My ABS, TRAC, and VSC lights illuminated when I cut through the speed sensor wire. It took about 15 minutes to replace BUT it cost about $150 from an online retailer. It is a simple sensor connected to the hub assembly. It is only held in with a couple of bolts. I didn't have to clear the codes afterwards.

 

I'm sure an independent shop can do it for cheaper than $700. At our shop we would use a bearing like a Timken or SKF who probably built the thing for Toyota in the first place. I believe I bought the bearing for my Scion xA in the $150 range (although that was at cost). Even if it was $250 retail, maybe labor would be $150. It's only 4 bolts that hold the thing on but a lot of times they get stuck on there and you have to bang them off without pulling the dust shield and everything else off with it.

 

yes, they are only in by 4 bolts but the assembly is also pressed in there.
when I did one it was $270 for the part and 2hrs labor. real PITA

 

It's not pressed in there really. On a brand new car it would probably just fall out when you take the 4 bolts off. But rust loves to build up on them and make them stuck. Why Toyota has no come up with a better design I don't know.

 

google "Toyota wheel speed sensor hub assembly" that's what the part is and looks like

 

This is a common failure and very easy to test, if there is no resistance on the connector, the sensor has gone bad. I don't know the exact resistance on your car but generally they are around 1500 ohms. But it doesn't really matter because when they fail, almost always they fail to an open circuit.

Autopartsway.com hs the part for $165, this is the exact same part that is in the car made by NSK. Here is one on Ebay for $141 by Beck/Arnley, no idea on the quality. To replace you probably have to remove all the brake components, then 4 bolts. The hub may or may not come off easily. If rusted on, it can be very difficult to remove and may require an air chisel.

 

2009 ABS wheel sensor problem

The problem for me is the plug & socket corrodes which destroys the pins and it quits working, I HAVE REPLACED ALL OF THE SENSORS, ONE AT A TIME, VERY EXPENSIVE.

I also had to replace the spiral cable for the drivers air bag, but Toyota has only now started a recall for this issue and still want me to take it in for repair because the cable the Toyota dealer installed 2 years ago, has a different part # from the recall part.

I AM PISSED OFF THAT TOYOTA WILL NOT DO A RECALL ON THE WHEEL SENSOR, IT'S THE BRAKES STUPID, WHAT IS MORE SAFETY RELATED?????
