P2CDDCold Start Cylinder 3 Deactivation/Intake Valve Control Performance

P2CDD indicates that during a cold start, the powertrain control module detected a performance problem with the cylinder 3 deactivation or intake valve control system, meaning the valve did not respond as expected when the engine was cold. The computer monitors valve timing or lift and sets this code when the actual response deviates from the commanded value beyond a calibrated threshold.
