Q: What does code P2D10 mean?

Engine Pre-Ignition Above Threshold - Forced Limited Power. P2D10 indicates the powertrain control module has detected engine pre-ignition events exceeding a calibrated threshold, and as a protective measure it has commanded forced limited power, often by reducing engine output or limiting boost. Pre-ignition is abnormal combustion that occurs before the spark plug fires, and when severe enough to trip this code, the computer restricts power to prevent catastrophic engine damage.
