What does code P0B97 mean?

Q: What does code P0B97 mean?

Hybrid/EV Battery Voltage Sense S Circuit Low. P0B97 indicates that the hybrid or electric vehicle battery pack control module has detected a low voltage condition on the dedicated voltage sensing circuit for one specific battery module or cell group, designated as circuit S. The computer compares this sensed voltage against expected values and flags the circuit as low when the signal falls below the calibrated threshold, which can be caused by a faulty sense wire, a poor connection, or an internal battery module issue.
