What Does P3497 Code Mean?

    OBD-II Code P3497 is defined as a Cylinder Deactivation System

    In an effort to meet fuel and emissions standards, many manufacturers are utilizing cylinder deactivation systems.

If the engine's control module (PCM) determines that there is a fault in the Cylinder Deactivation System, the PCM will set code P3497.
