P2846Shift Fork B Position Sensor Incorrect Neutral Position Indicated

P2846 means the transmission control module (TCM) has compared the signal from the Shift Fork B position sensor against the commanded gear and found the sensor reporting a neutral position when the transmission is not actually in neutral. The TCM expects a specific voltage or pulse pattern for the engaged gear, and the neutral indication falls outside that expected range, so it flags the circuit as faulty.
