Rear Speed Sensor/Wheel Bearing

I got my Prius diagnosed after all my brake warning lights went on and stayed on. (The red BRAKE, the yellow !, the ABS, and VCS). After some research here I was thinking it was a speed sensor. I dont have the capability or equipment to test it myself, so I took it to a shop. They said it was the rear speed sensor and that is part of the wheel bearing. So they quoted me 316.50 plus tax to install a new one. I did see the rear speed sensor by itself for sale on Rock Auto, and did see them as part of the rear wheel bearing. Is it possible just to do the speed senor or for the price and labor is it just "better" to replace the bearing. Any feed back would be greatly appreciated.

 

Bisco, current mileage is 295,789

Mendel, from all the pics, I've seen of the wheel bearings it does look like its integrated into the part but rock auto does have one listing of the part separate.

 

I bought my Prius used with 189,000 miles on it and no record of any work done up to that point. I am looking at after market parts just because of cost, and the fact I won't really need it to last another 10 years. Thank you for all the feedback thus far.

 

I replaced the rear wheel bearing with a $57 Centric part. It was very hard to remove the old one. Now after the new one had been install, all my lights are still on. The red brake light the yellow ! in the circle, the ABS, and the VCS. Is there any way to turn these lights off without having techstream? Any suggestions or information would be greatly appreciated thank you.

 

Patrick Wong: That's what I have been coming up with looking through this site. Although they say it clears the history as well. But if I correctly fixed the problem turning off the lights shouldn't be a problem. If I didn't fix the problem correctly they will go on again, so it's a win win scenario correct? So is this a better course of action than going to a shop to have them turned off? Thank you for any further comments.

 

When I originally got it diagnosed I took it to a shop they charged me 100 dollars. I have been thinking about getting Tech stream so I can do a lot more diagnosis on my own. I think that would be a good investment

 

I have not reset the lights and the codes yet. As a side note I'm just curious, do the lights being on affect MPG? even with it being colder here in Wisconsin sure seems to be dropping significantly with the lights on.

 

I just had my rear brakes done a month ago and I didn't notice anything till about 2 weeks ago, so I with bisco and my mind playing tricks on me. I am all sorts of frustrated now, and I think I will rest easy with a version of Tech Stream. When I looked on Amazon I was a bit overwhelmed. Does anyone have and recommendations on which one to buy?

 

I now have an update and I need some more help. I did the repair myself with a part purchased from Rock Auto and after the repair was finished and everything was connected after I drove it the light still stayed on. I was debating jumping pin 4 and 13 to clear the codes. recently I stopped an O'Reilly Auto Parts store and they have a scanner that could check ABS codes and the same message came up that it was the rear left speed sensor. This person continued to say that's once the part is replaced that the codes clear automatically and that I installed a defective part. Now I dont know who or what to believe. So here I am posting this question to Prius Chat to try to get some real answers. Thank you.
