Q: What does code P2881 mean?

Engine Disconnect Clutch Actuator Circuit High. P2881 indicates that the powertrain control module has detected an abnormally high voltage on the engine disconnect clutch actuator circuit, which is used in hybrid and some automatic transmission systems to decouple the engine from the drivetrain. The computer expects a specific voltage range during actuator operation, and a reading above the threshold triggers this code, often pointing to an open circuit, a short to power, or a failed actuator.
