Q: What does code P2DEC mean?

Cylinder 3 Intake Valve Lift Range/Performance. P2DEC indicates that the powertrain control module has detected an abnormal range or performance from the intake valve lift system on cylinder 3, typically by comparing commanded lift to actual lift via a position sensor. The engine may be running with reduced valve lift authority on that cylinder, which can affect breathing and combustion quality.
