P283A indicates that the transmission control module (TCM) has detected an intermittent fault in the electrical circuit for shift fork B position, which is used to confirm the fork's engagement in a dual-clutch or automated manual transmission. The circuit's signal momentarily drops out or becomes erratic, preventing the TCM from reliably determining fork position.
