What does code P0BA2 mean?

Q: What does code P0BA2 mean?

Hybrid/EV Battery Voltage Sense U Circuit High. P0BA2 indicates that the hybrid or electric vehicle battery pack's voltage sensing circuit, specifically the 'U' circuit, is reporting a voltage higher than the manufacturer's expected range. The battery energy control module monitors this sense line to verify accurate cell or module voltage readings, and it sets the code when the signal exceeds the calibrated high threshold, which can be caused by a wiring fault, a sensor issue, or a module problem.
