P2BE6Hybrid/EV Battery Pack Current Sensor C Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2BE6 is set when the output of current sensor C drops below the lowest value it can deliver in normal service. Unlike its A and B siblings, the official title omits the word circuit, but the meaning is the same out-of-range low check. No manufacturer documents P2BE6 publicly. GM's test for the coarse channel of sensor A (P0AC1) gives the scale: a converted current below -573 A (ADC count under 82) for 1.6 s within 2 s fails it, Type A, one trip. A signal shorted to ground, a missing sensor supply or a broken sensor are the usual reasons. CARB requires out-of-range checks for hybrid inputs. Without this value the controller reduces battery power; the high side is P2BE7, the plausibility code P2BE5.
- What you may notice
- MIL and hybrid or EV warning on
- Reduced power, possibly no ready mode
- Likely causes

- PossibleSensor supply voltage missing
- PossibleCurrent sensor C defective
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
