Turbocharger (TC) Control System: Overview

The function of the turbocharger (TC) control system is to optimize boost pressure and, as a result, engine output under the most variable conditions. As boost pressure is controlled electronically, the turbocharger (TC) delivers full output at a speed as low as 1800 RPM which means that it provides high torque at all engine speeds. Turbocharger (TC) boost pressure is controlled by the engine control module (ECM).
