Q: What does code P0C87 mean?

Hybrid/EV Battery Temperature Sensor G/H Correlation. 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.
