It is the sensor that needs to be replaced. You need to bring it to the dealership for repair. It would not cost more than $1000.00.

Blue smoke = burning oil. bad valves, bad valve guides, bad piston rings. Bring lot of money to dealer to fix....or just drive down to the gulf and get some of that oil floating around....you'll need some.
