Circuit/System Description

WARNING: This page is about a different car, the 2006 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

Exhaust flow control module (EFCM) receives throttle position sensor and RPM information via serial data from powertrain control module (PCM). The EFCM uses this information to determine if to command exhaust flow control valve solenoid ON or OFF. When commanded OFF the exhaust flow control valve solenoid allows vacuum to flow to close exhaust valve.
