What does code P28CC mean?

Q: What does code P28CC mean?

Clutch A Motor Position Sensor Circuit Range/Performance. P28CC indicates that the transmission control module (TCM) has detected an implausible signal from the Clutch A motor position sensor, which monitors the travel of the clutch actuator in automated manual or dual-clutch transmissions. The circuit's voltage or signal pattern falls outside the expected range for a given commanded position, so the TCM cannot reliably confirm clutch engagement.
