Laymans terms

Your car has a supercharger that helps it go faster. This code means there's a problem with the part that connects or disconnects the supercharger, like a switch that isn't working right.

Explanation

The P25EB code indicates an issue with the electrical circuit that controls the supercharger disconnect clutch. This could mean the circuit is not performing within the expected range.

Technical description

The supercharger disconnect clutch is responsible for engaging or disengaging the supercharger based on engine demands. The P25EB code is triggered when the Engine Control Module (ECM) detects a performance issue or out-of-range signal in the circuit controlling this clutch.
