Turbocharger (TC) Control System: Overview

WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.

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).
