P0EDAGenerator Phase Z Current
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0EDA is the general current fault of phase Z, the last of the three X-Y-Z generator phases, without the detail of P0EDB (low) or P0EDC (high). No manufacturer documents P0EDA publicly. In a three-phase set the currents add up to almost zero at every instant, so a controller can calculate one phase from the other two or use the sum as a cross-check; Mitsubishi's Outlander PHEV, for instance, fails its generator sum check P0DFA when, with the switches off, the sum stays at 140 A or above for 0.35 s. A faulty Z current therefore often shows up together with sum or correlation faults. Under CARB these drive components must be supervised as well. Expect a hybrid system warning and limited generator operation. Phases X and Y: P0ED4, P0ED7.
- What you may notice
- Hybrid warning, often with further phase or sum codes
- Reduced charging and generator assist
- Likely causes
- LikelyPhase Z current sensor offset or failure
- PossibleInverter fault on the phase Z bridge
- RarePoor contact at the phase Z high-voltage terminal
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
