Please Help! 2016 Rear Speed Sensor Issue

I applied the breaks yesterday and all of a sudden my dash board lit up. "skid", ABS, brake controller error, 4hi, 4lo". I have 49,000 on the truck so no warranty and the dealership just wants to start replacing anything associated with the errors that came up on their computer. I do haul my boat some but I've never hooked up the brake controller. Very frustrating this is happening on a 2016 model. Through research I've seen it could be the rear speed sensor, the rear speed sensor wiring, maybe a loose gas cap. Has anyone seen this or have any advice? I thought I would start with replacing the speed sensor.

 

The dealership said the code came up as 1) the right rear speed sensor and, 2) trailer relay. They wanted to immediately charge me $1000 and start changing parts. I could see this rabbit trail ending up costing me a lot of money for my 2016 Tundra. I'm hoping someone has already dealt with this and has some direction.

 

U need to have someone diagnose the damn truck and not throw parts at it

 

Isn't it under warranty being a 2016?

 

Not speed sensor stuff. 3 36

 

As stated 49,000 miles on it. I doubt the techs even crawled up under the truck.

 

Yep. My bad.

 

Sorry you are having problems. Ditto what @LOTSOFTOYS said. Sounds like you need to find a better dealer or a reputable independent repair shop.

 

Yes, thanks for the replies. $110 to the dealership and no troubleshooting. I did take both the rear speed sensors out yesterday evening, cleaned both, and re-installed. No change on the Christmas tree alarms on the dash. Also, I inspected the wiring as best as possible and found no issues. Today I plan to purchase the rear speed sensor from O'rielly's ($178) and change out myself. We'll see if this works. This is a 15 minute job and the dealership was going to charge $560 to do it.

 

So yesterday I replaced the right rear speed sensor and it appears to have solved my issue and caused world peace! I've drove the truck for about an hour including on the highway and no alarms.

 

Excellent job!

Its easy to freak out and imagine your wallet getting emptied. Buy yourself a code reader. Try to find yourself a good independent toyota shop. Next time this happens, see if the code reader will give you something to work with. Google the codes. Post on the forums. Use the independent shop for deeper diagnosis. Once you know what the problem is, a lot of the time its something you can fix on your own. If not, an independent shop will do the work for a fair price.

I hate the stealership.

 

I made my own for $5 in parts

 

For those with the ability...sure, most people will be happy with the $75 investment.

 

I'm not disagreeing with you. Just letting people know what I did. Its not difficult. I made it out of aluminum from the local hardware store and rivets. For tools, I used a hacksaw, file and rivet gun. Took a half hour per corner

Hello everyone! I am resurrecting this thread as it is the most directly related to something I am currently experiencing that I could find on the internet. I apologize if my etiquette is off I have not used a forum in ages since working on my car 20 years ago as a teenager. I appreciate any help and guidance.

I had this exact same issue happen a couple of months ago. Driving in the rain, pressed the brakes and suddenly the dash lights up like a christmas tree. ABS, traction control, 4hi, 4lo. The free scanners at auto zone indicated a wheel speed sensor issue, and I just took it to my local shop (I live in a small town, Dillon, Colorado) for further diagnosis.

They narrowed it down to the rear right wheel speed sensor just like the OP, and are asking for $440 to replace it for parts/labor. I also called the dealership in Denver and they said sometimes this problem stems from the wiring harness as well and could be around $600-700.

After finding this thread I am going to just pay for the diagnosis at my local shop, and replace the rear right sensor myself.

My question for you all is, do you recommend strictly purchasing the OEM sensor or would it be sensible to use an aftermarket sensor. Specifically an NGK sensor that comes with 3/year 36k mile warranty. I remember NGK having a good reputation years ago when I was more in the loop.

OEM sensor: $210
NGK sensor: $116

What do you guys think? I appreciate any advice you have, especially if you have dealt with this issue in the past.

Thank you so much for your help and guidance.

 

I broke one of mine removing it to replace wheel bearings. I got a set of 4 sensors for $25 from amazom. Chep off shore stuff but it works. When it goes bad, i have three more. Don’t always approach it this way, but in this case it is a 10 minute swap, so worth the hassle to save $200

ngk is a trustworthy brand and is likely to last just as long as oem. I would guess oem is denso, but could be ngk. Toyota uses ngk as a supplier for various parts.
