Hey folks,

While I've been reading many threads discussing my issue, I have yet to find one with a definite solution yet.

My wife's Sorento (2011 EX FWD) has the three mentioned lights pop on whenever they so desire. After start up they wont go out sometimes, driving down the road, varying speeds, hot, cold weather, rain or dry....doesn't seem to matter....just come on whenever. If I shutoff the car, the lights will 90% of the time go away just to come on again later. So, I replace the brake light switch as most suggested. I'm now on my 3rd switch in as many months with the last replacement going only 2 days. Never does the car throw any codes, nor any functions that go through the switch not work when lights are on.

I've talked to the service dept of my local dealer more times than I car to count. All they want me to do is bring it in to scan for codes, and replace the brake switch for the low low price of over $150. When I tell them I let my 7 yr old daughter change the switch in less than 10 minutes, and I've done that 3 times, they still want to replace the switch. What's even better is electrical parts have "No Warranty" so I just keep buying them. At least the switches are only $15 and some change.

Also of note, Dealers are still using the same Part# switch that had the recall done a couple years ago unless you specifically ask for the other Part# switch when buying.

Okay, off my soap-box rant.

I've seen some state they have changed an ABS sensor, but my question is.....which one if the computer flags no codes?

Very frustrating especially since my wife is the primary driver and it's happening more frequently.

Did I miss anything? I guess I can replace all ABS sensors one at a time if they aren't too expensive, but I haven't prices them yet.

Thanks for letting me rant.

I have a 2012 LX. Had what sounds like the same problem. Took it to the dealer and they replaced a rear wheel speed sensor. Never had the problem again. Hope this helps....

I think I came across your thread for the issue at some point. Can you tell me what the dealer charged you and if you still have the paperwork, what the part price was itself?

Thanks

They aren't too hard to do yourself - I did them on my wife's old Accord 3 or 4 years ago. You're looking at around $100/wheel for the sensors - so $400 DIY, or probably $800 Dealership, to replace all 4 at once.

You can find them on places like Rock Auto - just look up 2011 Sorento ABS Sensor and you'll find them listed for each wheel (they are all different).

Your trouble lights seem to indicate one of them is intermittent - that's why you can't find the code. If you have one of the advanced ODBII / USB adapters you could hook it up to a laptop and run ScanTool or similar on the laptop while driving, it'll constantly talk to the ODBII system. If you're lucky you can catch the incident of the sensor causing the trouble lights as it's happening and find out what wheel it is from the code on the bus, saving you from replacing all the other sensors.

The invoice says codes C1611, C1612, C1211, and C1209. Replaced faulty right rear wheel speed sensor. P/N 52750-2B100 Hub Assy-RR wheel. All work done at no charge, billed to warranty.
Hope this helps

Thanks for the extra info guys. Of course the dealer says that I can't buy just the sensor. He said the sensor is built into the hub and the hub assy must be replaced for the low low price of Front Hub: $262.67 & Rear Hub: $375.60 That is just the part price, not including labor cost. When I asked him "then why I am looking at the speed sensor assy's online that can be bought by them self," he didn't have an answer.

I do just about all my own maintenance, so will dig into it a bit further before buying anything. Rock Auto was my first place to look because it is.....well...........AWESOME!!!!

More to come when I can get to it again.

Update.....finally had a chance to troubleshoot further

Finally got a chance to dig into this thing..........Since my vehicle was never flagging any codes, I ohmed through all 4 ABS sensors at their connections. Both front sensors were equal (approx. 650 ohms). I went to the rear sensors, disconnected the plug. I ohmed through both rear sensors (approx. 1450 ohms on the right & only 250 on the left rear).

The dealer will only replace the entire hub assy because the rear sensor is part of the hub assy (so they say). I have ordered the rear ABS sensor from Rock Auto for about $85 shipped. I should have it in the next few days and will tackle replacement this weekend. I refuse to believe the entire hub assy has to be replaced every time an ABS sensor goes bad. Why in the world would parts suppliers sell just the sensor?

I will certainly update you when I get the part and work it.

FYI,

My dealer also told me the front sensor is built into the hub assy and they only sell the hub assy and not just the sensor. Funny, once I got to troubleshooting, I found that the front sensor is a 3' wire harness with a disconnect plug in the fender well (behind the plastic) and the ABS sensor end is held into the front hub by only 1 10mm bolt. If I had to replace the front sensor, it would take me longer to remove the tire than replace the sensor.......I am so glad I have the mechanical skills to do 99% of my own maintenance.

Part shipped yesterday, so I should have an update by end of the weekend. Since it's my wife's daily driver, I'll have to wait until the weekend to work it.

Looking forward to your update. I've replaced ABS sensors on a 2000BMW 328CI, a 2001 Accord, and a '99 Silverado. They were all held in by one bolt and had a quick connect plug. I looked at the ones on my '11 Sorento because of this thread when I was swapping my winter tires for summers and it looks like they are all about the same on all 4 wheels. The worse thing that might happen is if the sensor is siezed into the housing due to road grime, corrosion, etc - you may have to destroy the old sensor to get it out, and then clean the mounting hole in the hub (which might require full disassembly of the hub - probably more work than you want to get into, but probably why Kia forces the dealers to replace the whole thing at once as a unit).

The fronts are just like you say....1 single 10mm bolt and a disconnect plug. I was able to remove them to inspect, clean, etc. Literally took longer to jack the vehicle up and remove the tire than if I had to replace the sensor. The back one is a solid ring that I assume goes around the axle and the hub just has to be removed in order to replace (have a look at Rock Auto for a pic). Still doesn't appear to be too difficult. I'll take and post pics once I get into the process this weekend.

