Pressure Regulator Valve

WARNING: This page is about a different car, the 2004 Pontiac Sunfire, 2004 Chevrolet Classic, and 2004 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

Increased torque signal fluid pressure acting on the boost valve increases line pressure at the pressure regulator valve.
