CIRCUIT DESCRIPTION
To control maximum turbocharging pressure the turbocharger system includes a waste gate valve controlled by an actuator. The actuator is controlled by the manifold pressure which is duty controlled by the VSV based on signals from the ECM.
If the ECM detects the below diagnosis conditions, it operates the fail safe function in which the ECM stops fuel injection.
