    I got a 2011 workstar with maxxforce 11 low power and boost control solenoid open circuit spn 7312 fmi 5 code 1256. Mitchell 1 does not even have info on the code. Any diagnosis tips is appreciated. I have replaced the boost control valve due to air leak so suspicious it could be to blame.

    Probably wiring rubbed through, check the harness as best you can.
