Hybrid/EV Battery Pack Current Sensor B Circuit Low

Where it lives

For P0B10, the sensor sits on the circuit this code reports. The description of P0B10 reports a fault at the sensor.

Check these first

• A short to ground on the current sensor B signal wire
• A failed battery pack current sensor B
• A poor connection between sensor B and the control module
• A failing hybrid battery pack
• A faulty powertrain control module input

What to do next

1. Read current sensor B on live data
2. Inspect the sensor B wiring and connector for damage
3. Test the sensor B signal wire for a short to ground
4. Compare sensor B with current sensor A
5. Replace current sensor B if the reading stays low
6. Clear the code and retest
