Q: What does code P25EC mean?

Supercharger Disconnect Clutch Circuit Low. P25EC indicates that the powertrain control module has detected an abnormally low voltage or current on the supercharger disconnect clutch control circuit, which prevents the clutch from engaging or disengaging as commanded. The circuit is used to decouple the supercharger for fuel economy or to protect the engine under certain conditions, and a low signal typically points to a short to ground, an open circuit, or a failed clutch coil.
