensor has failed there are one of two methods that tin be used. Connect a code tool to pin signal the sensor, or bank check them manually. These sensors are subject to road conditions and vibrations which tin cause them to curt out and stop working. Follow the guide below to perform a sensor test using a voltmeter.

Earlier Yous Begin

Start once you have determined you are going to fix the problem, park the auto on level ground with the manual in park and the emergency brake prepare and the engine turned off.

Step 1: Locate and Remove the Connector

Locate the electrical connector from a particular the wheel speed sensor which is near the frame in the cycle well in most cases. Don't exist confused by other wiring harnesses that may atomic number 82 downwards to the bike such every bit the brake pad clothing sensor. Once located, disconnect the sensor wire at the connector by releasing the safe clasp and gently pulling it apart.

The previous step will uncover the sensor electric terminals which is what you lot will exist using for testing proposes. The voltmeter probes will be fastened to these terminals.

Footstep ii: Voltmeter Prepare Up

Using a voltmeter with alligator clips attach the voltmeter leads to the sensor. Be sure to non allow these examination probes to touch together or the sensor will not test properly. Endeavor not to use hand held probes because they can wiggle causing the voltmeter readings to fluctuate which makes testing more hard and tin can offset the test.

Once the leads have been connected ready the meter to Air conditioning alternating current voltage.

The meter will usually indicate AC voltage by a wave symbol. Once the meter is turned on information technology will fluctuate down to zero volts. Now the sensor is fix to exist tested.

Please lookout this video of the chore being done, then continue down the guide to glean additional helpful information.

Step three: Perform Exam

While observing the voltmeter spin the wheel or hub to create voltage. This voltage volition vary according to the speed in which the hub or wheel is spun. As the hub begins to spin the voltage will rise so subtract equally it stops.

Slowly spin the hub or axle which will produce the voltage, if no readings tin can exist found the sensor has failed and replacement is required.

This is a typical reading from a wheel sensor. Configuration of the sensor mounting is different for each manufacturer but follow the aforementioned operation.

In the image beneath a stator ring or as it is sometimes called a reluctor can exist located inside the begetting hub, rear axle housing, or on the CV joint itself.

Slowly rotate the ring to check it for impairment or missing teeth. Cycle sensors are magnetic and then bank check for metal shavings effectually the sensor which can hinder performance.

If y'all have gone through all these steps and you still have a code for ane of the sensors the only other possibility is an open circuit somewhere in the wiring which tin can be found by a pin to pin bank check which test of the wiring.

Yous volition need to use a specific wiring diagram with a voltmeter gear up to ohms of resistance to check each wire from end to end. This will help detect a broken or shorted wire, one time repaired it should turn the light off. This is an example of an ABS sensor wiring diagram.

Conclusion

Exist observant when first driving the vehicle after testing the ABS organization. Listen for abnormal noises or operation issues that could indicate a problem which will need further inspection.
