Camshaft Position (CMP) Actuator System

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Oldsmobile Bravada, 2004 GMC Envoy XUV, 2004 GMC Envoy XL, 2004 GMC Envoy, and 2004 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

The Camshaft Position Actuator system is used for a variety of engine performance enhancements. These enhancements include lower emission output through exhaust gas recirculation control, a wider engine torque range, improved gas millage, and improved engine idle stability. The CMP Actuator system accomplishes this by controlling the amount of intake and exhaust valve overlap.
