P0EDBGenerator Phase Z Current Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P0EDB means phase Z of the hybrid generator shows less current than the commanded operating point calls for. No manufacturer documents P0EDB publicly. Besides an absolute floor, published checks also look at the gap between actual and target current: Mitsubishi's Outlander PHEV fails a U-V-W phase not only when it hovers near zero under demand but also when it misses its target current. If phase Z falls short, the machine runs unbalanced, which causes torque ripple, humming and extra heat in the remaining phases, so the inverter lowers generator power. Likely causes are a loose or corroded high-voltage terminal, a broken lead in the winding, a power switch that no longer conducts or a sensor offset. High counterpart: P0EDC; general code: P0EDA.

- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
