UPDATED AT THE END ...this has been a good solution for me so far. 2010 jeep codes -ABS -Traction ,esp-bas lights came on ..bought a 200.00 tester ran test and it came back "wheel speed sensor" , i bought one and replaced the old one but the light didn't go out ...reset codes , came back on. used your method to test the old and new one and neither one would give a reading. (which makes sense) so i ordered 2 more sensors (i will send the bad ones back) and update this comment after it is complete. OK here is the Update : on a 2010 jeep wrangler this test proved useless. I received the 2nd one put it on still didn't work so i tried this test and no signal so apparently these sensors have to have a voltage going to them to send a signal back , I traced the wires down and found a short , spliced in a new section and got signal immediately through the scanner and the error codes went out without even starting the jeep.
Should note that this only works on a PASSIVE ABS sensor. With ACTIVE sensors, you need to keep it attached to the vehicle and use fly leads to hook into the system, then turn the ignition on as voltage is required.
Hi mate, thanks for the video, can I ask where you got the test lead long reach sprung crocodile/ alligator clips that you used on the sensor from? They are awesome....
Jeff Gagnon I usually do a continuity test from the end of the connector to the furthest part of the harness(pcm) to verify if the harness itself is causing the abs light to come on...
Can you only really do a continuity test for wiring seeing as the wiring is only relaying the voltage signal back to the ecu..? I guess i could test the same way at the end of the witing at the ecu.. just spin the wheel and if it doesnt measure close to the same then is wiring..
If the wheel sensor is bad, and I go to live data for abs system on a professional scanner, will the bad sensor be showing speed for that wheel? Shouldn't one of the wheels be staying at zero mph when the car is moving if a wheel sensor is bad?
Depends on how the sensor broke.. it could be gunked up and just reading out of the programmed good range causing the abs light to come on.. there could be a tooth missing on the tone ring just as well and be showing a difference in speed..
I get trans. Failsafe prog. On my 2002 x5 3.0 For couple sec. I was thinkn is my abs module bcuz i got 3 ligths on (DSC,ABS and brake in yellow ligths u think can only be this 2 sensors on wheels??
What if there's a dead spot or a drop out I don't think that test says weather its bad or not with out a scope it's not 100% just my opinion but thanks for taking the time to make the video and no disrespect by any means just saying it's alot to it for instance it's so easy to get burned. Example test that you did checks out then next step wire integrity and harness if they check out last check powers and ground at abs module before you call a 400 abs module and all long there was a dead spot in the abs wheel sensor it happens alot
Not exactly mate as it may not be fitted into hole properly. The mark on axle being the pickup might be damaged. The sensor may be damaged itself so figures not as expected. To just see figures is not enough.
hello help me with a problem i have a 2 whire abs sensor that is broken and i bought a new sensor and i tested the new sensor by pluging in the electrical connection but without mounting the sensor on the wheel to see if the abs light goes off when delleting the error codes but the light stays on is it posible that i have to mount the sensor on the wheel to test it i am testing it stationary . thoes the electrical polarity of the 2 whire sensor matter? or if it is not on the wheel when stationary . does it have to be near the tone wheel for the ecu to test it if it is stationary? thank you waiting for an answer
Hmmm that is a tricky problem. If you click this link our automotive experts are online ready to help all for free! www.2carpros.com/questions/new Thank you so much for watching!
2CarPros Curious as to why ignition on, this test is for the speed sensor only... I mean, you should be able to bench test a hub, so i dont think the ignition needs to be on...
If you disconnect the cable from the wheel sensor and hook your meter to that Cable therefore the sensor and the cable have no way of reading each other so when you’re spinning the wheel there’s no way that will work
How does someone check the sensor that goes into the brake system? I have an 03 is300 and my tech changed my wheel bearings and all of sudden I'm getting an abs light ..... He told me to change the two abs sensors.. why would I do that? When they were working.... I want to test them before I toss more money into my car 80.00 for two sensors.
Same here… I am wondering if the mécanicien did put the sensor correctly. He did a big job on the back and since then, the ABS, 4x4 light came on.. he told me that he is not working with ABS.. maybe this is why…
I love this. No drug out intro. No rambling about how to jack up the vehicle and remove the wheel and tire. Right to the point.
Thanks for watching!
AyyeeeeeeMEN! TO THAT. Exactly what I needed to know
No shit right! Prob why it's at the top of my search.
Great video. No BS run around, just straight to the point. Thank you for this

Yes this is exactly right,testing an active sensor witha multimeter is much harder.
Hi mate, thanks for the video, can I ask where you got the test lead long reach sprung crocodile/ alligator clips that you used on the sensor from? They are awesome....
Is that the harness to the engine side or the one coming from the upper wheel well that the and sensor and cable goes behind the wheel into the hole?
Love it, quick simple right to the point
What about testing the other end of that connector? (The one going to the car instead of the hub) is it simply a resistance test?
Jeff Gagnon
I usually do a continuity test from the end of the connector to the furthest part of the harness(pcm) to verify if the harness itself is causing the abs light to come on...
Most modern sensors are hall effect type. This is only a good test on the older ac inductive type. Still a good test but pretty outdated
Can you only really do a continuity test for wiring seeing as the wiring is only relaying the voltage signal back to the ecu..? I guess i could test the same way at the end of the witing at the ecu.. just spin the wheel and if it doesnt measure close to the same then is wiring..
Continuity test will not tell you if sensor is producing voltage. Sensor could be dirty.
nice but how do you test the rear axel sensor?
The same..? Jack up the rear and have someone hold 1 tire still if it’s an open diff
Thanks this will help me!!
Awesome! Thanks for watching!
if the wheel sensor is damage, will it cause to make the dashboard off?
Anyone got a link to those connectors
If the wheel sensor is bad, and I go to live data for abs system on a professional scanner, will the bad sensor be showing speed for that wheel? Shouldn't one of the wheels be staying at zero mph when the car is moving if a wheel sensor is bad?

