Q: What does code P0B46 mean?

Hybrid/EV Battery Voltage Sense C Circuit Range/Performance. P0B46 indicates that the hybrid or electric vehicle battery pack's voltage sensing circuit C is reporting a voltage reading outside the range the control module expects for the actual pack conditions. The computer compares this sensor's signal against other voltage sense circuits and flags a performance fault when the reading is implausible, erratic, or inconsistent.
