Q: What does code P25EA mean?

Supercharger Disconnect Clutch Stuck Closed. P25EA indicates that the powertrain control module (PCM) has commanded the supercharger disconnect clutch to open, but the clutch remains engaged or stuck closed. The PCM detects this by comparing the commanded clutch state to feedback from the clutch position sensor or by monitoring engine load and boost pressure that do not change as expected when the clutch should disengage.
