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.

Likely causes

Phase Z current sensor offset or failure

Inverter fault on the phase Z bridge

Poor contact at the phase Z high-voltage terminal

Symptoms

Hybrid warning, often with further phase or sum codes
Reduced charging and generator assist
