P0E00Generator Phase U Current Sensor Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0E00 is the general circuit code for the current sensor in phase U of the generator. Each phase sensor, usually a Hall-type device inside the inverter, outputs a voltage around a mid-point when no current flows. No manufacturer documents P0E00 publicly. Mitsubishi's Outlander PHEV shows how its generator unit judges the U-phase sensor: at standstill below 20 rpm with the IGBTs off the signal must stay between 2.3 and 2.7 V (P0E01-00 after 0.32 s), and readings of 0.5 V and lower, or 4.5 V and higher, held for 0.2 s set P0E02-00 or P0E03-00. P0E00 is meant for circuit faults outside these categories. Without the signal the inverter cannot regulate generator torque properly. Phases V and W are P0E04 and P0E08.
- What you may notice
- Hybrid system warning and engine warning light
- Generator switched off, reduced performance
- Vehicle may not reach ready mode
- Likely causes
- PossibleSupply or reference fault of the current sensor
- PossibleDefective phase U current sensor inside the inverter
- RareFaulty internal connection between sensor and control board
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
