P0A0E DC/DC Converter Status Circuit High Input

P0A0E indicates a high input on the DC/DC converter status circuit. The converter feedback signal is above the voltage or logic state expected by the controller.

Code status

Needs verification

Not yet verified against SAE J2012_202509 / J2012DA. Treat unverified rows as a lookup aid, not repair authority.

System: Hybrid / EV

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not assume the converter is charging correctly from status feedback alone; verify actual 12-volt system voltage.

Useful checks before replacing parts

Check converter status voltage, converter enable command, 12-volt charging voltage, high-voltage readiness, freeze-frame data, and related high-input codes.
Inspect for short-to-voltage faults, open grounds, backfeed from low-voltage circuits, connector corrosion, water intrusion, and damaged status wiring.
Confirm whether the DC/DC converter output is normal while the status feedback remains high or stuck.
