P0B11Hybrid/EV Battery Pack Current Sensor B Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0B11 is set when current sensor B delivers a signal above its valid range. In GM's dual-range design, channel B is the fine channel for small currents: the 2019 battery energy control module table fails it above +24 A (ADC count over 4013) for 1.6 s within a 2 s window, Type A, one trip, and the 2011 Volt table above +23 A for 175 ms within 250 ms, one trip. Toyota maps its internal code P0B0E15, excessively high or open IB1 channel voltage, to P0B11 on the 2020-25 RAV4 Hybrid, with one-trip logic and immediate MIL. An open ground, a signal shorted to the supply or a failed sensor are typical. The low-side code is P0B10, the sensor A equivalent P0AC2.
- What you may notice
- MIL and hybrid system warning on
- Battery power limited, less electric driving
- Implausible state-of-charge display
- Likely causes
- LikelyOpen signal or ground wire of sensor B
- PossibleSignal line shorted to the sensor supply or 12 V
- PossibleCurrent sensor or junction block with integrated sensor defective
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
