The P0BB2 fault code refers to the Hybrid Battery Voltage Sense ‘X’ Circuit IntermittentErra. This code is related to the HV battery in hybrid vehicles.

The HV battery is made up of 28 modules, each consisting of eight 1.2 V cells in series. The battery smart unit monitors the voltage of the battery blocks at 14 locations. If there is a voltage difference between the battery blocks that exceeds the standard, the battery smart unit detects a malfunction.

When this happens, the power management control ECU illuminates the Malfunction Indicator Lamp (MIL) and sets the P0BB2 fault code.

This code indicates an intermittent or error in the circuit that senses the voltage of the hybrid battery.
