What P0EDA means
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.
P0EDA at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0EDA
- Hybrid warning, often with further phase or sum codes
- Reduced charging and generator assist
Common causes of P0EDA
- Most likelyPhase Z current sensor offset or failure
- PossibleInverter fault on the phase Z bridge
- Less likelyPoor contact at the phase Z high-voltage terminal
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0EDA means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| DA | The exact fault in that area. |
What to do next
- Note P0EDA and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0EDA
What does P0EDA mean?
P0EDA means "Generator Phase Z Current". 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). It is a generic code, so it means the same on every make.
Is it safe to drive with P0EDA?
Drive gently and only to a workshop. With P0EDA the car can go into limp mode (reduced power) to protect itself.
Will P0EDA fail an emissions test?
Yes, it can. P0EDA is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0EDA to fix?
Difficulty: workshop only. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P0EDA clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
