Engine checklight & VSC off lights came on. Took it to the dealer and later confirmed at AutoZone the code P1155. Dealer said it's the master cylinder pressure sensor; $1200 job. How likely is that?

Definitely not Master Cylinder. P1155 has nothing to do with brakes, see link Tom posted. We can't paste the cause/solution it's copyrighted
