Q: I have a 2005 volvo xc90 that I recently purchased and I get anti skid message on the dash, I have read on volvo forums it could be due to yaw rate sensor or clock spring, I have checked and it looks like there no water under the amplifier but sensor is loose not bolted to the car, could you please help,

A: Yes it is correct it could be due to bad yaw rate sensor or clock spring but if it goes to clock spring it is ver rare for it to go bad unless airbag is deployed and than clock spring needs to be replaced,  yaw rate sensor on other hand needs to be bolted to its original position, once it is in its original position and it is working message should simply go away,
