ABS Wheel Speed Sensor Diagnostics

A VRS type wheel speed sensor will typically have a bias voltage riding underneath the AC sign wave. In this video we learn how to use this bias voltage to find opens and shorts in the circuit.

Hey paul it’s Rene we met at the TST big event. I wanna thank you again for helping me keep my house… so I can give my kid a great place to grow up. Starting with your teachings, I was able to capitalize on becoming a diagnostician in my area. And give my family a better life.

What an awesome story! Thank you my friend

I have learnt a lot watching your videos. The things I learnt from your videos helped me get the job I have right now. I know you don't know me but I feel like we are family. Thank you very much Sir Paul Danner.

[@kenniefernandez]

Hey Paul geetings man i just learn last week that to test if the 5v is a bias voltage just hook up an incandescent test light to ground and touch that wire if it drops is a bias just using the test light as a buffer. OUTSTANDING VIDEO MAN GOD BLESS

Thanks for the tip. It's easy to forget about the simple checks.

Caleb is really doing a great job at filming and editing! I have been following for about four years and I can really see the improvements in film quality, overlay shots, audio quality etc. I also like the thumbnails. Sometimes he makes the pics of you and your brother look so funny and interesting.

[@ScannerDanner]

I'm copying this and sending your comments to Caleb. Thank you so much. I'm so proud of him and blessed to work along side him.

[@mattmiles9779]

@@ScannerDanner You are blessed! Making money and getting to work with your son. It looks like you guys have a great relationship as well. I used to work on cars with my son too. Some of the best memories of my life…Also want to add that I work for the US Navy as a civilian employee in Okinawa Japan from the Pittsburgh area. I love hearing that Pittsburgh accent. It makes me miss home. Watching your videos has helped me so much. The first ten years I worked in cars I didn’t even own a fuel pressure gauge, didn’t care about diagnostic testing much, I did almost everything by guessing. Looking back I’m actually amazed how often it worked. Now I always no for sure what parts I need. I don’t have to be scared I made the wrong call when I order a part on your tax dollars.

@@ScannerDanner Thank you for the kind words. I just want to say thanks for your appreciation, but I am not a service member. I am a civilian employee of the Navy and get paid well for what I do.

[@blueskiesmobileauto4253]

Bias voltage tug test is perfect. Used this technique on a very similar situation on 16 Dodge Dart. Funny that the butt connector outlasted the soldered repair. I think it’s sometimes very hard to get a perfect solder on very small gauge wires like abs wires but I still believe a perfect solder repair should last longer than a butt connector. To each their own! Great learning as usual!

[@cardiaglexia995]

[@ring-and-run]

Great content and a noticeable tip of the hat to Eric O. Bias voltage seems to be the root of onboard diagnostics. Cool stuff.

[@JimmyMakingitwork]

Nice find as usual Paul! These GM's are bad at the ABS harness flex points going to the front suspension, fixed so many I can't count. They sell the harness for $28 or so last time I did one. Not even worth fixing unless it's past the connector, which is rare. Bias voltage is a great tool that often gets overlooked!

[@VoltageDropDiagnostics]

Great video Paul! It was nice to finally be able to meet you at ASTE. Hopefully I was able to show you a trick or two when dealing with hybrid vehicles... the world knows that you've taught me enough over the years and I probably wouldn't have been there if it weren't for videos just like this.

[@ScannerDanner]

100% PJ! And I definitely pulled some nuggets from you 1. I learned how to recognize an engine running from an engine cranking on a hybrid. 2. I learned why a single cylinder misfire on a hybrid can sound like a bad engine lol crazy 3. I learned how to ID a shorted M2? (one of the phases of the main electric motor) 4. I learned more about regenerative braking and that it has nothing to do with the brakes There was more and that was just from you! Great to meet you too my friend. Sorry we didn't get to talk much outside of the class, but great class indeed PJ. Thanks again!

Perfect timing for this video... Wife's Jeep Wrangler has a front right wheel sensor fault... Was gonna get under there and look at the wiring, Now I will look for a bias voltage to help troubleshoot!!! Thank you!

[@ScannerDanner]

Depending on the year, your speed sensor is different. It is a magneto resistive type and they use a 12v supply to it. Here is how you test those.. kzbin.info/www/bejne/gnytiJ53fLKCnLM

Hi great Danner

[@bltoth1955]

Hey Boss, I’ve seen many broken wires without insulation damage on KZbin. How do those wires get damaged? Respect.

[@ScannerDanner]

Movement and flex of a wire over time breaks off the individual strands of wires while leaving the wiring insulation untouched. It is crazy the first time you see it.

I have a 1993 cadillac deville 4.9l, My anti-lock light is on after I changed all abs sensor on the car and I drove it and the light is still on.

GM antilock systems are garbage. I've got a 13 Silverado that has low speed abs engagement. Cleaned all the rust off the mounting surfaces, made sure the signals look clean and aren't dropping out, and still it low speed engages.
