What does code P0CF6 mean?

Q: What does code P0CF6 mean?

Control Pilot Circuit High. P0CF6 indicates that the powertrain control module has detected an abnormally high voltage on the control pilot circuit, which is the communication line used to negotiate charging between an electric vehicle and its charging station. The circuit is expected to operate within a specific voltage range, and a high reading tells the module that the signal is out of bounds, often due to a wiring fault or a failure in the pilot signal generator.
