DTC codes / P28xx · Transmission / P2884
P2884 indicates that the powertrain control module (PCM) has detected an open circuit in the engine disconnect clutch circuit, meaning the clutch is stuck in the open or disengaged position when it should be closed. This clutch is used in hybrid vehicles to connect and disconnect the engine from the electric drive system, and an open circuit prevents proper engagement.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
