Codes C1203, C1223, C1244

2003 sequoia , I had the Trac, ABS, lights come on a few days ago. They are staying on all the time. Codes C1203, C1223, C1244 came off the scanner. Is there a deffinite answer on what the problem is? Is there anything I can do myself or is this a dealer only fix?

Just don't know where to go next.

Thanks

Took to the dealer today, they say the Yaw-Rate sensor is bad. 650.00 to fix it. They say there is no gurantee it will clear everything up and that this is the place they have to start. I don't know what to do at this point. Could the Yaw rate sensor throw these three codes? Seems unlikely.

Any help or suggestion would be awesome.

Thanks
