Q: What does code P0B69 mean?

Hybrid/EV Battery Voltage Sense J Circuit Range/Performance. P0B69 indicates that the hybrid or electric vehicle battery pack's voltage sensing circuit for the 'J' cell group is reporting a voltage that falls outside the expected range or is inconsistent with the other cell groups. The battery energy control module compares this sense circuit's reading against neighboring cells and flags a range or performance fault when the signal is implausible, erratic, or stuck.
