    I have the VSC and ABS lights coming on intermintenly in dash. Not sure what is causing this. Have taken it to a auto shop, pulled codes, claimed they knew the issue, replaced a ground wire, sent me on my way. Not even 2hrs later lights were back on in dash. Seems to also be riding a lot more rough then usual.

    Any ideas, please?

    Try checking out your wheel speed sensors, see if they are in place, tight, and the electrical connections are good.

    Mechanic said he would try and re clibrate a few sensors, came back and said that it is reading as if my truck was flipping over, but while its parked, and it will not allow its self to be recalibrated. Says I need to replace the yaw sensor, and it'll cost 600-700 just for the part. Does this sound right? I am skeptical of his answer, and am not really looking to spend that much money on something unless it'll fix my problem.

    The yaw rate sensor failure sounds plausible, but I won't swear to it since I can't check the truck myself. It measures "skid" for lack of a better term. Imagine a line drawn straight thru your truck from center of front bumper to center of rear bumper. Any deviation from that center line while still moving in a straight line is your "Yaw Rate" and is used to calculate if the ABS system needs to activate to help maintain control.
