Q: What does code P0E0C mean?

Generator Phase U-V-W Circuit/Open. P0E0C indicates that the generator control module has detected an open circuit in the phase U, V, or W winding circuit of the generator, which is the high-voltage motor-generator unit on hybrid and electric vehicles. The computer monitors the three-phase AC output for continuity and current flow, and this code sets when the expected electrical path is broken, preventing the generator from producing or receiving power correctly.
