2008 5.7L Error code C0210 - ABS Sensor

Hello.

I am trying to fix a weird issue with my 2008 Tundra (154k) and was wondering if anyone had the same issue. The C0210 error is a fault in the Right Rear ABS Sensor. I tried swapping sensors and a new sensor and the same error is occurring.

I am using a pro reader and the sensor sees the wheel speed but when I pulled the original sensor out, it is covered in grease (foul smelling). Also I pulled the new one out today and it was also covered in the same grease a couple days after installing it. I tried both the original sensor and new sensor on the front wheel and it seemed fine (after cleaning it).

So long story short, from everything I've read would you all agree that I have a bad/leaking wheel bearing assembly back there? I am assuming the grease on the sensor is not normal. I didn't pull the other side to see but I would think the sensor area would need to be clean. It was on the front one.

Was hoping someone has been through this and confirm my suspicions as well as throw me some replacement part no's (or good quality ones from Ebay or something, I'm pretty cheap)...However, I know it won't be cheap to fix most likely.

Thanks.

 

Interesting problem Kevin and welcome to the forum!

C0210
Possible causes:
Faulty Right Rear Speed Sensor
Right Rear Speed Sensor harness is open or shorted
Right Rear Speed Sensor circuit poor electrical connection
Right Rear Speed Sensor rotor
Sensor installation
Brake actuator (skid control ECU)

Thanks P-Factor. Definitely looked at the code quite a bit.

 

Interesting that you just posted this....I have a 2008 Tundra 230K miles. Couple of months ago I got the code for the rear left ABS sensor.....pulled it and found grease. Cleaned it and code went away. Sort of knew that I had a bearing seal bad. I had the bearing and seals replaced and everything was OK. A few days ago I got a C0210 (Right rear ABS sensor) code using my FIXD code reader and phone app.....no lights on dash. I have had good results with the FIXD app so I trust the results. Found a replacement for about $28....replaced it (no grease on ABS sensor)but no change in code from my code reader. No lights on dash. Sensor harness could be a problem....but will have to keep looking. Meanwhile, I will stop at the auto parts store and see if their code reader shows this code when they scan. By the way...the bearing/seals replacement in the left rear cost about $450. Grease seems to be your problem.

 

Thanks, was the $450 for the part or the part + labor? I know they sell the assembly and it looks like it would just bolt on. Not sure if anything would have to be pressed in?

thanks.

 

That was labor and parts.....Axle has to be removed . Certain retainers are pressed on so one should replace every wear part in the axle. Parts were some distance beyond $100 .....labor is the big item.

 

Gotcha, was that Toyota's price or did you have a shop do it?

 

Do you own a multimeter? With one you can test the sensor. First for internal resistance (chances are that's not your problem) then you can test to see if it's seeing the tone ring. There's plenty of sites that will tell you how to do it. You can buy a cheap multimeter if you don't have one. Chances are the tone ring has grease on it and the sensor isn't picking it up. On the 1st get Tundras the bearing, seal, tone ring, and the race for the seal are all separate pieces. I believe that the seal might still be able to be replaced by itself but the bearing and tone ring are now just one unit. I don't think you will be able to take it apart to clean the tone ring so just replacing the seal isn't going to solve the problem and the bearing is likely to be damaged when trying to pull it apart so you'll most likely have to replace it.

 

Thank you! I am going to take it in and have a suspension guy take a good look. It is what it is. Hopefully not over $500 to fix.

 

Yep bad bearing seal. Got the parts on E-bay for cheap and had a guy press it all in for $275. So around $350 out the door to get the bearing fixed. All codes clear.

 

Might be a dumb question but I am currently experiencing the fun issue of the 4 wheel hi/lo lights flashing, abs and traction lights solid. I hooked up a code scanner even though my check engin light was not on and got the c0210 code. When people say right rear, is this passenger rear? Other forums were talking about this issue(no code) and replacing the left CV axle. So this is multiple times today that passenger/driver side designation is being provided as left and right
