DTC codes / P28xx · Transmission / P2845
P2845 means the transmission control module (TCM) has compared the signal from the Shift Fork A position sensor against the expected value for neutral and found it incorrect. The sensor reports that the shift fork is not where the computer commands it to be when neutral is selected, indicating a position sensing or mechanical engagement fault.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
