The P0B80 fault code refers to an intermittent or error in the hybrid battery voltage sense circuit. This circuit is responsible for monitoring the voltage of the battery blocks in the HV (high-voltage) battery. The HV battery is made up of 28 modules, each consisting of eight 1.2V cells in series.

The battery smart unit, which monitors the voltage of the battery blocks, detects a malfunction if there is a voltage difference between the blocks that exceeds the standard. When this happens, the power management control ECU (HV CPU) will illuminate the Malfunction Indicator Lamp (MIL) and set the P0B80 diagnostic trouble code (DTC).

It is important to address this issue promptly to ensure the proper functioning of the hybrid vehicle.
