DTC codes / P0Cxx · Hybrid propulsion / P0CB1
P0CB1 indicates that the hybrid or electric vehicle battery temperature sensor N circuit is sending an intermittent or erratic signal to the battery energy control module. The computer has detected that the sensor's voltage or resistance readings are jumping around or dropping out unpredictably, rather than staying within a stable range.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
