How To Test ABS Wheel Speed Sensors

In this video Mike shows how to quickly check out an abs wheel speed sensor and confirm the sensor, the wiring and the ABS module all without any fancy or expensive testing equipment. Enjoy!

@@GoTechTraining I don't have a vehicle with wheel censors but I try to help others with their vehicle problems. I'm not sure what running the information coming from the wheel on the the other side of the vehicle into the censor that has a problem is doing? Should the code be off and stay off if the wiring harness is good?

[@GoTechTraining]

That's correct MJ, if you have a code for the LF, you run the sensor signal from the RF to the LF harness side and simulate the LF sensor. This confirms the wiring and ABS module are ok. Then you're left with either a bad abs wheel speed senor or bad tone ring. ~Mike

[@peacepoet1947]

@@GoTechTraining thanks for responding to my question. Have a Merry Christmas and a wonderful New Year. I'm a DIY backyard mechanic because it's extremely expensive to bring your vehicle to someone else to fix your own vehicle. Plus you don't know what they might have done to your vehicle.

hi bud I need to cheat abs module on a 2019 golf gti. need to send pulses(signal) from right front side to left front side as making both pulses (signal) the same. could you help me with this and avoiding abs module to detect a fault? thanks in advance

[@johnlam2661]

Keep the great content coming Mike! Do you have any recommendations on service repair info for European vehicles? I primarily use Identifix and Mitchell ProDemand but info is severely lacking for European cars. It makes diagnosing or even hanging parts difficult at times. I have access to All Data but never use it because I like the layout of the other two sources better.

[@GoTechTraining]

Hi John, Sometimes if I'm in a pinch for info, I will purchase a day subscription to OEM service information. BWM TIS can be purchased for $30 a day. It seems expensive, but it saves money in the long run not searching all over trying to find accurate information. Thanks for reaching out! ~Ryan

what would cause no signal from any of the 4 sensors after an ABS module was replaced and same issue?

[@R3YNZ]

Curious on the code criteria. What is it monitoring on KOEO?

[@GoTechTraining]

Circuit integrity, it's looking for resistance in the sensor i believe. ~Mike

Mike,ignore my question, i was paying attention when i was watching. thanks.

[@harrycash8713]

I just tried to check my ohms on my 2003 Ford explorer. I'm not getting any readings. Must not produce any resistance unless the wheels turning.

[@Hybrid600]

3 out of 4 of my ABS sensors are working and all consistent except the left front one. It works but it goes up and down in speed. This is using a good Snap On scanner and monitoring the datastream. I got a new sensor and put it in. It works but the reading from it is even more erratic than the original one. There's 16,000 miles on the wheel bearing I changed in that corner. Could it be that the magnetic ring is damaged/defective? I cleaned it as best as I could and cleared the ABS dash warning but it never clears and is constantly there. The scan keeps pointing to the left front sensor. It's frustrating. Any input is appreciated, thanks.

[@humbledhands]

Check the ground cables for those sensors for damage and corrosion

[@Hybrid600]

@@humbledhands the problem all along was a bad wheel bearing magnetic stripe. Swapped it and good to go.

[@nilolee2426]

Is The car key in “on” position to get the code?

[@GoTechTraining]

Yes, to get a trouble code the module needs to be powered up. Either with the engine running or the key in the on position with the engine off. ~Mike

[@moebassidji8306]

shouldn't you also get a code for left front sensor since it is disconnected?

Could you just short wire's together and see short reported then you know wiring good. So sensor or tone ring.

[@charliemagoo7943]

On gm with digital sensor it will kill power immediately if it sees a short.

[@GoTechTraining]

Hey Ian, great question. Charlie nailed it, on GM's. Not sure about Ford, haven't tried it but i'd assume similar strategy. ~Mike

[@thomasdemarco617]

multi meter on sensor spinning wheel should show activity on AC mode

[@GoTechTraining]

On an AC style sensor that is correct. On this magneto resistive (MR) sensor, a digital square wave is produced. The sensor requires power and ground to operate. ~Mike

[@georgegautier372]

I'm about to junk my 2012 dodge charger because don't even god can fix a rear left sensor and the crappy car is in safe mode since that. Replace Sensor, Axle, ABS module, Entire ABS module, and no way. I have normal read from 4 sensors like is ok but remain saying that have issues in rear left sensor and limp mode. IDK what else to do.

[@troutjunkie7330]

Its simple till you get 90s car with very intermittent signal loss going over bumps. No codes will tell you which wheel has signal loss. Driven with oscilloscope for hours back probed to all signal wires. Gave up

[@GoTechTraining]

Hey Trout Junkie, thanks for watching! Sounds like a great diagnostic path to get the car diagnosed. Which sensor was bad? ~Mike

[@JDMChase]

eh i’d rather pay someone who needs money like you than doing any of this😂😂

[@GoTechTraining]

[@BUGDOCTOR40]

if it was a tone ring the code would't show up unless it was moving

[@GoTechTraining]

Hey, you're right, that's a great point! ~Mike

[@louiscates6975]

In that case, you would most likely have a performance or signal code rather than a circuit code

[@tomsurrey2252]

BUT, what is the problem?

[@dtran1105]

Bad tone ring only set the code while driving

[@GoTechTraining]

Hi, 100% true, we checked it so we wouldn't run the risk of discovering it after we fixed the wheel speed sensor. This ABS light was on for a while! Thanks for watching! ~Ryan
