Q: What does code P28F6 mean?

Engine Disconnect Clutch Actuator Circuit Intermittent. P28F6 indicates that the powertrain control module has detected an intermittent fault in the electrical circuit for the engine disconnect clutch actuator, which is used on vehicles with a hybrid or dual-clutch transmission to decouple the engine from the driveline. The computer monitors the actuator circuit for expected voltage or current changes and sets this code when the signal momentarily falls outside the normal range, but not long enough to set a hard failure code.
