P0A67 Generator Inverter Sensor Circuit

P0A67 indicates a generator inverter sensor circuit problem. The controller cannot trust one of the sensor inputs used to monitor generator inverter operation.

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
Scope: iso-sae-controlled-p0
Standard: SAE J2012 / ISO 15031-6

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 open or disconnect generator inverter high-voltage circuits without proper disable and voltage verification steps.

Useful checks before replacing parts

Review generator inverter sensor data, phase current, voltage feedback, temperature feedback, generator command, freeze-frame data, and related sensor codes.
Inspect inverter sensor wiring, connector sealing, low-voltage grounds, reference supplies, water intrusion, shielded cable condition, and module terminals.
Compare sensor readings at key-on and under command to determine whether the fault is sensor, harness, inverter, or controller related.
