    OBD-II Code Decreased engine performance is defined as a Cylinder 10 Deactivation/Intake Valve Control Circuit Low

    In an effort to meet fuel and emissions standards, many manufacturers are utilizing cylinder deactivation systems. This system allows the engine's control module (PCM) to disable select cylinders when additional power is not needed from the engine, such as at idle or when cruising on the highway. If the engine's control module (PCM) determines that the Intake Valve for cylinder number ten is not Turning on or off the way it is being commanded, the PCM will set code P3475.