Well crap-o-la. I got the part in today. Just for S-n-G's I ohmed it and it read 650 ohms which confirms my Left Rear is bad @ 250. However, when I looked at the connector, it is oval shaped. My 2WD model is more recatangle, so it won't connect. I got back on Rock Auto to look at pictures and sure enough, all pics show a rounded connector. However, the package mine came in was clearly marked for 4WD models. I contacted Rock Auto and they in turn contacted their vendor (Auto 7 in this case). Unfortunately, the vendor was already closed for the day, so I am a awaiting their call back with an update tomorrow. My Sorento is fully factory with no mods. So far, checking other sites like eBay and looking at pictures, everything shown is a rounded connector at the hub. eBay looks like all the sellers use the same stock photo though. Various part websites searched.....some list the sensor for "All models, while others list separate sensors depending on either AWD or FWD....wth?!?! Dealer confirmed it is a different part number for FWD and AWD models.

Still researching.............................
You'll know more when I do....stay tuned!

Okay, I think I got it all figured out. First, I'll admit I was wrong. the AWD sensor is sold separately and can be replaced alone. If I would have thought about it for half a second, I would have realized the FWD model like I have has no need for a hole for an axle end to go through...so, duh huh to me (forehead slap!)

I've attached the pics from Rock Auto to show what I mean. The Rear Hub Assy I need sells for a whopping $2 more than the sensor I ordered (which Rock Auto admitted was listed incorrectly for the FWD model). Just ordered the Hub Assy with expedited shipping so I can get back on track for a weekend repair.

Once the wheel is off, there are 4 bolts that hold the Hub Assy on, so should be less than 45 minutes total & $95 with expedited shipping to R2......compare that to $800 for dealer to R2

ALL FIXED!!

Wow, how easy it was to replace with basic hand tools. Once I had my tools together, it took a grand total of 25 minutes start to finish (that includes jacking the vehicle up, removing and installing the rear wheel.

Info: ohmed the new hub assy ABS Sensor = 1550 ohms.
Tools needed: jack, jack stand (safety first!), 4-way or whatever you have to remove lug nuts, pliers, 14mm shallow socket and a wratchet.

Step 1: Jack vehicle and set on jack stand
Step 2: Remove wheel
Step 3: Remove 2 each 14mm bolts holding brake caliper assy (set aside to avoid hanging by brake line)
Step 4: **Ensure e-brake is OFF for this. Remove 2 each #3 phillips screws holding on brake disc and pull off (might take a rubber mallet to get loose)
Step 5: Pull off retaining clip for ABS sensor and disconnect plug
Step 6: Remove 4 each 14mm bolts holding on Hub Assy
Step 7: Remove Hub Assy.

Install in reverse order.
Crank car and drive forward to make dash lights go out once and for all. YOU ARE DONE!! (See pics to follow steps)

Pics added. Sorry, I guess I missed a couple pic steps.

Also attached a pdf of Rock auto to show price range in Hub's. They gave me a full refund including shipping cost since they had a listing error for the sensor I ordered earlier in the week. Did I mention rock Auto is AWESOME!!!!

Dealership part + Labor = $800
DIY parts + 25 minutes or so = $85

A good suggestion I always have for these jobs is to use a bungee cord to hang your brake caliper from your coil spring - the hooks on a bungee fit in the caliper bolt holes perfectly - if you wrap the cord around the top of the spring it's usually just the right length to hold the caliper up nice and high out of the way and ensures you don't accidentally hang or tug the hose too much.

Great job - thanks for the pictures and follow-up. I have the AWD - this explains why my rear sensors were different than you. I totally missed where you had the FWD version. Glad it went well and now if my '11 ever decides to have an issue, I know it should be no big deal and I can save lots of moolah.

Glad I found this, same issue on my 2012 Sorento. RR sensor 340 ohms, LR 630. Ordering replacement hub assembly from Rock Auto......and yes, Rock Auto is awesome, I've been using them for years on various vehicles.

New hubs/WSS read open circuit / infinite resistance

Hmmmmm. Received the hub/sensor assembly from Rock Auto, USPS mangled the box. Checked resistance on the sensor and it read open circuit / no continuity.....I'd expected to read something. I used two different meters, switched leads, checked each pin to the hub. Contacted Rock Auto and they sent a second one, which arrived today. Checked resistance - same result. I'm thinking this is a Hall effect sensor with the ground connection made internally, so that the pins are reference voltage and signal. Would make sense to read open circuit resistance. I'm wondering if BOTH rear sensors are bad, or perhaps the lower resistance one is TOO low and the other is on its way to failing. It won't take long to install, so that will be the real test. If it takes both hubs to fix the problem, so be it, I'll let Rock Auto charge me for both and be done with it.

Sorry guys. For some reason I stopped getting notifications of replies to my thread or notifications of PM's sent to me. I just responded to the PM from jresch66. The part I used form Rock Auto was WJB WA512326 {#512326} REAR; FWD for $59.79 + shipping.

Look under your specific vehicle for:
Brake/Wheel Hub : Wheel Bearing & Hub Assembly
------------------------------------------------------------
emag,

Is yours a 4WD or 2WD model? seems strange you are reading open on both items. You should be reading something. The ABS sensor is a voltage creating generator to send signals back to the computer.

Sorry again guys. I've gone through my profile settings and unchecked/rechecked the boxes to send me email notifications.
