P0E04Generator Phase V 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
- P0E04 is the general circuit code for the generator inverter's V-phase current sensor, meant for an electrical fault that is not narrowed down to offset, low or high. No manufacturer documents P0E04 publicly. Phase V is a special case: the 2018 Outlander PHEV measures generator current with only two sensors, on phases U and W (P0E01 to P0E03, P0E09 to P0E0B), since the third current follows arithmetically from the other two. Only the 2023 model adds its own V-phase sensor, and there its faults are reported solely through P0E05 to P0E07. CARB requires electrical monitoring of hybrid components that affect emissions. If the code does appear, check the inverter connectors and look for further phase sensor codes. Matching codes for phases U and W: P0E00 and P0E08.
- What you may notice
- Hybrid or engine warning light on
- Reduced generator output
- Likely causes
- PossibleElectrical fault in the V-phase sensor circuit inside the inverter
- PossiblePoor contact at the inverter or generator control unit connector
- RareGenerator control unit faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
