The P0B8F fault code refers to the Hybrid Battery Voltage Sense ‘Q’ Circuit IntermittentError.

This code is related to the HV battery in hybrid vehicles that use nickel metal-hydride batteries.

The HV battery does not require external charging and is controlled by the power management control ECU to maintain a constant state of charge (SOC) during driving. The HV battery is made up of 28 modules, with each module consisting of eight 1.2 V cells in series.

The battery smart unit monitors the voltage of the battery blocks at 14 locations. Each battery block is composed of 2 modules. If the voltage difference between the battery blocks exceeds the standard, the battery smart unit detects a malfunction. When the malfunction detection condition is met, the power management control ECU (HV CPU) will illuminate the Malfunction Indicator Lamp (MIL) and set the P0B8F Diagnostic Trouble Code (DTC).

This code indicates an intermittent or error in the Hybrid Battery Voltage Sense ‘Q’ Circuit.

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

What are the possible causes for the automobile fault code P0B8F and how can I visually inspect them?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P0B8F could be the culprit. This code is often caused by a faulty battery smart unit or a faulty HV battery assembly. To visually inspect these possible causes, check the related wiring harness and connectors.
