DTC codes / P0Bxx · Hybrid propulsion / P0B6A
P0B6A indicates that the hybrid or electric vehicle battery pack's voltage sensing circuit for the 'J' cell group is reporting a voltage lower than the computer expects, which can be caused by a faulty sense wire, a weak cell, or a problem inside the battery pack. The powertrain control module sets this code when the signal from that specific voltage sense line falls below the calibrated threshold for a set time.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
