Q: What does code P2834 mean?

Shift Fork A Position Circuit High. P2834 indicates that the transmission control module (TCM) has detected an abnormally high voltage on the signal circuit for Shift Fork A, which is the actuator responsible for selecting gears in a dual-clutch or automated manual transmission. The TCM expects the voltage to stay within a calibrated range as the fork moves, but a reading above the threshold suggests an open circuit, a short to power, or a faulty position sensor.
