Q: What does code P2EA9 mean?

DC/AC Converter A Over Temperature. P2EA9 indicates that the vehicle's control module has detected an over-temperature condition in a DC-to-AC converter, which is the electronic assembly that turns high-voltage direct current into alternating current for an electric drive motor or accessory. The computer sets this code when the converter's internal temperature sensor reports a value above the calibrated safe limit, typically to protect the power electronics from heat damage.
