Fault Family System: Powertrain (P-Codes) 15 SAE Codes

Engine Disconnect Clutch Actuator

Diagnostic & Technical Explanation

Code P287E (Engine Disconnect Clutch Actuator Circuit/Open) concerns the engine disconnect clutch (K0) that decouples the combustion engine from the hybrid drive motor for electric driving, covering actuator circuit faults, excessive slippage, over-temperature, stuck open/closed, engagement faults, and driver over-current conditions. Causes are a worn clutch friction pack from frequent engine start-stop transitions, a failing clutch actuator motor or hydraulic piston, or damaged actuator wiring at the transmission bell housing, and hybrid-system depowering procedures apply before any internal work.

These 15 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 15 times.
