The sensor does work on resistance... but the resistance is created by the pickups on the wheel hub assembly in relation to the abs sensor. So by spinning it will tell you if it is within a proper voltage range. That's why you have to spin the wheel. Sensor doesn't have to be dead to not be working properly. Good question though. Thanks for watching
Pretty sure this will solve my issue. 2012 f250. Felt like air in the brake lines and the same feeling in the gas petal. Service advancedtrac fault comes on.
Really hard to see shooting into the light behind the wheel. Your data helps a bunch. And knowing what AC voltage helps me to test the sensor. Just would love to see your hub and disc setup. Any 200 watt light aimed at the side your working would really help to see.
We have a 2014 Super Duty that has the same 'errrr' sound you speak of when braking, especially on left turns. I will have Ford check this out. Thanks for the vid.
@@victorcompean5745 It could fix the problem if the sensor is bad. If the hub bearing assembly is going bad the wheel speed sensor will get erratic readings and also cause issues. May be best to replace entire hub bearing assembly
Awesome work now I realize that it’s happened to me twice and not too far from driving in the watery road in Florida after a heavy rain that flooded the road I gotta stop pretending I have an f-250 boat 🙃
Just FYI, AC volt on meter is to measure alternating current, like your home. On a vehicle you should set your meter to DC volt. Since you have a battery you are measuring direct current.
+jagmechtech I am aware that vehicles use DC power for all accessories however with an abs sensor you are not measuring dc voltage because it is not hooked up to the battery. You are testing the plug that leads to the sensor, not the end that goes to the ABS controller. Then spinning the wheel to check for a possible bad sensor if that makes sense.
Good stuff i got abs sencer problems too as i wright this u awswered my? Every body telling Me i got to take the whole asle out to get to sencer mine is front hopefully it will work out too thanks next will be a cam sencer on a f250 hevy duty will be looking to see if you did any .keep it up it helps out DYS guys thanks
Thanks for sharing this video, i have a 98 f250 and the computer read that the speed sensor a is bad, but i don't know which one would that be. You know? Thank you!!
Juan Manuel Perez There are only 3 so I would start with the front ones. Usually the front ones are the most likely to go. Hub bearings start to go bad and take them out
Is it possible to just check how many ohms are going across the circuit? If it's a bad sensor the resistance should go through the roof or read open circuit. Don't have to go through all the trouble to spin the wheel.
Damn, you did all that work with a single jack holding the front end up off the ground? All the banging and pushing etc? Use Jack stands or something bro!
In the beginning could you have plugged in your scan tool while driving and seen that one of your wheel speeds was different then the others? I am having the issue with my 2006 ford E350 with the RSC alarm going off. I have no scan tool as I read that a special scan tool is needed for ABS matters. My Service RSC alarm is outrageous to drive with. Goes off every 10 minute or so
I'm trying to fix the same problem, I am told unplugging the right rear wheel sensor will disable abs/rsc/tcs I'm just not mechanical enough to figure out where the sensor is on the 2006 e350 Mechanic says it's 1800$ to fix properly so I'm screwed and the alarm bell is driving me crazy.
+Gary Letts Usually the rear abs sensor is a speed sensor on the rear differential. Not an individual sensor on each rear wheel. I'm not sure about a 2009 but I would believe it would be the same.
Why am I not getting a reading on my ABS sensor which is brand new it's the second one I returned it first ones I didn't get a reading but I'll market meeting on the second one what am I doing wrong
Ronald Hollenback Not sure why that would happen. They all have some reading when you spin the wheel. Otherwise how would the abs unit receive information from it
@@Velvethamma I have several Super Duty's and I believe it's possible to buy 4x4 hubs that don't have the ABS "gear" inside. That type won't send a signal.
