Q: What does code P2843 mean?

Shift Fork D Position Circuit High. P2843 is a generic transmission code indicating that the transmission control module (TCM) has detected an abnormally high voltage on the circuit for shift fork D position, which is part of an automated manual or dual-clutch transmission's shift fork position sensing system. The TCM expects the signal voltage to stay within a calibrated range as the fork moves, and a high reading usually means an open circuit, a short to power, or a faulty position sensor.
