What does code P0D6A mean?

Q: What does code P0D6A mean?

A/C Compressor Motor Voltage Sensor A Circuit High. P0D6A indicates that the powertrain control module (PCM) has detected an abnormally high voltage on the circuit that monitors the A/C compressor motor voltage sensor, specifically the 'A' sensor. This sensor is part of the air conditioning compressor's internal electronics and reports the motor's operating voltage back to the PCM, which uses it to regulate compressor operation and protect the system from overvoltage or undervoltage conditions.
