In the case of selecting a turbine housing with a small area for the purpose of supplementing the lack of torque, the gasoline engine may create knocking in high speed. This device secures a solution to prevent this type of problem, where the exhaust gas is by passed at the turbine entrance that restraints the turbine revolution and provides the most suitable boost pressure.
ECM sets DTC P0246 if the ECM detects that wastegate solenoid valve control circuit is short to battery or open.
