Q: What does code P2862 mean?

Shift Fork B Actuator Circuit High. P2862 indicates that the transmission control module (TCM) has detected an abnormally high voltage on the electrical circuit that controls the shift fork B actuator, which is responsible for engaging or disengaging a gear range in an automated manual or dual-clutch transmission. The TCM monitors the actuator circuit and sets this code when the voltage exceeds the expected range, typically indicating a short to power, an open circuit, or a faulty actuator.
