Q: What does code P2E90 mean?

Battery Charger A Internal Power Supply Performance. P2E90 indicates that the battery charger module (often an auxiliary or onboard charger) has detected an internal fault in its own power supply circuitry, meaning the charger cannot reliably convert or regulate voltage for the high-voltage battery. The computer sets this code when the charger's internal self-test reports that its power supply performance is out of specification, typically due to a failed internal component or a supply voltage that falls outside the expected range.
