P0B22Hybrid/EV Battery Pack Voltage Sense D Circuit Intermittent/Erratic

P0B22 indicates that the hybrid or electric vehicle battery pack voltage sensing circuit D is reporting intermittent or erratic voltage readings to the battery energy control module. The computer detects this when the voltage signal from that specific sense circuit jumps, drops out, or behaves inconsistently compared to the other cell voltage sensors, which prevents reliable state-of-charge and cell balancing calculations.
