DTC codes / P2Bxx · Hybrid propulsion / P2BE5
P2BE5 indicates that the hybrid or electric vehicle battery pack current sensor C circuit is reporting a range or performance fault, meaning the voltage signal from that sensor falls outside the expected window or behaves erratically during key-on or self-test. The battery energy control module monitors this sensor to calculate pack current for state-of-charge and power-limit calculations, and it sets the code when the signal does not correlate with other current sensors or expected values.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