@@Z-Ack It wasn't a bad sensor because I replaced them all and it did not solve the problem
Will this abs sensor test work on motorcycle abs sensors as well?
for passive type sensors only
It's best to check the resistance of the sensor to make sure it's within range.
yeah, he totally left that out.
Yeah just because the sensor "works" does not mean it is sending the right data.
@@JC-qi5bn what is the next step to know ?
Does the ignition need to be on?
Does this work on a 93 yukon and a 2003 mustang?
will this work on a 2004 Honda Accord?
This IS a Good way to check, but on a Front wheel drive car, it is kind of hard to spin the wheel with axles still attached!!
Remove the CV axle from the hub then it can spin freely. Thanks for watching!
Neutral…. ……
What probes are those 👀👀
I get trans. Failsafe prog. On my 2002 x5 3.0 For couple sec. I was thinkn is my abs module bcuz i got 3 ligths on (DSC,ABS and brake in yellow ligths u think can only be this 2 sensors on wheels??
I get like 3 or 4 times "check brake linings" on last year
thank you 🙏🏽
How do i know if my car has active abs or not? I have a 94 acura integra LS. Just asking before i try this and realize its not. Thank you
I'd bet it does for the front brakes at least. Just look for an ABS pump, follow the lines from the master. Thanks for watching!
abs sensors can still be bad n give a reading, u have to make sure its in spec or matches the other ones
Should I set AC or DC to test voltage for the auto or vehicles
Always DC for cars. Thanks for watching!
what is the type of sensor bro
What if there's a dead spot or a drop out I don't think that test says weather its bad or not with out a scope it's not 100% just my opinion but thanks for taking the time to make the video and no disrespect by any means just saying it's alot to it for instance it's so easy to get burned.

Tone ring

The sensor has to have a resistance that would indicate if it is ok.... can you tell me how many ihm i must measure?
clear and concise!

thank you for helping nice videos good chanel
2car where did u get those long alligator clips that will fit inside my GM Wheel sensor plug? thanks for any help
Just curious, does it matter whether or not the ignition is On (not w/the engine running) or Off?
I would go with the ignition on just to be save and eliminate a variable. Thank you for watching!

Curious as to why ignition on, this test is for the speed sensor only...
I mean, you should be able to bench test a hub, so i dont think the ignition needs to be on...
Correct.
ignition does not need to be on.
This way of testing it doesn’t matter if the vehicle is on or off because it’s not hooked up lol
If you disconnect the cable from the wheel sensor and hook your meter to that Cable therefore the sensor and the cable have no way of reading each other so when you’re spinning the wheel there’s no way that will work
He’s checking the sensor. Looks like the sensor has a short extension cable. I thought the same thing, but then figured it out.
appreciate the video! Thanks for showing us
Mine is built in the wheel barring... how do i check it?
How does someone check the sensor that goes into the brake system? I have an 03 is300 and my tech changed my wheel bearings and all of sudden I'm getting an abs light .....

Thank you
How do you know if that's a possible problem? Will the abs light come for sure on if there's a problem with that system?
graprilapril1 g to to go
around
ABS light would be on if one or more of the sensors wasn’t providing data to the ABS control module.
To access sensor do you have to remove the wheel?
Technically no. But it is easier to just remove the wheel. Thanks for watching!
@@2carpros OTOH easier to spin fwd with wheel on.
Nice!!! thank you. Very much
Thank you for watching!
Thank you very much
Thanks for watching!
So is this the wire from the car or from the sensor? If if it’s from the sensor does it produce its own voltage? I am confused.
from the sensor. by spinning the wheel hub it creates voltage
Thank you very much saved me buying a scanner

why are my readings 2.0 on Vac at 200
oh my god. thank you so much.
Glad you found it helpful!
thankyou very much excellent
Thank you for watching!
Cool, thanks
Thanks for watching!
This doesnt work on newer digital sensors, this is an old analog sensor that produces its own current
I hope this works for my 14 BRZ
So every other video I have watch on this they are checking resistance.
This doesn't test for a rusted reluctor ring that will cause the sensor not to work PROPERLY.
No shit, it doesnt test for a bad ecu either which could have a short on the board which can throw the light also..
@@Z-Ackinfuser but just to make this test, you just remove this possibility and move over the next test , no?
🎉
Voltage thing.
My light didn't come on until I had my brakes done and rotors turned.
Same here… I am wondering if the mécanicien did put the sensor correctly. He did a big job on the back and since then, the ABS, 4x4 light came on.. he told me that he is not working with ABS.. maybe this is why…
dmm is too slow to measure abs sensor voltage
This how to test passive abs sensor only. Active sensor rely on 12v to supply a hall effect sensor.
