Front Wheel Speed Sensor Replacement [Jeep JK] 

Andrew Huber this is a great point. I turned the camera off and spent a while getting my hands in there and pulling it out. Gonna pin this comment!

daleintampa thanks! I'm glad this video was the one-stop-shop for you. Take care

I use a flathead and just pry it. You can also use a pair of needle nose pliers

MakeYourOwnAdventure hopefully! haha. Thanks for watching

Matthew RK I’ll get a BMW if you get a Jeep ;)

Javier Requena i appreciate that very much! Thanks!

Brian Gregory no problem, I’m glad this video helped!!

Lol I thought my truck was a lemon...same thing throwing these codes randomly. What a pain in the ass!

Noosanfamily Noosa goodluck! Glad this video helped!

1npd haha, to all my friends, i am their mechanic! it’s good business, and fun! i hope you get it all sorted out soon, have a good day bro!

Vinny Gullotta no problem! i hope everything is well with you. Have an awesome day

I had the same problem but I took my Jeep to a local Firestone dealership. They off a curtesy code scan. Unlike Autozone or Advanced Auto, Firestone's scanner will pull history codes. Drivers front was defective. Bought 1 sensor and swapped it out and problem went away.

vahid tekeste thanks v!!

Goodluck! You got this.

Pete Minter i have a video called “how to diagnose the abs light”, that might be helpful. But these stock sensors are notorious for going out, most likely the wheel speed sensors

@@developmentdivision122 Thanks Chris. If it keeps happening I may replace. How do I know which sensor might be bad?

@@appstate1996 that is also outlined in the video I talked about in the previous comment.

I don’t have a video over it, i didn’t change my rear ones. But it is pretty much the same, however i don’t think you need to take off the rotor, i think you can access it from behind. Google it, there are write ups on how to do it on the forums.

paryl thanks! And it is stable for me, it’s an old trick my dad taught me. Just make sure the wood is centered up and you’re using a good jack location, and it adds some reach to your jack. I’ve been holding out on a new jack too, I’ve been wanting a long reach, with a long handle too, the jack i have is cheap and not so great.

Joseph French if you replace the sensor, but the bearing is causing the issue, the lights won’t turn off. But the bad wheel bearing won’t ruin a new sensor.. i say just do the job at the same time, you have to take out the sensor to put in a new wheel bearing anyways.. just my .02!

RDZmichael at the time i pulled the fuses for ABS and ESP. (I have a video on how to do that) that way it shuts off abs and you have no problems. You can still brake normally just know that you won’t have active abs.

JK408CJ been about a year or so with them on, no problems at all. Good quality. Good price too.

Clint mcfarland I’m glad it helped! Have a blessed day

Josh Allwine whenever I would start driving, I could feel the Jeep applying ABS to the drivers side front. Its a really weird feeling. But its super obvious which wheel speed sensor i failing.

Safe to drive

MUDTRAIL abs, esp light would turn on and lock up the drivers side wheel.

@@developmentdivision122 that is exactly what is happening to me right now with my 17 JK

Raychel Ortiz if you go to autozone, and get them to read the OBD2 reader, it’ll give you a code most likely. From there it’ll tell you exactly which sensor is bad. But there is one sensor per wheel. I figured out by feel, and sort of a lucky guess. But getting the code (should be like U104b or something) and googling it, will help.

Neil Crocker you have to reset the computer, just disconnect the negative terminal of the battery for a couple minutes and then reconnect it. There is a sensor on each wheel, so you might’ve replaced the wrong one.

so if there is no physical damage on either how do u know which one it is...also the abs system is still malfunctioning ...ur saying if i changed the right one the computer reset should fix the system warning and work properly?@@developmentdivision122

Carmen Gonzalez just replace the rear sensors. cheap fix. also good preventative maintenance. then from there if you still have problems, then it’s a bigger issue. i would just replace the rear if the lift remains after replacing the front ones.

I just did my front, broke it when doing ball joints. Anyway I didn't even reset the computer, lights went off after about 2 foot forward driving. I had previously had similar issues as you, intermittent lights and the jeep would actually hit the brakes while taking off. Turned out the twisted pair of wires to my left rear sensor was over twisted from the factory where the harness splits to each side above the rear axle. I unwound about an inch, stripped, soldered and used marine grade heat shrink tube to seal it. No problems now for well over a year. '09 Unlimited Rubi. Hope this helps.

Ernest Sanchez sounds like an electrical nightmare going on. Check the wiring for the fan issue, check for damage on the harness. And the abs + traction is most likely a wheel speed sensor issue. Go to autozone and have them plug up an OBD2 sensor plug up to your jeep and see if it throws any codes.

Carlitos Norris yes

Raychel Ortiz not a big issue. You just won’t have functioning ABS, traction control, or cruise control. It’s not a safety issue or anything. I drove around with the lights on for a while until I fixed it.

nevermind

no danger. Just might disable ABS and traction control. If you don’t feel comfortable without ABS and electronic stability, then get a mechanic or autozone to run a diagnostic off the OBD2 sensor. You should get a code that corresponds to the faulty sensor.

MsLeelee94 alright there’s another video i have named “how to diagnose the ABS light” or something like that. And i show how to figure it out. But if it’s under warranty, have them replace them all. They all usually go bad after a couple of years anyways.

@@developmentdivision122 thank you!

One per wheel, have it tested or replace all 4

Yes safe to drive. Your abs will not work properly so don’t depend on it when driving.

I had this problem. When I flushed my radiator and went to refill it I noticed air bubbles blowing out of the radiator cap. I didnt recap it until all the air bubbles were out and now it blows scorching hot.

erwin cuevas yes, and i have video going over how to diagnose the light. But whenever my lights would turn on, my drivers side wheel would lock up. So that’s how i knew.

Chris Meacham okay i went over to your other video. I did turn the key three times. However I got the code P-2110. Which says electric throttle control. I did my research but I guess that code comes up with the check engine light. The only light I have that comes up, is the ESP/BAS on my dash board.

The Downfall of Society yup. Sensor was bad and was causing all these problems

Rodrigo Gonzalez lol i used to fly kites back in the day

I laughed at that too lol, but i wont give the fella a gard time about it bc it was a great video.

The Bearded Jeeper eventually im just gonna take out the ABS and ESP system

I haven’t done this yet but I did the rear ones n the plugs broke. So if it’s the same plug you can use the similar plugs from a chargers light plug with an easier locking tab. Both mine in rear have been “upgraded”

I was running young and wild, no primer. But the paint is VHT SP731 Caliper Paint (I picked it up from oreileys)

@@developmentdivision122 seem to be holding up well?

Seth McWilliams it sounds like you haven’t replaced the correct sensor

Chris Meacham but I’m sure I did! I did all the checks and it was showing it was the front left sensor. But when I first take off driving my downhill assist light flashes, does that mean anything too?

Seth McWilliams still a wheel speed sensor issue. The HDC (hill decent control) will flash sometimes.

Chris Meacham what do you think I need to do now? I’ve changed the sensor and that didn’t fix the problem, and heck I can’t find anything online about it

Seth McWilliams there is one speed sensor per wheel. I would try replacing each one.
