DTC codes / P0Cxx · Hybrid propulsion / P0C87
P0C87 indicates that the hybrid or electric vehicle battery pack's temperature sensors G and H are reporting values that do not correlate with each other, meaning the battery energy control module sees a disagreement between two sensors that should track closely. The computer compares their readings under similar conditions and flags the code when the expected relationship falls outside a calibrated tolerance.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
