What does code P2EA8 mean?

Q: What does code P2EA8 mean?

DC/AC Converter A Input Voltage Too High. P2EA8 indicates that the powertrain control module has detected an abnormally high voltage at the input of DC/AC converter A, which is part of the high-voltage power system on hybrid and electric vehicles. The converter is responsible for transforming direct current from the battery into alternating current for the traction motor or other AC components, and the module sets this code when the input voltage exceeds the expected threshold.
