P0E10Generator Inverter Power Supply A Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0E10 means supply A of the generator inverter is present but too low. Ford lists the code in the HEV OBD system summary for its power-split hybrids (OBDSM1901): in the paragraph on the gate signal lines of motor and generator, P0E10 appears with P0BCE and P0BCF among the generator-side open-circuit faults, while the motor side is covered by P0C0C. For Ford, P0E10 is therefore tied to the gate drive path of the generator inverter rather than to a separate supply part, and no voltage limit is published. CARB requires circuit monitoring for such hybrid components. A weak gate drive supply can leave the power switches only partly turned on so they overheat, which is why the inverter limits or stops the generator. Siblings: P0E0F and P0E11.
- What you may notice
- Hybrid system warning light and MIL on
- Generator limited or switched off, reduced hybrid performance
- Likely causes
- LikelyGate drive supply or gate signal path in the inverter faulty (Ford)
- PossibleLow 12 V supply to the inverter, e.g. weak battery or poor ground
- RareCorroded or loose inverter connector
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
