P2BE5Hybrid/EV Battery Pack Current Sensor C Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2BE5 flags current sensor C as implausible although its signal is electrically valid, for instance an offset with no current flowing or a value at odds with the other readings. Stellantis lists it, worded as current sensor C circuit performance, in bulletins 08-047-20 and 08-130-21 for the 2017-18 Chrysler Pacifica plug-in hybrid with the 3.6 litre engine: the MIL comes on, and the remedy is new software for the battery pack control module, not a new sensor. GM shows how two current readings are cross-checked: in its 2019 table P0B13 fails when sensors A and B differ by more than 10 A while both lie between -20 and 20 A, 400 of 500 samples at 25 ms, Type A. CARB demands rationality checks for hybrid inputs. Wrong current corrupts the charge estimate; circuit faults are P2BE4, P2BE6 and P2BE7.
- What you may notice
- MIL on
- Hybrid system warning
- Inaccurate state of charge or reduced electric range
- Likely causes
- LikelyBattery controller software (Stellantis Pacifica PHEV, reflash per bulletin)
- PossibleSensor offset or gain drift
- RareHigh resistance at connector or sensor ground
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
