Hybrid/EV Battery Pack Sensor Module
What this part does
The battery sensor module gathers readings such as voltage, current and temperature from the high-voltage battery pack and passes them to the vehicle's control system. The system uses this data to estimate charge, protect the cells and manage power use. The battery is a high-voltage component, so work on it is for trained people. A fault may bring a warning, an unreliable charge display or reduced power.

About this page
Scan figures come only from diagnostic scans recorded through our own apps and tools. Cars are usually scanned because a symptom or warning light prompted it, so these figures describe our scan records, not how often a fault occurs in any make or model.
Notes about specific manufacturers summarise public records (NHTSA owner complaints, recalls and manufacturer service bulletins), cited under each note. They report what those records say, not our measurements, and they do not suggest that any manufacturer or vehicle is better or worse than another.
Repair time and cost estimates come from a public repair dataset and are typical ranges, not quotes.
OBD DashX is not affiliated with, sponsored by or endorsed by any vehicle manufacturer. Manufacturer and model names and trademarks belong to their owners and are used only to identify vehicles.
This page is general information, not professional advice. Have safety-critical faults (brakes, steering, airbags, high-voltage systems) checked by a qualified technician. To the extent the law allows, we accept no liability for repairs or decisions made from this page.
